Quadriceps Tendon Ruptures After Total Knee Arthroplasty.

Quadricep tendon (QT) ruptures following total knee arthroplasty (TKA) represent a challenging complication with potentially severe consequences, including impaired function and the need for additional surgical intervention. This article reviews the relevant anatomic features, etiology, and risk factors of QT ruptures after TKA. The different treatment options and indications for nonoperative management, direct repair, augmented repair, extensor reconstruction with mesh, and complete extensor allograft reconstruction are reviewed.
