Arthroscopic and Endoscopic Treatment of Proximal Rectus Femoris Avulsion.

Proximal rectus femoris avulsion (PRFA) is an uncommon injury that is poorly reported in the literature. Historically, these injuries have been treated nonoperatively or with open techniques. This is the first study showing endoscopic treatment of this injury. We present a systematic review of PRFA treatment and a case report of a patient whose injury was treated endoscopically. Sixty-four injuries were reported across several sports. Patients underwent nonoperative management, suture repair, suture anchor repair, or excision of the tendon stump. Surgical complications included lateral femoral cutaneous nerve injury and wound complications. The patient who underwent arthroscopic treatment had a good outcome. [Orthopedics. 2022;45(1):e1-e6.].
