Factors influencing ankle alignment changes following medial unicompartmental knee arthroplasty: Preoperative knee and ankle deformities and extent of knee alignment correction
Fig 5
Ankle alignment changes following MUKA and its association with preoperative ankle deformities.
While preoperative varus ankle deformity is significantly corrected postoperatively, there is limited improvement in cases of preoperative valgus ankle deformity. (a) Patients with preoperative varus ankle deformity exhibited a correction in HKA angle from 13.4° to 4.1°, and (b) a reduction in PTA angle from 3.4° to 1.6°. (c) Patients with preoperative valgus ankle deformity showed a correction in HKA angle from 13.1° to 4.7°, while (d) the PTA angle changed from -2.8° to -3.4°.
