Isolated rupture of biceps femoris tendon

Authors present a case of rupture of the distal end of the biceps femoris. Injuries at this site are relatively rare. Clinical assessment can be aided by instrumental examinations such as ultrasound and especially NMR. Delayed treatment because of erroneous diagnosis or failure of conservative therapy can result in proximal retraction and atrophy of the muscle belly, requiring more complex surgery. Despite the limited data in the literature, Authors favor immediate surgical treatment of both complete and partial injury of the biceps femoris tendon, particularly in a patient who requires a high level of function.
