THE SWAGING PROCESS IS VALIDATED PER THE SUPPLIER TO PRODUCE A CONFORMING SWAGED HOLE DIAMETER. THE CAUSE OF THE MISSING COMPONENT IS UNK. EVAL: VISUAL EXAMINATION IDENTIFIED MISSING SUB- COMPONENTS FROM PERSONA TIBAL ARTICULAR SURFACE PROVISIONAL 5/14/14 Malfunction THE SWAGED HOLE. Manufacturer Narrative: COMPATIBILITY WAS VERIFIED WITH NO ISSUES NOTED. THE PATTERN OF WEAR SUGGESTS IMPROPER ALIGNMENT. RADIOGRAPHS WERE NOT RETURNED FOR REVIEW; THEREFORE; ALIGNMENT CANNOT BE VERIFIED. CAUSE CANNOT BE DEFINITIVELY DETERMINED WITH THE INFORMATION PROVIDED. DEVICE HISTORY RECORDS WERE REVEILED AND FOUND TO BE CONFORMING. VISUAL EXAMINATION OF THE RETURNED ARTICULAR SURFACE REVEALED WEAR DAMAGE TO THE POSTERIOR ASPECT OF THE MEDIAL CONDYLE ON THE ARTICULATING SURFACE. THERE IS ALSO WEAR DAMAGE ON THE POSTEROLATERAL EDGE NEAR THE SUPERIOR SURFACE OF THE POSTERIOR STABILIZING SPINE. NO OTHER DAMAGE WAS IDENTIFIED.

Event Description: IT IS REPORTED THAT THE ARTICULAR SURFACE DID NOT LOCK SECURELY ON TO THE TIBIAL PLATE. Manufacturer Narrative: EVAL SUMMARY: IT IS LIKELY THAT THE PROBLEMS ENCOUNTERED ARE RELATED TO SURGICAL TECHNIQUE. NO OTHER COMPLAINT OF THIS NATURE HAVE BEEN RECEIVED FOR THIS PRODUCT/LOT COMBINATION AND NO OTHER COMPLAINTS OF THIS NATURE HAVE BEEN RECEIVED FROM THIS SURGEON. THE DEVICE HISTORY RECORDS WERE REVIEWED AND FOUND CONFORMING. DIMENSION MEASURE FOUND THE PART TO BE CONFORMING TO PRINT SPECS. VISUAL EXAMINATION IDENTIFIED THAT THE DOVETAIL FEATURE WAS COMPRESSED DOWN BOTH SIDES; INDICATING THAT THE ARTICULAR SURFACE WAS NOT CORRECTLY PLACED AND ORIENTED BEFORE PUSHING IT USING THE INSERTER INSTRUMENT.

THE 10 MM POLY WOULD NOT LOCK INTO THE TRAY. THE SURGEON WAS FINALLY ABLE TO GET THE 11 MM POLY MOST OF THE WAY DOWN. Manufacturer Narrative: A PICTURE OF AN AP RADIOGRAPH WAS RECEIVED; HOWEVER; DIMENSIONAL ANALYSIS WAS INCONCLUSIVE DUE TO THE POOR QUALITY OF THE PHOTOGRAPH. IT IS LIKELY THAT THE PROBLEMS ENCOUNTERED ARE RELATED TO SURGICAL TECHNIQUE. DEVICE HISTORY RECORDS WERE REVIEWED AND FOUND TO BE CONFORMING. VISUAL EXAMINATION OF THE RETURNED ARTICULAR SURFACE CONFIRMS THE CENTRAL ASPECT OF THE LOCKING DOVETAIL IS COMPRESSED; THE TRACKS ON THE INTERNAL ASPECT ARE SEVERELY DEFORMED; THE TRACKS ON THE EXTERNAL ASPECT ARE ONLY SIGNIFICANTLY DAMAGED ON THE MEDIAL SIDE; AND THERE IS SIGNIFICANT DAMAGE TO THE ANTERIOR ASPECT OF THE ARTICULAR SURFACE CONSISTENT WITH ATTEMPTS TO IMPACT THE COMPONENT. IN THE CASE WHERE THE TIBIAL COMPONENT WAS A SMALLER SIZE; IT WOULD BE EXPECTED THAT BOTH SIDES OF THE EXTERNAL DOVETAIL TRACK WOULD BE DAMAGED ON THE POSTERIOR ASPECT. THE DAMAGE TO THE DOVETAIL TRACKS IS INDICATIVE OF IMPROPER 3/4/14 Malfunction ALIGNMENT DURING INSERTION. Event Description: IT IS REPORTED THAT THE PATIENT IS EXPERIENCING PAIN. THE PATIENT IS ALSO REPORTED A POSSIBLE INFECTION AND HAS NEVER FELT THE INCISION HEALED. Manufacturer Narrative: PRIMARY OPERATIVE NOTES STATE THE KNEE CAME TO FULL FLEXION AND EXTENSION WITH STABILITY AT MID FLEXION.
