Heterotopic ossification is the abnormal formation of mature, lamellar bone in nonosseous tissue such as tendons, ligaments, muscles, and soft tissue. We discuss a rare case of a young adolescent with patellar tendon rupture postheterotopic ossification. A 13-year-old male presented to us with knee pain and inability to extend for 6 weeks following trivial trauma. Preliminary radiological investigations revealed a high riding patella with ossification in the patella tendon. The magnetic resonance scan confirmed the same with patellar tendon disruption and heterogeneous ossification. He underwent surgery with patella tendon repair, augmentation with autograft, and had complete recovery at 6 months' follow-up.
Keywords: adolescent; heterotopic ossification; patellar tendon; rupture.
