Event Description
|
It was reported that the patient underwent a right knee arthroplasty revision to address post-operative fracture and migration of the articular surface screw as well as pain, swelling and a clicking noise while walking approximately thirty (30) months post-operatively.Initial operative notes noted no intraoperative complications during implantation.Revision operative notes noted that the migrated screw was found anteriorly and was deformed.The articular surface was loose, but the tibial and femoral components were well-fixed.The patellar component appeared to be damaged locally, however, the rest of the component remained undamaged.Scratches were also identified on the femoral component and metal was found in the synovium, requiring a partial synovectomy.When the surgeon opened a new articular surface, the new screw appeared visually longer than the old one, creating suspicion that the screw had fractured.The surgeon was unable to get good fixation with the new articular surface screw and decided intraoperatively to revise the entire construct.No further intraoperative complications were noted.
