Objective: The aim of this study was to assess the clinical and radiological results of our high tibial osteotomy technique combining f ixator-assisted nailing and subtubercle tibial osteotomy in varus malalignment. Methods: This was a retrospective study of a consecutive series of 32 knees in 32 patients (‘2 follow-up loss’ 12 males and 18 females; mean age at the time of operation: 50.6±7.8 (36–62) years) operated on between 2014 and 2016. Radiographic and clinical measurements were assessed pre- and postoperatively. Kolmogorov-Smirnov, paired t and Wilcoxon rank tests were used in the statistical analyses. Results: The mean follow-up period was 36.1±8.15 (31–53) months, the mean duration of the hospital stay was 3.6±0.1 (2–6) days, and the mean Kellgren-Lawrence score was 2.4±0.6 (2–4). Time to bony union was an average of 16.17 (12–29) weeks. Compared to the preoperative mechanical medial proximal tibial angle, femorotibial angle and mechanical axis deviation measurements, all the postoperative values showed significant changes (p 0.05), and the postoperative Caton-Deschamps index did not show a meaningful change (p>0.05). T he postoperative visual analog scale, Knee Society Score, and Modified Hospital for Special Surgery Knee Scoring System measures showed significant improvement compared to the preoperative values (p<0.01). The postoperative walking distance increased to 1137.50±845.1 meters, from 359.4±306.2 meters (p<0.01). Conclusion: This percutaneous technique is minimally invasive, corrects the alignment in two planes, and does not affect patellar height. We believe that this technique could be a promising alternative to other knee preserving surgeries in correcting varus malalignment.
