Patellar dislocation is a well-recognized major complication after total knee arthroplasty (TKA). Treatment of this injury is determined according to the cause of the dislocation. In particular, proximal realignment, distal realignment, and lateral retinaculum release are options if patellar instability is not caused by prosthetic malposition. Here we report a case of patellar dislocation following TKA due to rupture of the medial structures that was treated by medial patellofemoral ligament reconstruction and lateral retinacular release. In addition, we provide a brief review of the related literature. J. Med. Invest. 61: 409-412, August, 2014
