The primary indications for performing a medial closing wedge distal femoral osteotomy are valgus knee malalignment, lateral knee compartment overload, lateral meniscus insufficiency, and/or lateral compartment osteoarthritis or cartilage damage. Without correction of this malalignment, there is an increased risk for chondral damage in the lateral and patellofemoral compartment of the knee. The optimal candidates for this procedure are young, active individuals with moderate to severe arthritis in the lateral compartment. Recently, preoperative planning for high tibial and distal femoral osteotomies (HTOs and DFOs) using 3-dimensional (3D) patient-specific instrumentation (PSI) has increased in popularity. Successful patient outcomes have been reported using this technique. This Technical Note illustrates our preferred technique that uses 3D PSI in addition to a patellar OCA transplant when treating a symptomatic cartilage lesion associated with genu valgum.
进行股骨远端内侧闭合楔形截骨术的主要指征是膝外翻畸形、外侧膝关节腔负荷过重、外侧半月板功能不全和/或外侧腔骨关节炎或软骨损伤。如果不纠正这种畸形，膝关节外侧和髌股关节软骨损伤的风险会增加。该手术的最佳候选者是外侧腔患有中度至重度关节炎的年轻、活跃个体。最近，使用三维（3D）患者特异性器械（PSI）进行高位胫骨和股骨远端截骨术（HTO和DFO）的术前规划越来越受欢迎。已有使用该技术取得成功患者治疗效果的报道。本技术说明阐述了我们在治疗与膝外翻相关的有症状软骨损伤时，除使用髌骨OCA移植外还采用3D PSI的首选技术。
