FAI February 2025 Podcast: Correction Target of Supramalleolar Osteotomy for Early Varus Ankle Arthritis: Is Overcorrection Necessary?
Update: 2025-02-10
Description
The aim of this study was to investigate the clinical and radiologic outcomes following supramalleolar osteotomy for early varus ankle arthritis with the medial translation of the talus, wherein the lateral translation of the talus center to the tibial axis was used as a correction target. Another aim was to compare the results between the ankles with a normal range of medial distal tibial angle (MDTA) and overcorrected MDTA at the postoperative period to investigate the role of overcorrected MDTA after the supramalleolar osteotomy.
In conclusion, lateral translation of the talus center relative to the tibial axis can be used as a correction target for medial opening supramalleolar osteotomy to treat early varus ankle arthritis with medial translation of the talus. Overcorrection of the tibial plafond to valgus does not seem necessary.
