THE DEVICE ASSOCIATED WITH THIS REPORT WAS NOT RETURNED. REQUESTS FOR ADDITIONAL INVESTIGATIONAL INPUTS WERE MADE IN ACCORDANCE WITH WI-7915 APPENDIX A. PATIENT MEDICAL RECORDS AND X-RAYS WERE PROVIDED. REVIEW OF THE SUPPLIED INVESTIGATIONAL INPUTS CONFIRMED OSTEOLYSIS AND LOOSENING OF THE FEMORAL AND TIBIAL COMPONENT. REVIEW OF THE DEVICE HISTORY RECORDS AND/OR A COMPLAINT DATABASE SEARCH WAS NOT POSSIBLE AS THE PRODUCT AND LOT CODES REQUIRED WERE NOT PROVIDED. THE INVESTIGATION COULD NOT DRAW ANY CONCLUSIONS ABOUT THE ROOT CAUSE OF THE OSTEOLYSIS OR THE LOOSENED FEMORAL AND TIBIAL COMPONENT BASED ON THE PROVIDED INFORMATION. BASED ON THE INABILITY TO DETERMINE A ROOT CAUSE, THE NEED FOR CORRECTIVE ACTION WAS NOT INDICATED. DEPUY CONSIDERS THE INVESTIGATION CLOSED AT THIS TIME. SHOULD ADDITIONAL INFORMATION BE RECEIVED, THE INFORMATION WILL BE REVIEWED AND THE INVESTIGATION WILL BE RE-OPENED AS NECESSARY.
