Delayed repair of the quadriceps using the Mitek anchor system: a case report and review of the literature.

Extensor mechanism disruptions are relatively uncommon knee injuries. Within this group, delayed treatment is an infrequent but difficult clinical situation. Fibrous degeneration, muscle contraction and subsequent hiatus present a challenge to the orthopaedic surgeon. We present an unusual case of a successful delayed repair using the Mitek anchors system (Mitek Products Inc., a division of Ethicon Inc., Westwood, Massachusetts).
