After isolated ankle (tibiotalar) arthrodesis, the triceps progressively shifts the subtalar joint into varus thus blocking compensatory motion from the midtarsal joints. In a tibiotalocalcaneal arthrodesis, the subtalar may be fixed with the correct valgus. Comparison between ankle and tibiotalocalcaneal arthrodesis does not clearly favor one over another for pain relief, satisfaction, and gait analysis. Compensatory sagittal plane motion through the midtarsal joints when the subtalar is fixed in valgus may be responsible for these results. Tibiotalocalcaneal arthrodesis has become our procedure of choice over isolated tibiotalar for end-stage ankle arthritis regardless of the radiographic state of the subtalar.
孤立性踝（距下）关节融合术后，三头肌逐渐将距下关节推向内翻，从而阻止从中跗关节的代偿运动。在跟距跟舟关节融合术中，距下关节可以用正确的外翻位固定。踝关节和跟距跟舟关节融合术在缓解疼痛、满意度和步态分析方面的比较并没有明显偏向于其中任何一种。当距下关节固定在外翻位时，通过中跗关节的代偿矢状面运动可能是这些结果的原因。无论距下关节的影像学状态如何，跟距跟舟关节融合术已成为我们治疗晚期踝关节关节炎的首选方法，而非孤立性踝距下关节融合术。
