A 21-year-old NCAA Division 1 Lacrosse player presented to the training room with right anterior thigh pain of 4-5 weeks duration. Onset was gradual, occurring in the spring lacrosse season and starting during training and practice. She did not report any new activity or specific mechanism of injury leading to the pain. She had no history of surgery or major injury to the region. She had previously been seen by the athletic trainer at the onset of pain, described initially as a soreness in her anterior thigh of gradual onset at practice, and started on conservative management for a presumed quadriceps strain. This initial management consisted of modified activities at practice, rehabilitation therapy in the training room, NSAIDS, ice, cupping, and needling. Despite some initial improvement with these treatments, symptoms increased with gradual return to lacrosse. The pain was now throbbing, worse after games, occurring at night, waking her up from sleep, and exacerbated when her leg would hang over the edge of the chair. On exam, she had full active and passive range of motion and strength of the hip as well as the knee. She had tenderness over the right anterior mid-proximal thigh, extending over and area of approximately 10 cm. The tenderness was worse medially than laterally with no palpable defect in the muscle, and she had a positive fulcrum and hop test. Her neurovascular exam was intact. An X-ray of the femur did not reveal any abnormalities. An MRI was ordered to rule out a stress fracture and to evaluate the quadriceps muscle further. The MRI showed an acute complete disruption of the inner bipennate muscular component of the right rectus femoris from the more superficial unipennate muscular component with retraction of the inner component, consistent with an acute degloving injury. No abnormality was noted in the osseous structure. These findings are highlighted in Figures 1 and 2. Given these findings of a closed degloving injury of the rectus femoris, the decision was made to discontinue all lacrosse activities and start a period of rest. After 2 weeks of rest with only a gentle range of motion exercises, her pain had improved. She progressed through therapy conservatively as the lacrosse season had just ended, starting with isometrics, and then progressing as tolerated to dynamic exercises followed by lacrosse-specific drills and exercise. By six weeks (42 days), she felt great and was cleared for full activity in therapy/progression to sport with estimated return to full competition at eight weeks (56 days) had it not been the offseason. The patient was able to participate in all offseason activities and had no setbacks or recurrence of symptoms the following season, returning fully to the level of play prior to injury.
