Complete rupture of the distal semimembranosus complex in a professional athlete.

Complete ruptures of the distal hamstring tendons rarely cause functional disability significant enough to warrant surgical intervention. Isolated ruptures of the distal semimembranosus tendon complex have not been reported previously in the literature. A case of a complete rupture of the distal semimembranosus tendon complex occurring in a professional football player with resultant functional disability is reported here. The magnetic resonance imaging scan was essential for an accurate diagnosis. Subsequent surgical repair and postoperative rehabilitation is described. Strict attention to recreating the multiple attachments of the semimembranosus tendon complex is recommended.
