Rare and often underestimated: A literature review and case report of isolated, proximal semimembranosus injury

Abstract

Isolated and Retracted avulsion of the proximal semimembranosus tendon is exceedingly rare. Current literature suggests that most hamstring tears involving only one of the three muscles can be managed with conservative treatment. However, the semimembranosus contributes significantly to the strength and flexibility of the hamstring and even isolated tears may lead to long term consequences. We present a literature review and case report of isolated, proximal semimembranosus tears. Especially in the case of an elite athlete, such as an NCAA American football player presented here, a retracted, proximal semimembranosus avulsion may require surgical management to ensure return of strength, speed, and flexibility that will allow this athlete to continue to compete.
