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.
