Abstract： Objective To investigate the correlation between radiographic changes and clinical outcomes after supramalleolar osteotomy （SMOT） for varus ankle osteoarthritis （AA）. Methods A retrospective analysis was conducted on 23 patients （24 feet）with varus AA treated with SMOT between January 2019 and August 2023.There were 9 males （9 feet）and 14 females （15 feet），with a mean age of 57.94 years.Radiographic parameters were compared preoperatively and at final follow-up. Clinical outcomes were assessed using the American Orthopedic Foot and Ankle Society （AOFAS） score and Visual Analogue Scale （VAS） for pain. Correlations between radiographic parameters and AOFAS/VAS scores，as well as between changes in radiographic parameters and final scores，were analyzed. Results The mean folow-up was 15.25±3.07 months. All radiographic parameters，AOFAS，and VAS scores showed significant improvement postoperatively （ P<0.01 ）. The mean AOFAS score were improved to 81.31±2.73，and VAS decreased to 1.93±0.29. Pearson analysis revealed that medial clear space （MCS）was significantly corelated with AOFAS and VAS scores both preoperatively and at final follow-up （ P <0. 05）. Changes in tibial articular surface angle （TAS） and MCS were significantly correlated with clinical outcomes （ P <0. 01）. Conclusion SMOT provides satisfactory mid-term outcomes for varus AA. Changes in TAS and MCS are important indicators for evaluating clinical efficacy，with greater changes associated with beter outcomes.
