We report 2 cases of ipsilateral ankle and knee osteoarthritis (OA), with the chief complaint being chronic ankle and knee pain. In the first patient, the ankle pain was more severe than the knee pain, whereas the second patient had more severe pain in the knee than in the ankle. In both cases, varus malalignment of the knee and varus tilt of the ankle joint were detected on standing radiographs. The severity of OA was found to be grade 4 in the knee, according to the Kellgren-Lawrence grading system, and stage IIIa in the ankle, according to the modified Takakura ankle OA classification system. Navigation-assisted total knee arthroplasty was performed in both cases, leading to a decreased degree of varus malalignment in the knee and ankle, as well as a significantly improved patient-based outcome in both joints. Correction of malalignment of the ankle by total knee arthroplasty relieved the severe pain and restored optimal function in the ankle without surgical intervention.
我们报告2例同侧踝关节和膝关节骨关节炎（OA），主要症状为慢性踝关节和膝关节疼痛。第一例患者，踝关节疼痛比膝关节疼痛更严重，而第二例患者膝关节疼痛比踝关节疼痛更严重。在这两例中，站立位X线片均显示膝关节内翻畸形和踝关节内翻倾斜。根据Kellgren-Lawrence分级系统，膝关节OA严重程度为4级，根据改良Takakura踝关节OA分类系统，踝关节为IIIa期。两例均行导航辅助全膝关节置换术，导致膝关节和踝关节内翻畸形程度减轻，且两个关节基于患者的结局均显著改善。通过全膝关节置换术矫正踝关节畸形，无需手术干预即可缓解踝关节剧痛并恢复最佳功能。
