BACKGROUND: Ankle arthrodesis has historically been the standard treatment for end-stage ankle arthritis but may accelerate subtalar joint (STJ) degeneration. Stemmed total ankle replacement (TAR) preserves ankle motion but raises concern for iatrogenic STJ injury from intramedullary instrumentation.
PURPOSE: To evaluate the long-term incidence of subtalar osteoarthritis following stemmed TAR at a minimum 10-year follow-up.
STUDY DESIGN: Retrospective cohort study.
METHODS: A retrospective review identified 70 patients who underwent primary stemmed TAR between January 2012 and December 2013. Sixteen patients met inclusion criteria of ≥10 years follow-up with complete radiographic data. STJ osteoarthritis was graded preoperatively and at final follow-up using the Kellgren-Lawrence Scale (KLS) on weightbearing radiographs. Statistical analysis included Mann-Whitney U and chi-square testing with significance set at p < 0.05.
RESULTS: Mean follow-up was 11.49 ± 0.9 years. Two patients (13%) demonstrated radiographic progression in KLS grade, and no patient required subtalar arthrodesis. Postoperative STJ pain occurred in 6 patients (38%), although 4 demonstrated no radiographic progression. STJ pain was significantly associated with moderate-to-severe implant-related complications requiring reoperation (p = 0.0357) but not with KLS progression (p = 0.0510). Radiographic progression was associated with talar collapse rather than isolated STJ degeneration.
CONCLUSIONS: At long-term follow-up, stemmed TAR demonstrated minimal progression of subtalar osteoarthritis and no cases requiring STJ fusion.
