Zimmer Instrument Care, Cleaning, Maintenance and Sterilization Instructions
1. PURPOSE
These instructions are recommended for the care,
cleaning, maintenance and sterilization of reusable
Zimmer orthopaedic manual surgical instruments. This
document is intended to assist health care personnel
in safe handling practices, effective reprocessing and
maintenance of Zimmer reusable devices. It provides
information complementary to the instructions for use
in fulfillment of ISO 17664, ANSI/AAMI ST81, and the
European Council Directive 93/42/EEC, Annex 1, section
13.6 (h).
The instructions are intended to assist the hospital and
central supply management in developing procedures
for safe and effective reprocessing of Zimmer instrument
sets.
Hospital personnel, including those in receiving and
central sterile supply departments (CSSD), as well as
in the operating room (OR), may be directly involved
in handling instruments purchased from Zimmer or
on a loan basis as consignment instruments. Hospital
directors and other management in each of these
departments should be informed of these instructions
and recommendations to ensure safe and effective
reprocessing and to prevent damage or misuse of
reusable devices.
2. SCOPE
This instruction manual provides information on
the care, cleaning, disinfection, maintenance
and sterilization of manual surgical instruments
and is applicable to all reusable medical devices
manufactured and/or distributed by Zimmer, Inc.
This information is also applicable to single-use
medical devices manufactured by Zimmer that are
supplied non-sterile but are intended to be used in
a sterile state and single-use devices packaged and
sold sterile but removed from packaging and placed
in kits (e.g. screws, plates, etc.). These devices are
single-use but can be reprocessed if not used.
Note: not used refers to those single-use
components that have not been in contact with
blood, bone, tissue, or other body fluids. Any
unused, single-use device that has been exposed
to blood, bone, tissue, or body fluids must not be
reprocessed and must be discarded.
Always consult the device labeling and instructions
for use for specific recommendations or restrictions
on processing within a health care setting.
Devices that cannot be reused may be labeled with
the following symbol:
ISO 15223-1 5.4.2
Do not reuse
This information is not applicable to singleuse devices that are sold sterile and cannot be
resterilized (e.g. osteotome blades).
Devices that cannot be resterilized may be labeled
with the following symbol:
ISO 15223-1 5.2.6
Do not resterilize
This instruction manual is not applicable to air
driven or electrically powered equipment. However,
it is applicable to functional attachments (e.g.
reamers and drill bits) that are connected to
powered equipment for use.
Powered devices included in a manual device
case must be cleaned per specific manufacturer’s
instructions (e.g. Brasseler powered hand pieces).

ISO 15223-1 5.2.6
Do not resterilize
Sterile: free from all viable microorganisms.
Sterilization: a validated process used to render a device free
from all forms of viable microorganisms.
Note: In a sterilization process, the nature of microbiological
death is described by an exponential function. Therefore, the
presence of microorganisms on any individual item may be
expressed in terms of probability. While this probability may be
reduced to a very low number, it can never be reduced to zero.
This probability can only be assured for validated processes.

6. CONSIDERATIONS
This instruction manual pertains to all hip, knee, trauma,
and extremity reusable medical devices manufactured
and/or distributed by Zimmer, Inc. This manual also
pertains to all hip, knee, trauma, and extremity single-use
medical devices manufactured by Zimmer that are supplied
nonsterile but are intended to be used in a sterile state.
This manual does not pertain to Zimmer spine or dental
devices. This information should be studied carefully.
This manual supercedes Zimmer, Centerpulse, and Implex
manual orthopaedic instrument reprocessing instructions
and instrument manuals published prior to Revision Date
2015.
The user/processor should comply with local laws and
ordinances in countries where reprocessing requirements
are more stringent than those detailed in this manual.
New and used instruments must be thoroughly processed
according to these instructions prior to use. It is also
Zimmer’s recommendation to thoroughly process nonsterile implants (e.g. plates, screws, etc.) prior to use.
Single-use devices must be removed from the tray or caddy
for the initial cleaning process and returned to the tray or
caddy for sterilization. Upon subsequent reprocessing,
however, unused single-use devices may be left in the tray
or caddy.
Note: Any unused, single-use device that has been
exposed to blood, bone, tissue or body fluids must not be
reprocessed and must be discarded.
During musculoskeletal surgery, instruments become
contaminated from blood, tissue, bone fragments and
marrow. The instruments may also become contaminated
with body fluids containing hepatitis virus, HIV or other
etiological agents and pathogens. All health care workers
should become familiar with the necessary Universal
Precautions of preventing injuries caused by sharp
instruments when handling these devices during and after
surgical procedures and during reprocessing.
It should be noted that saline and other irrigation fluids
such as Ringers Solution are often used in copious amounts
during surgical procedures and may cause corrosion of the
instruments.
Orthopaedic surgery requires instruments which are heavy
and have multiple components, articulating or rotating
parts, removable handles, plastic replacement parts, and
series of gauges or other measuring devices in graduated
sizes. Devices are usually supplied in sets and subdivided
into trays and cases in which the devices may be arranged
by size or in the order needed for a specific surgical
procedure.
Hospitals must assume responsibility for cleaning,
disinfection, packaging and sterilization of all loaner
instrument sets before returning them to Zimmer. However,
the next user must also inspect the set upon receipt to
verify that instruments have, in fact, been adequately
cleaned and decontaminated before repeating reprocessing
procedures to prepare the loaner set for subsequent reuse.
Zimmer cannot guarantee that sterility was attained by
the previous user and has been maintained during transit.
Zimmer representatives often open and inspect instrument
sets between users, which will, of course, compromise
cleanliness and sterility and require complete reprocessing
prior to subsequent use. Zimmer requires certification of
cleaning and disinfection prior to return of loaner sets to
Zimmer.
This reprocessing manual includes instructions for Zimmer
reusable devices marked with reprocessing category codes
[a, a+, b, b+, c]. See Section 7 of this manual for further
explanation of reprocessing codes. All Zimmer devices
may be safely and efficiently reprocessed using either
the rigorous manual or combination method cleaning
instructions outlined in this reprocessing manual. The
combination method which includes an automated process
is preferable.
Core orthopaedic instrument sets must be complete and in
good condition to be used correctly. Optional devices may
be available on request from your Zimmer representative.

7. PROCESSING CATEGORY CODES
Zimmer recommends that all reusable devices (regardless of etching) be processed in accordance with the rigorous
manual or combination cleaning instructions contained in this reprocessingmanual. The following codes are etched on
some devices and case components and may provide useful information in the selection of cleaning agents as well as
indications for disassembly.
Note: Codes on trays and cases apply only to those components noted and do not apply to the contents of the tray or case.
a
Metal devices (excluding aluminum and titanium) and case components without features posing
a cleaning challenge or non-metal/polymer handles, or other components (e.g. retractors,
drills, testing trays, rasps, scissors, clamps, exploring hooks, compression forceps, skin bridge
elevators, guide wires, etc.). These devices are tolerant of alkaline cleaning agents when followed
by neutralization and thorough rinsing. These devices can be treated with rust-removal agents
approved for surgical instruments if needed.
a+
Metal devices (excluding aluminum and titanium) and case components with features posing a
cleaning challenge but without non-metal/polymer handles or other components (e.g. drills with
elongated holes, belt tensioning pulleys, bone joint reamers, extractor cases). These devices are
tolerant of alkaline cleaning agents when followed by neutralization and thorough rinsing. These
devices can be treated with rust-removal agents approved for surgical instruments if needed.
b
b+
c
Devices and case components without features posing a cleaning challenge made of polymers or
metal instruments paired with polymer components (e.g. testing trays for flat profiles, chisels with
non-metal handles, awls, dissectors, femur dilatators, pyramidal chisels/rasps). These devices
are tolerant of alkaline cleaning agents when followed by neutralization and thorough rinsing.
Devices and case components with features posing a cleaning challenge, made of polymers
or metal instruments paired with polymer components (e.g. tibial mallets, flex screwdrivers,
tibial dilatators, etc.). These devices are tolerant of alkaline cleaning agents when followed by
neutralization and thorough rinsing.
Devices and case components made of titanium or aluminum alloys and/or having assembly/
disassembly or other reprocessing aids (e.g. torque spanners, tibial aiming devices, pad cutters,
instrument cases, trays and sterilization containers). The use of alkaline cleaning agents might be
corrosive to the surface of these devices.
Note: Features posing a cleaning challenge include: lumens/cannulated bores, tightly mated surfaces, rough surfaces,
ball detents, springs, and multiple component designs.

8. PROCESSING INSTRUCTIONS
These processing instructions are intended to assist the
hospital and central supply management in developing
procedures to attain safe and effective devices, both
for hospital-owned and for loaned instrument sets. This
information is based on Zimmer testing, experience
and material science, as well as widely accepted
recommendations of the following organizations:
•
American National Standards Institute (ANSI)
•
American Society for Testing and Materials (ASTM)
•
Association for the Advancement of Medical
Instrumentation (AAMI)
•
Association for Applied Hygiene (VAH)
•
Association of Operating Room Nurses (AORN)
•
Canadian Standards Association (CSA)
•
Centers for Disease Control (CDC)
•
Federal Institute for Drugs and Medical Devices
(BfArM, Bundesinstitut für Arzneimittel und
Medizinprodukte)
•
German Instrument Working Group (AKI)
Arbeitskreis Instrumenten-Aufbereitung
•
International Standards Organization (ISO)
•
International Association of Healthcare Central
Service Material Management (IAHCSMM)
•
National Health Service (NHS)
•
Robert Koch Institute (RKI)
•
Swissmedic
•
World Health Organization (WHO)
Note: These instructions describe the necessary
processing steps that new and used instruments must
undergo to attain sterility.
•
Metal brushes or scouring pads must not be used
during manual cleaning procedures. These materials
will damage the surface and finish of instruments. Softbristled, nylon brushes and pipe cleaners should be
used.
•
Cleaning agents with low foaming surfactants should
be used during manual cleaning procedures to ensure
that instruments are visible in the cleaning solution.
Manual scrubbing with brushes should always be
performed with the instrument below the surface of the
cleaning solution to prevent generation of aerosols and
splashing which may spread contaminants. Cleaning
agents must be completely rinsed from device surfaces
to prevent accumulation of detergent residue.
•
Do not stack instruments or place heavy instruments on
top of delicate devices.
•
Dry, soiled surgical instruments are more difficult to
clean. Do not allow contaminated devices to dry prior to
reprocessing. All subsequent cleaning and sterilization
steps are facilitated by not allowing blood, body fluids,
bone and tissue debris, saline, or disinfectants to dry
on used instruments.
•
Saline and cleaning/disinfection agents containing
aldehyde, mercury, active chlorine, chloride, bromine,
bromide, iodine or iodide are corrosive and should not
be used. Instruments must not be placed or soaked in
Ringers Solution.
•
Lubricants not specifically designed for compatibility
with steam sterilization should not be used because
they may: 1) coat microorganisms; 2) prevent direct
contact of the surface with steam; and 3) are difficult to
remove.
•
Only devices manufactured and/or distributed by
Zimmer should be included in Zimmer instrument trays
and cases. These validated reprocessing instructions
are not applicable to Zimmer trays and cases that
include devices that are not manufactured and/or
distributed by Zimmer.
•
Descaling agents that include morpholine should not be
used in steam sterilizers. These agents leave residue
which can damage polymer instruments over time.
Steam Sterilizers should be descaled in accordance
with the manufacturer’s instructions.
A. Warnings and Precautions
•
•
Universal Precautions should be observed by all
hospital personnel that work with contaminated or
potentially contaminated medical devices. Caution
should be exercised when handling devices with
sharp points or cutting edges.
Personal Protective Equipment (PPE) should be
worn when handling or working with contaminated
or potentially contaminated materials, devices and
equipment. PPE includes gown, mask, goggles or
face shield, gloves and shoe covers.

Zimmer Instrument Care, Cleaning, Maintenance and Sterilization Instructions
B. Receiving Inspection – Instrument set
content and functionality verification.
•
•
•
Upon receipt in the hospital, instrument sets should
be inspected for completeness. Inspect for thumb,
wing, set, or other types of screws; screw-in or other
detachable handles; and auxiliary exchangeable
parts such as blades, right/left attachments or
heads. Many organizing cases have shadow graphs,
outlines, catalog numbers, and instrument names or
sizes silk-screened or otherwise marked on the case
or tray.
Orthopaedic surgical procedures follow a precise
order in which the instruments are used. Also,
many instruments have dimensional features which
govern bone resections, determine implant sizes,
and measure intramedullary canal sizes, depth of
drill holes, angles of tube/plate, acetabular cup
placements, etc. Therefore, it is very important that
all requested sizes of a specific instrument series
are available (specific instruments are routinely
omitted from instrument sets due to infrequent use
unless requested by the user). Contact your Zimmer
representative if requested instruments have been
omitted but are required for surgery.
Markings on instruments used for measuring
anatomical dimensions must be legible. These
may include gauge markings, angles, inner or outer
diameters, length or depth calibrations, and right/
left indications. Notify your Zimmer representative if
scales and other markings are not legible.
Note: It is important to select enzymatic solutions intended
for breakdown of blood, body fluids and tissues. Some
enzymatic solutions are specifically for breakdown of fecal
matter or other organic contaminants and may not be
suitable for use with orthopaedic instruments.
•
Repeated processing, according to the instructions in
this manual has minimal effect on Zimmer reusable
manual instruments unless otherwise noted. End of life
for stainless steel or other metal surgical instruments
is normally determined by wear and damage due to the
intended surgical use and not to reprocessing.
•
Automated cleaning using a washer/disinfector
alone may not be effective for complex orthopaedic
instruments with lumens, cannulations, blind holes,
mated surfaces and other features. Either the
rigorous manual or combination cleaning process is
recommended with the combination process being
preferable.
•
Where applicable, multi-component instruments should
be disassembled for cleaning. Disassembly, where
necessary, is generally self evident. More specific
instructions can be found in the instructions for use
and at www.zimmer.com. Care must be taken to avoid
losing small parts. If a part is lost, notify your Zimmer
representative when the instrument set is returned.
•
At point of use, soiled instruments must be removed
from metal or polymer trays and moistened to
prevent debris from drying before transportation to
the reprocessing area for manual and/or automated
cleaning procedures. Do not clean soiled instruments
while in polymer or metal trays. Single-use devices
must be cleaned separately from soiled instruments.
C. Limitations and Restrictions
•
Neutral pH, enzymatic, and alkaline (pH ≤12)
cleaning agents are recommended and preferred for
cleaning Zimmer reusable devices. Alkaline agents
with pH ≤ 12 may be used to clean stainless steel
and polymer instruments in countries where required
by law or local ordinance; or where prion diseases
such as Transmissible Spongiform Encephalopathy
(TSE) and Creutzfeldt-Jakob Disease (CJD) are a
concern. It is critical that alkaline cleaning agents
are thoroughly neutralized and completely rinsed
from devices.
Note: Drill bits, reamers, rasps and other cutting devices
should be carefully inspected after processing with alkaline
detergents to ensure that cutting edges are fit for use.
Note: Any unused, single-use device that has been
exposed to blood, bone, tissue, or body fluids must not be
reprocessed and must be discarded.
•
Polymers used in Zimmer instrument sets can be
sterilized using steam/moist heat. Polymer materials
have a limited useful life. If polymer surfaces turn
“chalky,” show excessive surface damage (e.g. crazing
or delamination), or if polymer devices show excessive
distortion or are visibly warped, they should be
replaced. Notify your Zimmer representative if polymer
devices need to be replaced.

Zimmer Instrument Care, Cleaning, Maintenance and Sterilization Instructions
•
•
•
Most currently available polymers will not withstand
conditions in washers/sterilizers that operate at
temperatures equal to or greater than 141°C / 285°F,
and use live-steam jets as cleaning features. Severe
surface damage to polymer devices may occur under
these conditions.
Soaking in disinfectants may be a necessary step
to control certain viruses. However, these agents
may discolor or corrode instruments (household
bleach contains or forms chlorine and chloride
in solution and has a corrosive effect similar to
saline). Disinfectants containing glutaraldehyde,
or other aldehydes may denature protein based
contaminants, causing them to harden and making
them difficult to remove. Where possible, soaking in
disinfectants should be avoided.
Steam/moist heat is the recommended sterilization
method for Zimmer devices.
•
Ethylene Oxide (EO), Gas Plasma Sterilization and dry
heat sterilization methods are not recommended for
sterilization of Zimmer devices.
•
Instruments with removable polymer sleeves must be
disassembled for sterilization (e.g. acetabular reamer
shaft with sleeve, side cutters, etc.)
•
During initial steam sterilization runs some
formaldehyde from polyformaldehyde surfaces may
vaporize and become noticeable. This should not
cause concern. After a few sterilization cycles, the
odor should be no longer evident.
•
•
While ethylene oxide sterilization may prolong the
service life of certain polymers (e.g. polysulfone),
this method of sterilization is not recommended
for Zimmer devices. Large polyformaldehyde items
(Delrin®, Celcon®) have been found to require
excessive outgassing times (a minimum of five days
at elevated temperatures in a mechanical aerator);
therefore, gas sterilization for polyformaldehyde
products is contraindicated.
Titanium and titanium alloy devices are especially
susceptible to discoloration from steam impurities
and detergent residues which form multi-colored
surface layers of oxide deposits. Upon repeated
sterilization these oxide layers, while not harmful
to the patient, may become dark and obscure
graduation marks, item and lot numbers, and
other stamped or etched information. Acidic,
anti-corrosion agents may be used to remove this
discoloration as needed.
•
Stainless steel instruments may be treated with rustremoval agents approved for surgical instruments if
needed.
•
Use of hard water should be avoided. Softened tap
water may be used for initial rinsing. Purified water
should be used for final rinsing to eliminate mineral
deposits on instruments (e.g. ultra-filter (UF), reverseosmosis (RO), deionized (DI), or equivalent).
D. Point-of-Use Preparation for Reprocessing
•
Remove excess body fluids and tissue from instruments
with a disposable, non-shedding wipe. Place
instruments in a basin of distilled water or in a tray
covered with damp towels. Do not allow saline, blood,
body fluids, tissue, bone fragments or other organic
debris to dry on instruments prior to cleaning.
Note: Soaking in proteolytic enzyme solutions or other
precleaning solutions facilitates cleaning, especially in
instruments with complex features and hard-to-reach
areas (e.g. cannulated and tubular designs, etc.). These
enzymatic solutions as well as enzymatic foam sprays
break down protein matter and prevent blood and
protein based materials from drying on instruments.
Manufacturer’s instructions for preparation and use of
these solutions should be explicitly followed.
•
For optimal results, instruments should be cleaned
within 30 minutes of use or after removal from solution
to minimize the potential for drying prior to cleaning.
•
Used instruments must be transported to the central
supply in closed or covered containers to prevent
unnecessary contamination risk.
E. Preparation Before Cleaning
•
Symbols or specific instructions etched on instruments
or instrument trays and cases should be strictly
followed.
•
Where applicable multi-component instruments
should be disassembled for appropriate cleaning.
Care should be exercised to avoid losing small screws
and components. If a part is lost, notify your Zimmer
representative when the instrument set is returned.
•
Instructions for instrument assembly/disassembly
and device specific cleaning aids can be found at www.
zimmer.com.
Page 11
Zimmer Instrument Care, Cleaning, Maintenance and Sterilization Instructions
F. Preparation of Cleaning Agents
• Neutral pH, enzymatic, and alkaline cleaning agents
with low foaming surfactants are recommended by
Zimmer.
• Alkaline agents with pH ≤ 12 may be used in countries
where required by law or local ordinance. Alkaline
agents should be followed with a neutralizer and/or
thorough rinsing.
• Only agents with proven efficacy (FDA approved, VAH
listed, or CE mark) should be used. As a large variety
of cleaning agents and disinfectants exists around the
globe, Zimmer does not recommend any specific brand.
• Agents used during the validation of these processing
instructions are: Steris®, Prolystica™ 2X Enzymatic
Pre Soak and Cleaner, Prolystica™ Ultra Concentrate
Neutral Detergent, neodisher® FA Alkaline Detergent,
neodisher® Z Acid Neutralizer.
• All cleaning agents should be prepared at the usedilution and temperature recommended by the
manufacturer. Softened tap water may be used
to prepare cleaning agents. Use of recommended
temperatures is important for optimal performance of
cleaning agents.
• Dry powdered cleaning agents should be completely
dissolved prior to use to avoid staining or corrosion of
instruments and to ensure correct concentration.
• Fresh cleaning solutions should be prepared when
existing solutions become grossly contaminated
(bloody and/or turbid).
Note: Manual cleaning may require onsite validation
by the healthcare facility and appropriate procedures/
documentation should be in place to avoid human factor
variability.
• The combination method is preferred and can be used
for all devices.
G. Rigorous Manual Cleaning/Disinfection
Instructions
1. Completely submerge instruments in an enzyme
or alkaline (pH ≤12) solution and allow to soak for
20 minutes. Use a soft-bristled, nylon brush to
gently scrub the device until all visible soil has been
removed. Particular attention must be given to
crevices, lumens, mated surfaces, connectors and
other hard-to-clean areas. Lumens should be cleaned
with a long, narrow, soft-bristled brush (i.e. pipe
cleaner brush).
2. Remove the instruments from the enzyme solution
and rinse in tap water for a minimum of 3 minutes.
Thoroughly and aggressively flush lumens, holes and
other difficult-to-reach areas.
3. Place prepared cleaning agents in a sonication unit.
Completely submerge device in cleaning solution and
sonicate for 10 minutes at 45-50 kHz.
4. Rinse instrument in purified water for at least 3
minutes or until there is no sign of blood or soil on
the device or in the rinse stream. Thoroughly and
aggressively flush lumens, holes and other difficultto-reach areas.
5. Repeat the sonication and rinse steps above.

should be strictly adhered to. Use only cleaning agents
recommended for the specific type of automated washer/
disinfector. A washer/disinfector with approved efficacy
(e.g. CE mark, FDA approval, and validation according to
ISO 15883) should be used.
4. Proceed to Section 8J, Inspection, Maintenance,
Testing, and Lubrication.
I. Automated Only Cleaning/Disinfection
Instructions
1. Automated washer/disinfector systems are not
recommended as the sole cleaning method for
surgical instruments that are not of simple design.
Orthopaedic instruments with any features such as
multiple components, lumens/cannulations, blind
holes, mated surfaces, connectors and internal
mechanisms should be cleaned following the
rigorous manual or combination cleaning procedure
outlined in this reprocessing manual except where
specifically indicated.
2. Simple instruments without any features such as
multiple components, lumens/cannulations, blind
holes, mated surfaces, connectors and internal
mechanisms may be successfully cleaned and
disinfected using a typical washer/disinfector cycle
for surgical instruments as outlined in Table 2 or
Table 3 of this reprocessing manual. Devices should
be thoroughly inspected prior to sterilization to
ensure effective cleaning.
J. Inspection, Maintenance, Testing and
Lubrication
1. Carefully inspect each device to ensure that all visible
contamination has been removed. If contamination
is noted repeat the cleaning/disinfection process.
Page 13
Zimmer Instrument Care, Cleaning, Maintenance and Sterilization Instructions
2. Visually inspect for completeness, damage and/or
excessive wear.
Note: If damage or wear is noted that may compromise
the function of the instrument, contact your Zimmer
Representative for a replacement.
3. Check the action of moving parts (e.g. hinges, boxlocks, connectors, sliding parts, etc.) to ensure
smooth operation throughout the intended range of
motion.
4. If necessary, hinged, rotating, or articulating
instruments can be lubricated with an instrument
product (e.g. Instrument Milk or equivalent lubricant)
specifically designed for compatibility with steam
sterilization.
Note: These lubrication instructions are not applicable
to air-powered or electrical instruments. These devices
have different requirements and should be lubricated
according to the manufacturer’s instructions.
5. Check instruments with long slender features
(particularly rotating instruments) for distortion.
6. Where instruments form part of a larger assembly,
check that the devices assemble readily with mating
components.
K. Sterile Packaging
Packaging instrument sets in rigid trays and cases with
lids
Safety Precaution: The total weight of a wrapped
instrument tray or case should not exceed 11.4kg/25lbs.
Instrument cases may be placed in an approved
sterilization container with gasketed lids at the
user’s discretion. Consult the Zimmer website
www.zimmer.com or your Zimmer representative for the
full list of approved sterilization containers. The total
weight of the instrument set, case, and sterilization
container, must not exceed 11.4kg/25lbs (other local
limits below 25 lbs may apply).
•
Trays and cases with lids may be wrapped in
standard medical grade, steam sterilization wrap
using the AAMI double wrap method or equivalent.
•
Trays and cases with lids may also be placed in an
approved sterilization container with gasketed lid for
sterilization.
•
Follow the sterilization container manufacturer’s
instructions for inserting and replacing sterilization
filters in sterilization containers.
Instrument trays and cases with defined, preconfigured
layouts
•
Areas designated for specific devices shall contain
only devices specifically intended for these areas.
•
Optional Zimmer instruments should not be added
to a preconfigured instrument tray or case unless a
dedicated universal space or compartment has been
included in the design and the guidelines described
below for trays and cases without defined layouts or
universal spaces can be applied.
•
Only devices manufactured and/or distributed by
Zimmer should be included in Zimmer instrument
trays. These validated reprocessing instructions are
not applicable to Zimmer trays that include devices
that are not manufactured and/or distributed by
Zimmer.
Packaging individual instruments
•
•
Single devices should be packaged in a medical
grade sterilization pouch or wrap which conforms
to the recommended specifications for steam
sterilization provided in the table below. Ensure
that the pouch or wrap is large enough to contain
the device without stressing the seals or tearing the
pouch or wrap.
Standard medical grade, steam sterilization wrap
may be used to package individual instruments. The
package should be prepared using the AAMI double
wrap or equivalent method.
Note: If sterilization wraps are used they must be
free of detergent residues. Reusable wraps are not

keep devices in place.
•
Only devices manufactured and/or distributed by
Zimmer should be included in Zimmer instrument
trays. Zimmer validated reprocessing instructions
are not applicable to Zimmer trays that include
devices that are not manufactured and/or distributed
by Zimmer.
•
Brackets designed to force disassembly of a complex
device must not be altered to allow the assembled
device to be inserted into the tray or case.
•
To ensure devices are fully seated in their
corresponding brackets and to prevent damage to
tray contents, individual brackets should not overlap
one another when inserted into the tray floor.
Note: Some individual brackets may be designated for
assembly onto other “host” brackets. In these instances,
the mating relationship between the brackets will be
graphically depicted on the face of the “host” bracket.
•
Bracket fasteners should be fully engaged with the
tray floor to prevent unintended migration, damage
and/or loss of tray contents.
•
Wave springs positioned over the shaft of the
bracket fasteners are intended to stabilize brackets
by minimizing free-play between them and the tray
floor. To ensure intended function, periodically
inspect brackets for damaged and/or missing springs
which can be replaced by contacting your Zimmer
representative.
L. Sterilization Instructions
•
See Table 4 for recommended minimum sterilization
parameters that have been validated by Zimmer to
provide a 10-6 sterility assurance level (SAL).
•
The hospital is responsible for in-house procedures
for the reassembly, inspection, and packaging of the
instruments after they are thoroughly cleaned in a
manner that will ensure steam sterilant penetration
and adequate drying. Provisions for protection of
any sharp or potentially dangerous areas of the
instruments should also be recommended by the
hospital.
•
Moist heat/steam sterilization is the preferred and
recommended method for Zimmer reusable devices.
Sterilizer manufacturer recommendations should
always be followed. When sterilizing multiple
instrument sets in one sterilization cycle, ensure that
the manufacturer’s maximum load is not exceeded.
Instrument sets should be properly prepared and
packaged in trays and/or cases that will allow
steam to penetrate and make direct contract with all
surfaces.
•
Identification tags and associated labels on trays
should correspond to tray contents to ensure correct
trays are available for use in surgery.
•
•
Any manual tools provided by Zimmer to aid in the
removal of individual brackets must not remain in
the instrument trays during reprocessing and are not
intended for use in surgery.
•
Universal instrument trays and cases without defined,
preconfigured layouts or containing undefined universal
spaces or compartments should only be used under the
following conditions:
•
Ethylene oxide or gas plasma sterilization methods
should not be used unless package inserts for the
applicable product specifically provide instructions
for sterilization using these methods.

on a sterilization container have been opened or
compromised, the sterile filters must be replaced and
the instrument set resterilized.
9. HOSPITAL RESPONSIBILITIES FOR ZIMMER
LOANER SETS
•
Orthopaedic surgical instruments generally have
a long service life; however, mishandling or
inadequate protection can quickly diminish their life
expectancy. Instruments which no longer perform
properly because of long use, mishandling, or
improper care should be returned to Zimmer to be
discarded. Notify your Zimmer representative of any
instrument problems.
•
Loaner sets should undergo all steps of
decontamination, cleaning, disinfection, inspection,
and terminal sterilization before being returned to
Zimmer. Documentation of decontamination should
be provided with instruments being returned to
Zimmer.
•
Missing or damaged instruments from loaner sets
should be brought to the attention of the operating
room supervisor, to the director of the central supply
department, and to your Zimmer representative to
ensure that the next hospital will receive a complete
set of instruments in good working condition.

Zimmer Instrument Care, Cleaning, Maintenance and Sterilization Instructions
Appendix 1- Cleaning/Disinfection/Sterilization Validation Process
Zimmer rigorous manual cleaning and disinfection methods are developed using spore logarithmic reduction and
visual inspection criteria to determine critical cleaning parameters. The reusable devices or device features are
exposed to blood soil containing approximately 106 spores per ml. The samples are allowed to dry for 30 minutes prior
to cleaning/disinfection. After cleaning, the test samples are visually inspected for any sign of remaining blood soil.
Bioburden extractions are performed to determine the number of spores remaining on the test samples. The data are
compared to positive controls to determine if the acceptance criteria are met.
Zimmer combination (with automated process) cleaning and disinfection methods are developed using total protein,
total organic carbon, and visual inspection criteria to determine critical cleaning parameters. The reusable devices or
device features are exposed to blood soil and allowed to dry for 24 hours prior to cleaning/disinfection. After cleaning,
test samples are inspected for any sign of visible soil and extracted to determine the quantitative amount of extractable
protein and organic soil. The data are compared to test protocol requirements to determine if the acceptance criteria
are met.
The cleaning/disinfection processes outlined in this manual have been validated per the following standards:
ISO 17664, Sterilization of medical devices – Information to be provided by the manufacturer for the processing of
resterilizable medical devices
Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling Guidance for Food and Drug
Administration Staff
All reusable devices are reviewed to ensure that the device features are not more challenging than those validated.
As new, more challenging features emerge, the features are validated or the device is modified to a less challenging
design.
Zimmer prevacuum (pressure pulse) and gravity moist heat sterilization cycles are developed using F0 data to establish
critical cycle parameters. Calibrated thermocouples are placed in the most challenging locations within the instrument
cases for heat penetration studies. Moist heat cycles are validated using microbial challenge half-cycle studies to prove
lethality via the “overkill” method to demonstrate a 10-6 or better sterility assurance level (SAL). This method utilizes
biological indicators (BI) inoculated with more than one million (106) resistant spores (Geobacillus stearothermophilus)
placed in the most challenging locations within the instrument set. Studies are conducted using disposable moist
heat sterilization wrap and/or approved rigid steam sterilization containers. Successful half-cycle microbial challenge
studies result in total kill of all BIs demonstrating a spore logarithm reduction of at least twelve (10-6 SAL or better)
for the most resistant microorganism at a population of greater than one million. Recommended dry time is validated
by demonstrating that pre-sterilization and post sterilization case weight is within ± 3 percent with no visible moisture
at the end of the full sterilization cycle. Durability studies are also performed using multiple cycles at 135°C for 18
minutes to ensure that the instrument case and contents can withstand repeated processing at maximum parameters.
The sterilization parameters outlined in this manual are validated per the following standards:
ANSI/AAMI ST79, Comprehensive guide to steam sterilization and sterility assurance in health care facilities
ANSI/AAMI/ISO 17665, Sterilization of health care products – Moist heat – Part 1: Requirements for the development,
validation, and routine control of a sterilization process for medical devices
