Regeneration of the semitendinosus and gracilis tendons following their transection for repair of the anterior cruciate ligament

Abstract

Apparent regeneration of the tendons of the semiten dinosus and gracilis muscles after their use for anterior cruciate ligament reconstruction was noted during rou tine followup of 225 patients. From this group, four patients were selected for thorough examination, in cluding magnetic resonance imaging, electromyo graphic studies, strength testing, and clinical examina tion. The results demonstrate that these tendons ap pear to regrow and are probably functional.
