The semitendinosus and gracilis tendons regenerated in the majority of patients and regained an almost normal point of insertion on the pes anserinus a minimum of 6 years after harvest. The regenerated tendons had a cross-sectional area similar to that on the nonoperated contralateral side. The patients revealed a strength deficit in deep knee flexion but not in internal rotation.
