Surgical Repair of Distal Rectus Femoris Myotendinous Rupture

Background Distal rectus femoris ruptures result from a noncontact injury in which the quadriceps contracts with the knee in a flexed position. Risk factors for rectus femoris rupture include systemic processes, such as obesity, gout, diabetes mellitus, chronic renal failure, hyperparathyroidism, and prolonged steroid intake; however, the primary cause of traumatic distal rectus femoris rupture is repetitive microtrauma in the tendon from participation in strenuous sports activities. Expedient diagnosis and surgical management are critical to optimize outcomes and restore knee function. Purpose This video demonstrates a technique for surgical repair of a rectus femoris rupture. Methods An overview of the pathogenesis, diagnosis, and management of rectus femoris ruptures is discussed. The case presentation of a 23-year-old man with a distal rectus femoris myotendinous rupture is discussed. The patient underwent surgical repair. Results The procedure was successfully performed, and rectus femoris anatomy was restored. The patient was advanced through a standardized rehabilitation protocol. At a follow-up of 6 weeks, the patient’s function had substantially improved. The patient denied any recurrence or sensation of instability. The patient was progressing toward his goal of returning to full functional capacity, including sports activity. Conclusion Surgical repair is a reliable treatment option for patients with an acute rectus femoris rupture. Early results suggest good to excellent radiographic and clinical outcomes.
