![• The total weight of a wrapped instrument tray or case should not exceed 11.4kg/25lbs. When placed in a sterilization container with gasketed lid the total sterilization package should not exceed 16kg/35lbs. • Any device capable of disassembly must be disassembled prior to placement in the case. • All devices must be arranged to ensure steam penetration to all instrument surfaces. Instruments should not be stacked or placed in close contact. • The user must ensure that the instrument case is not tipped or the contents shifted once the devices are arranged in the case. Silicon mats may be used to 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. Sterilization • Disinfection is only acceptable as a precursor to full sterilization for reusable surgical instruments. See Table 6 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 orthopaedic instrument sets. • 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. • 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. • Gravity displacement sterilization cycles are not recommended because cycle times are too long to be practical. Storage • Sterile, packaged instruments should be stored in a designated, limited access area that is well ventilated and provides protection from dust, moisture, insects, vermin, and temperature/ humidity extremes. Hospital Responsibilities for Zimmer Loaner Instruments • 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. Instrument Care, Cleaning and Sterilization Table 6.

Instrument trays, cases and lids must be cleaned separately. Non-sterile, single-use plate and screw implants are an exception to this rule. Plates and screws may remain in the tray or caddy for reprocessing.
• Repeated processing, according to the instructions in this manual has minimal affect 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. • 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. One or more of the following processes may be used to purify water: ultra-filter (UF), reverse-osmosis (RO), deionized (DI), or equivalent. • Ethylene oxide (EO), gas plasma and dry heat sterilization methods are not recommended for sterilization of Zimmer reusable instruments. Steam (moist heat) is the recommended sterilization method for Zimmer instruments.
Instructions Point of Use • Remove excess body fluids and tissue from instruments with a disposable, non-shedding wipe. Place devices in a tray of distilled water or cover with damp towels. • Instruments should be cleaned within 30 minutes of use 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.
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. Disassembly, where necessary is generally self-evident. Care should be exercised to avoid losing small screws and components.
Manual Cleaning/Disinfection Procedure
Inspection, Testing, Maintenance & Lubrication
Note: If stainless steel instruments are stained or corroded, an acidic, anti-corrosion agent in an ultrasonic cleaner may be sufficient to remove surface deposits. Care must be taken to thoroughly rinse acid from devices. Acidic, anti-corrosion agents should only be used on an as needed basis.
Step 1
Completely submerge instruments in enzyme solution and allow to soak for 20 minutes. Scrub using a soft-bristled, nylon brush until all visible soil has been removed.
Step 2
Remove the device from the enzyme solution and rinse in tap water for a minimum of 3 minutes. Throughly and aggressively flush lumens, holes and other difficult to reach areas.
• Carefully inspect each device to ensure that all visible contamination has been removed. If contamination is noted, repeat the cleaning/disinfection process. • Check the action of moving parts (e.g. hinges, box-locks, connectors, sliding parts, etc.) to ensure smooth operation throughout the intended range of motion. • Check instruments with long slender features (particularly rotating instruments) for distortion. • Where instruments form part of a larger assembly, check that devices assemble readily with mating components. • Hinged, rotating, or articulating instruments should be lubricated with a water soluble product (e.g. Instrument Milk or equivalent lubricant) intended for surgical instruments that must be sterilized. Some water-based instrument lubricants contain bacteriostatic agents which are beneficial. Manufacturer’s expiration dates should be adhered to for both stock and use-dilution concentrations.
Step 3
Place prepared cleaning agents in a somication unit. Completely submerge device in cleaning solution and sonicate for 10 minutes at 45-50 kHz.
Processing Category Codes
Step 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 difficult to reach areas.
Step 5
Repeat the sonication and rinse steps above.
Processing codes listed in Table 5. are etched on some instruments and provide information useful in the selection of cleaning agents with appropriate pH. Zimmer recommends that all devices (regardless of etching) are processed in accordance with the manual or combination manual/automated cleaning instructions contained in this reprocessing guide.
Step 6
Remove excess moisture from the instrument with a clean, absorbent and non-shedding wipe.

These devices are tolerant of alkaline cleaning agents when followed by acidic neutralization and thorough rinsing. These devices can be cleaned with rust-removal agents. Cannulations and hollow spaces must be cleaned manually.
Table 3. Combination Manual/Automated Cleaning Steps Step 1
Completely submerge the instruments in enzyme solution and allow to soak for 10 minutes. Use a soft nylon-bristled 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 nylon-bristled brush.
Step 2
Remove devices from the enzyme solution and rinse in purified water for a minimum of 1 minute. Thoroughly and aggressively flush lumens, holes and other difficult to reach areas.
Step 3
Place instruments in a suitable washer/disinfector basket and process through a standard washer/disinfector instrument cycle.
Preparation Before Cleaning • All cleaning agents should be prepared at the use-dilution 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. Note: Fresh cleaning solutions should be prepared when existing solutions become grossly contaminated (bloody and/or turbid).
Table 5. Processing Category Codes
Note: Use of a sonicator at 45-50kHz will aid in thorough cleaning of devices. Note: Use of a syringe or water jet will improve flushing of difficult to reach areas and closely mated surfaces.
