Autologous subchondral bone grafting combined with ACI (sandwich procedure) is a well-accepted procedure for the treatment of osteochondral lesions of the knee. This requires a different surgical technique and preoperative planning. Also pain from bone marrow donor site location is expected and should be part of patient consent and expectations. This study evaluates whether MRI is able to predict the need for a sandwich procedure to help in optimizing the preoperative planning and consent.
