title: Recurrent patella loosening and extra-articular migration after TKA.
abstract: Loosening and subsequent extra-articular migration of the patella component is a rare complication of total knee arthroplasty. We report a case of recurrent aseptic loosening and extra-articular migration of a patella component. Eventually, treatment consisted of removing the patellar component without replacement.
