He underwent rehabilitation with rapid resolution of his presenting pain but frequent intermittent recurrence of anterior thigh pain. After he was provided a definitive diagnosis with musculoskeletal ultrasound, he underwent an extended period of rehabilitation and eventually experienced complete recovery without recurrence.<\/jats:p><\/jats:sec><jats:sec><jats:title>Differential Diagnosis<\/jats:title><jats:p>Rectus femoris avulsion, rectus femoris strain or partial tear, inguinal hernia, or acetabular labral tear.<\/jats:p><\/jats:sec><jats:sec><jats:title>Treatment<\/jats:title><jats:p>Operative and nonoperative options were discussed.
