Case in brief
A 17-year-old male presented with chronic patellar tendon rupture, characterized by anterior knee pain, instability, and inability to extend the left knee for 2 years. Examination revealed patella alta and a palpable infrapatellar gap. Reconstruction was performed using a peroneus longus autograft in a 4-strand configuration, resulting in restored patellar height and full active extension after one year, with no significant complications.
Diagnostic / clinical pearl
Chronic patellar tendon ruptures with complete tendon loss can be effectively reconstructed using a peroneus longus autograft, which may restore function and patellar height.
