[Complete rupture of the proximal semimembranosus tendon. Minimally invasive surgical repair by use of a suture anchor in a rare but often underestimated injury].

Complete rupture of the proximal semimembranosus tendon is a rare injury associated with significant functional loss. Conservative treatment has proven inadequate in returning patients to their previous activity level. However, diagnosis is often delayed because of underestimation of the severity of this injury. Satisfactory results can be achieved with both early and late surgical tendon repair in the majority of cases. However, repair delayed by more than 4 weeks post trauma usually requires extended mobilisation of the injured muscle and neurolysis of the sciatic nerve. Therefore, we recommend surgical repair as early as possible. We report on the successful minimally invasive surgical repair of a complete rupture of the proximal semimembranosus tendon by use of a suture anchor 18 days after injury.
