A 58-year-old male patient. The preoperative anterior-posterior view (a) and Saltzman view (b) showed stage 3a varus ankle osteoarthritis. The preoperative talar tilt angle was 14.3°. The patient was treated with supramalleolar osteotomy and modified Brostrom procedures. The 1-year postoperative scans showed that the alignment was better than that of the preoperative conditions, the functional outcomes were improved, and the modified Takakura stage was improved to stage 2 (c, d), but the talar tilt angle was still larger than normal (6.4°)
