Radiographs and MRI revealed a partial distal patellar tendon avulsion injury, a complete tear of the ACL, and associated bone bruises on the lateral femoral condyle, and also on the posterolateral tibial plateau (Figures 1-3).
The patient also underwent magnetic resonance imaging (MRI) of the knee, which confirmed the distal patellar tendon avulsion, and demonstrated a complete tear of the anterior cruciate ligament (ACL), associated bone bruises on the lateral femoral condyle, and also on the posterolateral tibial plateau. The posterior cruciate ligament and the MCL were undamaged.

Lateral radiographic view of the knee at a 9-month follow-up. Radiographs demonstrated a normal patellar height with a Caton-Deschamps index measured at 0.7; however, we noted an anterior static tibial translation of 9 mm.

At a 9-month follow-up (Figure 4), the patient recovered a functional range of motion, with a mild 20  flexion restriction.
