Total knee arthroplasty in valgus knee deformities continues to be a challenge for a surgeon. Approximately 10% of patients who undergo total knee arthroplasty have a valgus deformity. While performing total knee arthroplasty in a severe valgus knee, one should aware with the technical aspects of surgical exposure, bone cuts of the distal femur and proximal tibia, medial and lateral ligament balancing, flexion and extension gap balancing, creating an appropriate tibiofemoral joint line, balancing the patellofemoral joint, preserving peroneal nerve function, and selection of the implant regarding constraint. Restoration of neutral mechanical axis and correct ligament balance are important factors for stability and longevity of the prosthesis and for good functional outcome. Thus, our review aims to provide step by step comprehensive knowledge about different surgical techniques for the correction of severe valgus deformity in total knee arthroplasty.
在有内翻畸形的膝关节中进行全膝关节置换术仍然是外科医生面临的一项挑战。大约有 10%接受全膝关节置换术的患者存在内翻畸形。在严重内翻的膝关节中进行全膝关节置换术时，应注意手术暴露、股骨远端和胫骨近端的截骨、内外侧韧带平衡、屈伸间隙平衡、形成合适的胫股关节线、髌股关节平衡、保护腓总神经功能以及假体约束的选择等技术方面。恢复机械力学轴的中立和正确的韧带平衡是假体稳定性和寿命以及良好功能结果的重要因素。因此，我们的综述旨在提供关于在全膝关节置换术中矫正严重内翻畸形的不同手术技术的全面知识。
