Introduction/Purpose:
Total ankle arthroplasty (TAA) continues to be investigated as a primary treatment for end-stage ankle arthritis. The objective of this study was to report mid- to long-term results of the Salto Talaris TAA using patient reported outcomes and retention rates with mid- to long-term follow up.
Methods:
This was a multicenter retrospective study using prospectively collected data. 316 patients received a Salto Talaris TAA at one of three institutions from 2005-2015 were included in the study. Outcomes included subdomain scores of the SF-36 (bodily pain and physical function) and adverse events including additional surgeries or revision/removal of components.
Results:
Statistically significant improvements were seen in pain and physical function scores at 2 year follow up and were maintained through most recent follow-up. Retention rate of the prosthesis was >95% in all patients (30/32 at > 10 years, 272/284 at 4.5-10 years). 14 patients underwent revision or removal of prosthesis. 15 patients had additional surgery that did not involve revision or removal of components.
Conclusion:
Treatment of end-stage ankle arthritis with the Salto Talaris implant provides patients with improved pain and functional outcome scores in long-term follow up. Low revision rates demonstrate the durability of this prosthesis.
