title: Quadriceps tendon impingement from a femoral interference screw.
abstract: Interference screws are a popular method of securing tendon grafts during anterior cruciate ligament reconstruction. This report describes the case of a patient with anterior knee pain, limited flexion, and partial-thickness tear of the quadriceps tendon caused by a protruding femoral interference screw following hamstring tendon anterior cruciate ligament reconstruction. The interference screw was radiolucent, requiring magnetic resonance imaging to visualize its location. Removal of the protruding portion of the interference screw and debridement of the partial-thickness tear of the quadriceps tendon led to rapid restoration of knee flexion and alleviation of the anterior knee pain.
