Coronal limb malalignment is a significant contributor to asymmetric joint wear, gait abnormalities, and the development and progression of degenerative joint disease. Osteotomies about the knee were developed to realign the mechanical axis of the limb to unload the affected compartment. Valgus malalignment is less common than varus malalignment, but can contribute to a variety of clinical conditions, including lateral compartment cartilage defects and arthritis, lateral patellofemoral instability, and medial collateral ligament laxity. In this article, we describe our preferred operative technique for a lateral opening wedge varus-producing distal femoral osteotomy to correct mild to moderate valgus malalignment.
冠状位肢体对线不良是导致关节磨损不对称、步态异常以及退行性关节疾病发生和进展的重要因素。针对膝关节的截骨术旨在重新调整肢体的机械轴，以减轻患侧关节间室的负荷。外翻对线不良比内翻对线不良少见，但可导致多种临床情况，包括外侧间室软骨缺损和关节炎、外侧髌股关节不稳定以及内侧副韧带松弛。在本文中，我们描述了我们首选的手术技术，即外侧开口楔形股骨远端截骨术以纠正轻至中度外翻对线不良。
