Abstract

Purpose

To compare the short-term outcomes of surgical management of failed ankle arthroplasty with revision ankle arthroplasty and conversion to arthrodesis.

Methods

Single-centre retrospective review of revision procedures for failed ankle arthroplasty between January 2012 and June 2019. Implant survival, union rates, and PROMS data—Pain Visual Analogue Score (VAS), Ankle Osteoarthritis Score (AOS) and Manchester-Oxford Foot Questionnaire (MOxFQ)—were compared between the two groups.

Results

Twenty-nine patients (31 ankles) underwent surgical management for failed ankle arthroplasty, with either revision arthroplasty (n = 21) or arthrodesis (n = 10). Revision arthroplasty had 87% survival at four years. Arthrodesis had an overall union rate of 80%. Two-year PROMS showed greater results for the revision arthroplasty group compared with that for arthrodesis group (Pain VAS 10 vs 50, p = 0.03; total AOS 12 vs 87, p = 0.04; average MOxFQ 17 vs 73.5, p 0.02).

Conclusion

Revision arthroplasty demonstrates good short-term survival data with improvements in PROMS compared with arthrodesis. Further long-term follow-up is required to monitor if these benefits continue.
