Osteochondral Autograft Transplantation for Proximal Lunate Articular Defects.

BACKGROUND: No consensus treatment option for focal osteochondral defects of the proximal lunate exist in the literature. Surgical management has thus far been limited to salvage procedures such as proximal row carpectomy and partial arthrodesis. CASE DESCRIPTION: We report our experience using the osteochondral autograft transplantation surgery (OATS) procedure in two young, active patients with focal osteochondral defects of the proximal lunate. At mean follow-up of 6 years, sustained improvements in pain, motion, and function were observed. Both patients reported high levels of satisfaction and neither experienced any complications. LITERATURE REVIEW: To our knowledge, this is the first report describing the use of OATS to treat proximal lunate defects. CLINICAL RELEVANCE: OATS is a valuable surgical option for treating focal chondral defects of the proximal lunate, with positive outcomes at greater than 5 years postoperatively. This may be an especially useful technique for younger, active patients, and those wishing to maintain maximum functionality.
