Painful hip snapping can present as a rare sequela of proximal hamstring injury. We present a case of painful snapping of the conjoint tendon of the semitendinosus and biceps femoris over the ischial tuberosity in the setting of a partial proximal hamstring disruption. Dynamic ultrasonography identified the source of snapping and a persistent attachment of the conjoint tendon to the sacrotuberous ligament, which prevented retraction and allowed subluxation of the tendons across the ischial tuberosity. Following surgical transection of the persistent sacrotuberous ligament attachment to the conjoint tendon and tendon reattachment, the patient's symptoms resolved with full return of function.
