This report describes a case of low tibial osteotomy (LTO) for varus-type osteoarthritis of the bilateral ankles. The patient was a 53 year-old woman with pain, swelling and varus deformity of the bilateral ankles. Tests for rheumatoid arthritis were negative, and the final diagnosis was varus-type osteoarthritis of the bilateral ankles. Conservative therapy was not able to improve her symptoms. From the radiological findings, the osteoarthritis of the ankles was classified as intermediate stage. At first, we performed a left LTO with an opening wedge osteotomy. We aimed to achieve a TAS angle of 94° and a TLS angle of 80°. After nine months, we performed a right LTO using a locking plate. The short-term results have shown good alignment correction and bony fusion. Absence of ankle pain was achieved and there was improvement of ankle motion. Initial stability could be acquired by using a locking plate, and positive rehabilitation was able to be performed from the early stage.
