Supramalleolar osteotomies for correction of posttraumatic varus arthritis in early and mid-stages provide good functional and clinical outcomes. However, the biomechanical behavior of the ankle joint differs from the knee, and therefore correction of the distal TAS angle alone may not provide a physiologic load transfer across the ankle joint. Osseous balancing of an arthritic varus ankle joint may require not only correction of the articular surface angle in the frontal plane but may include a biplanar correction to improve the talar coverage and a fibular osteotomy to restore ankle joint congruency.
用于矫正早中期创伤后内翻性关节炎的踝关节上截骨术可提供良好的功能和临床效果。然而，踝关节的生物力学行为与膝关节不同，因此仅矫正远端胫距关节角可能无法在整个踝关节实现生理性负荷传递。对于患有关节炎的内翻踝关节进行骨平衡，可能不仅需要矫正额状面的关节面角度，还可能包括双平面矫正以改善距骨覆盖情况，以及腓骨截骨术以恢复踝关节的一致性。
