Outcomes of Total Ankle Arthroplasty in Moderate and Severe Valgus Deformity.

Published online

Journal Article

INTRODUCTION: Failure to correct coronal deformity at the time of total ankle arthroplasty (TAA) can lead to early implant failure. We aimed to determine clinical, radiographic, and patient-reported outcomes of patients with moderate to severe valgus deformity who underwent TAA for end-stage ankle arthritis. METHODS: Patients with a valgus deformity of at least 10° who underwent TAA were retrospectively reviewed. The coronal tibiotalar angle was assessed on radiographs preoperatively, at 1 year, and at final follow-up. The visual analog scale (VAS) for pain, Short Form-36 (SF-36), American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot-ankle scale, and Short Musculoskeletal Function Assessment (SMFA) scores were assessed preoperatively and at final follow-up. RESULTS: Mean preoperative valgus deformity was 15.5 ± 5.0°, and was corrected to a mean of 1.2 ± 2.6° of valgus postoperatively. VAS, SF-36, AOFAS, and SMFA scores improved significantly ( P < .001 for all). There was no significant change in tibiotalar angle between 1 year and final follow-up in either group. Reoperation and revision rates did not differ between groups. CONCLUSION: Correction of coronal alignment was achieved and maintained in patients with both moderate and severe preoperative valgus malalignment. Outcome scores significantly improved for all patients. LEVELS OF EVIDENCE: Therapeutic, Level IV.
