Additional Manufacturer Narrative

NO DEVICE ASSOCIATED WITH THIS REPORT WAS RECEIVED FOR EXAMINATION, HOWEVER X-RAY REVIEW CONFIRMS TIBIAL TRAY LOOSENING AT THE CEMENT/IMPLANT INTERFACE. A WORLDWIDE LOT SPECIFIC COMPLAINT DATABASE SEARCH, OR DEVICE HISTORY RECORD (DHR) REVIEW WAS NOT POSSIBLE BECAUSE THE REQUIRED LOT CODE(S) WAS NOT PROVIDED. BASED ON PREVIOUS INVESTIGATIONS THIS COMPLICATION OF JOINT REPLACEMENT IS UNLIKELY TO HAVE BEEN THE RESULT OF A DEVICE FAILING TO MEET REQUIRED SPECIFICATIONS. THE INFORMATION RECEIVED WILL BE RETAINED FOR POTENTIAL SERIES INVESTIGATIONS IF TRIGGERED BY TREND ANALYSIS, POST MARKET SURVEILLANCE, OR OTHER EVENTS WITHIN THE QUALITY SYSTEM. CORRECTIVE ACTION WAS NOT INDICATED. DEPUY CONSIDERS THE INVESTIGATION CLOSED AT THIS TIME. SHOULD THE ADDITIONAL INFORMATION BE RECEIVED, THE INFORMATION WILL BE REVIEWED AND THE INVESTIGATION WILL BE RE-OPENED AS NECESSARY.
