title: Failed regrowth of the harvested semitendinosus tendon: a rare complication of tendon harvest after anterior cruciate ligament reconstruction.
abstract: Harvested hamstring tendons were recently shown to possess the ability to regrow and regain their function in flexing the knee joint. In this study, we report a case of failed regrowth of previously harvested semitendinosus tendon to its original insertion site in a 24-year-old professional soccer player. The disturbance resulted in the formation of a clearly visible Popeye-type muscular prominence in the proximal thigh and a notable gap in the midthigh distal to the muscular prominence in knee flexion. Furthermore, 6 months after surgery, in the second full-speed soccer practice, the patient experienced a sudden sharp pain in his hamstring muscles, which was later diagnosed as being from a strain of the semitendinosus muscle.
