Purpose This study aimed to investigate the rate at which patients returned to sports after open wedge high tibial osteotomy and identify the continuity of sports activity post‐operatively. Methods Thirty‐five patients (40 knees) who underwent open‐wedge high tibial osteotomy (OW‐HTO) in medial knee osteoarthritis were included in this study. The mean age of the patients who underwent surgery was 55.1 ± 10.7 years, and the mean follow‐up period was 41.0 ± 24.7 months. Clinical results and radiographic parameters calculated in standing whole‐leg radiographs preoperatively, post‐operatively, and at the final follow‐up were evaluated. Results Thirty‐one patients (88.6%) were able to return to preoperative sports activity; however, only 14 patients (40.0%) completely returned to preoperative sports activity levels. Of the 31 patients who returned to sports activity, 10 patients (32.3%) maintained post‐operative sporting activity levels at the final follow‐up. In radiographic parameters, the weight‐bearing line ratio was considered loss of correction in the post‐operative period leading to the final follow‐up. Patients who completely returned to sports and maintained sporting activity levels at the final follow‐up had significantly higher the Knee Injury and Osteoarthritis Outcome Score pain subscale values and lower visual analogue scale of knee pain at pre‐surgery and final follow‐up than other patients, including those who partially returned to sports. Conclusions The proportion of patients who returned to sports after OW‐HTO and were able to participate in competitions at the same activity level as before surgery was low and insufficient.
