Reconstruction of chronic patellar tendon rupture with semitendinosus tendon: case report.

Chronic patellar tendon rupture is a rare injury whose treatment poses technical difficulties. Surgical repair is mandatory to restore the extensor mechanism of the knee. Many different surgical methods of patellar tendon reconstruction have been described. We present the case of a 48-year-old male patient who sustained patellar tendon rupture 8 months before surgery. A semitendinosus tendon graft and the modified Ecker technique were used for the reconstruction of the patellar tendon. Full extension was achieved alongside high patient satisfaction. However, the patient required prolonged intensive rehabilitation.
