Surgical Technique: Arthroscopic Microfracture of Acetabular Articular Cartilage Lesions
Acetabular articular cartilage lesions can occur as a result of femoroacetabular impingement, traumatic subluxation or dislocation, labral tears, loose bodies, osteonecrosis, osteochondritis dessicans, slipped capital femoral epiphysis, hip dysplasia, or early degenerative joint disease. Cartilage lesions cause significant morbidity, particularly in athletes and active patients. Microfracture techniques in the setting of hip arthroscopy have been developed recently. The ideal patient is a young (<50–60 years old), active patient willing to follow the postoperative rehabilitation protocol. The ideal lesion to treat with microfracture is well contained, focal (<2–4 cm), Outerbridge grade IV, and with intact subchondral bone. Surgical outcomes in small case series have shown promising clinical outcomes.
