Varus malalignment of the ankle may be a misleading term. The isolated frontal plane deformity has been shown to be multiplanar in nature. Identifying this dominant feature of the condition and applying appropriate surgical principles to allow for complete correction of the deformity are critical to a successful outcome. The following 3 factors are key to an optimal surgical outcome from TAR with VMAA: (1) Obtaining a congruent ankle with sufficient ROM is a important before implantation of the arthroplasty prosthesis; (2) not all ankles are correctable; and (3) recognition both preoperatively and intraoperatively that a conversion of TAR to a fusion is sometimes the best course of action to achieve best results or patient satisfaction.
踝关节内翻畸形可能是一个容易引起误解的术语。已表明孤立的额面畸形本质上是多平面的。识别该病症的这一主要特征并应用适当的手术原则以实现畸形的完全矫正对于成功的手术结果至关重要。对于伴有VMAA的距骨全踝关节置换术，以下3个因素是实现最佳手术结果的关键：（1）在植入关节置换假体之前获得具有足够活动度的 congruent 踝关节很重要；（2）并非所有踝关节都可矫正；（3）术前和术中都认识到将距骨全踝关节置换术转换为融合术有时是实现最佳结果或患者满意度的最佳行动方案。
