Classically, hip capsule tears are treated with surgical repair; however, there may be a role for less invasive therapies in select patients with certain occult hip capsular injuries. This particular study involved a 27-year old male professional soccer player who developed heterotopic ossification of the hip casule, and gluteus minimus tendon after an arthroscopic hip procedure.
After removal of the heterotopic bone, the patient had a symptomatic deﬁciency of his hip capsule and gluteus minimus tendon. A series of orthobiologic treatments with platelet-rich plasma and bone marrow aspirate concentrate improved the patient’s pain and strength as well as the morphologic appearance of the hip capsule and gluteus minimus tendon on magnetic resonance imaging.
Platelet-rich plasma contains a high concentration of platelets, growth factors and cytokines necessary for cell differentiation and tissue healing. Independent use of these biologic therapies has been reported to result in improvement in the mechanical properties and histologic appearance of some musculoskeletal tissues.
