Tear of Quadriceps and Patellar Tendon with Superior Pole Avulsion of Patella

Abstract

Case: A 58-year-old man presented with right knee pain and inability to extend the knee after falling. magnetic resonance imaging (MRI) demonstrated complete rupture of the quadriceps tendon, avulsion of the superior pole patella, and a high-grade partial tear of the proximal patellar tendon. Surgical dissection revealed that both tendon tears were full-thickness disruptions. Repair was performed without complications. The patient achieved independent ambulation and passive range of motion from 0° to 118° at 3.8 years postoperatively. Conclusions: We present a case of a simultaneous ipsilateral tear of the quadriceps and patellar tendons with superior pole patella avulsion that resulted in a clinically successful repair.
