Arthroscopic Treatment of Popliteal Tendon Impingement Following TotalKnee Arthroplasty: A Case Report

The popliteal tendon has been known to catch over a femoral osteophyte or the overhanging edge of the femoral component very occasionally following total knee arthroplasty (TKA). However, impingement of the popliteal tendon against the posterior edge of the tibial liner is rare. Although its pathological mechanism is simple, this complication cannot be definitively diagnosed unless posterior arthroscopic examination is performed. In this report, we describe the diagnostic and treatment challenges of using arthroscopy via posteromedial and posterolateral portals.
