N2 - Purpose: We aimed to describe the radiographic, functional, and patient-reported outcomes (PROs) of medial femoral trochlea osteochondral free flap reconstruction of the proximal lunate in stage IIIA and IIIB Kienböck disease. Methods: Eighteen adult patients underwent medial femoral trochlea reconstruction of the proximal lunate for advanced Kienböck disease by a single surgeon. Eight of these patients returned for clinical examination, radiographs, and completion of PRO questionnaires. An additional 4 patients completed PRO questionnaires remotely. Results: The mean patient age was 28.4 years. The mean radiographic and physical examination follow-up was 1.4 and 2.2 years, respectively. The mean PRO follow-up was 2.1 years. Radiographic measurements (carpal height ratio, radioscaphoid angle) demonstrated that carpal collapse was halted, and carpal alignment was maintained, after surgery. Wrist flexion (38.3°) and extension (37.3°) were unchanged by this operation, and postoperative pinch and grip strength were 90% and 68% of the uninjured side, respectively. The mean postoperative Disabilities of the Arm, Shoulder, and Hand score was 10.8, and the Patient-Rated Wrist Evaluation score was 18.1. Knee Injury and Osteoarthritis Outcomes Score subscales, International Knee Documentation Committee, and Kujala lower extremity PRO scores ranged from 83.1 to 96.8. The Patient-Reported Outcomes Measurement Information System Global Health, Physical Function, Pain Intensity, Pain Interference, and Pain Behavior scores reflected good postoperative patient health and function and low pain levels. Conclusions: Following medial femoral trochlea reconstruction of the proximal lunate for advanced Kienböck disease, we observed a cessation of radiocarpal collapse. After surgery, patients demonstrated acceptable levels of function, pain, and wrist range of motion. Type of study/level of evidence: Therapeutic V.
