Quadriceps Rupture Associated with a Proximal Quadriceps Release in Total Knee Arthroplasty

Complex primary and revision total knee arthroplasties often require extensile surgical approaches. The problems of scarring, stiffness, and distorted anatomy add to the challenges of reconstructing osseous defects and stabilizing the implant. Wide surgical exposure is clearly required to achieve a well-functioning prosthesis, but the benefits of such an approach must be weighed against the risk of complications.
