CT scans were performed pre‐ and post‐operatively to evaluate tibial torsion and valgus/varus deformity. Digital photographs of the ostectomized bone wedges were used to assess divergence of the 2 osteotomies, and the area of the medial and lateral aspects measured to assess osteotomy angulation within the dorsal plane.</p> </sec> <sec id="vsu12228-sec-0005" sec-type="section"> <title>Results</title> <p>Osteotomy divergence angle, the difference between the area of the medial and lateral aspects of the ostectomized wedges, and the difference between the pre‐ and post‐operative angles of valgus/varus deformity were all significantly smaller for the alignment aid group. The difference in pre‐ and post‐operative tibial torsion was not significantly different between groups.</p> </sec> <sec id="vsu12228-sec-0006" sec-type="section"> <title>Conclusions</title> <p>K‐wires can be used successfully as alignment aids during CCWO and help to create a significantly more orthogonal osteotomy. This allows a significant reduction in the difference between the preoperative and postoperative angles of valgus or varus, which may reduce the risk of developing a clinically important iatrogenically introduced valgus/varus deformity postoperatively.</p> </sec> </abstract>
