Traditionally, correction of femoral deformity has been performed with osteotomies through the center of rotation of angulation (CORA), but the CORA location is not always practical. If the osteotomy is created at a site adjacent to the CORA, an additional translation must be performed to accurately correct the deformity. However, at times, the ideal osteotomy site may require an unfeasible amount of translation. Multiple osteotomies may also be problematic, and when overcorrection of the mechanical axis is planned, the CORA method is not practical.This article describes a novel method by which the surgeon may choose the location of the osteotomy regardless of the location of the CORA and may consolidate a multiapical deformity into a single corrective osteotomy. Furthermore, intentional mechanical axis overcorrection may be performed to unload knee joint arthritis. Simple, complex, and multiapical deformities may now be corrected via a single familiar surgical procedure, such as a distal femoral osteotomy, and the need for translation is eliminated.
传统上，股骨畸形的矫正通过经成角旋转中心（CORA）进行截骨术来完成，但CORA的位置并不总是可行的。如果在与CORA相邻的部位进行截骨术，则必须进行额外的平移才能准确矫正畸形。然而，有时理想的截骨部位可能需要不可行的平移量。多次截骨术也可能存在问题，并且当计划对机械轴进行过度矫正时，CORA方法并不实用。本文描述了一种新方法，通过该方法外科医生可以选择截骨部位，而无需考虑CORA的位置，并且可以将多顶点畸形合并为单一的矫正截骨术。此外，可以有意进行机械轴过度矫正以减轻膝关节关节炎。现在，简单、复杂和多顶点畸形都可以通过单一熟悉的外科手术（如股骨远端截骨术）进行矫正，并且消除了平移的需要。
