Reports come from manufacturers, hospitals and patients and are not verified by the FDA. A report does not prove the device caused the event. Widely used products collect more reports, so totals can't be used to compare products or estimate failure rates. Only reports that name a model's exact device identifier are counted.

• InjuryJul 27, 2026Adverse Event Without Identified Device or Use Problem

  It was reported that the patient presented post revision total knee arthroplasty with an improperly tracking patella. Femoral components was exchanged to a smaller femur, thus shortening overall the distance of the construct and creating less tension on her quadriceps mechanism. A lateral release was also performed in conjunction with an extensive repair or her medial tissues. This resulted in a better tracking patellar and should result in more proper function. LPS Adapter had been placed on (b)(6) 2026 and LPS distal femur and insert had been placed on (b)(6) 2026. No allegation was made against any component. The patella implant but was well fixed and left in place.DOI: (b)(6) 2026.DOR: (b)(6) 2026.Affected side: Right knee.

SURGEON IS NOT SURE WHY PATIENT IS SO STIFF AS NO INFECTION IS PRESENT BASED ON LABS AND FROZEN SECTION. ALL COMPONENTS WERE REMOVED. FEMORAL SLEEVE WAS NOT INGROWN ALMOST 5 MONTHS POST OP. THERE WAS NO RADIOGRAPHIC INDICATION THAT COMPONENT WOULD BE LOOSE. TIBIAL COMPONENTS WERE SUBSEQUENTLY REMOVED TO LOWER THE JOINT LINE AS THE PATELLA WAS IMPINGING THE INSERT AFTER REVISING THE FEMUR. THIS IS LIKELY A RESULT OF SHORTENING OF THE PATELLAR TENDON DUE TO LACK OF MOTION. TIBIAL SLEEVE WAS ONLY PARTIALLY INGROWN. NO DELAY NOR PATIENT HARM WAS NOTED. DOI: (B)(6) 2025. DOR: (B)(6) 2025.

ALL COMPONENTS WERE WELL FIXED BUT LACK OF BONY INGROWTH ALSO SUGGESTS PERSISTENT INFECTION. AN I&D WAS PERFORMED ON (B)(6) 2025, WHERE THE POLY AND PIN WERE REPLACED.
