Assessment of cartilage regeneration in initial and second-look arthroscopy following low tibial osteotomy for varus osteoarthritis of the ankle

Second-look arthroscopy after low tibial osteotomy revealed good cartilage repair in the medial gutter, but it was poor in the anteromedial talar dome and associated with persistent postoperative pain. A large pre- and postoperative TMMA and medial deviation of the postoperative axis of loading may inhibit cartilage repair in these patients.
