Few studies have investigated long-term clinical outcomes of a mobile-bearing total ankle arthroplasty (TAA) system. This study analyzed TAA using the HINTEGRA prosthesis at single, non-developer center.Primary TAAs were performed on 213 ankles in 194 patients, and 151 consecutive [71%] 136 patients with minimum follow-up 10 years after primary included this study. Clinical results assessed visual analog scale (VAS) pain score, American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot Scale Osteoarthritis (AOS) disability subscores, range motion. Prosthesis survivorship, reoperations, risk factors also evaluated.The mean was 135.5 months (range, 120.0 to 204.0 months). All scores motion improved significantly from preoperatively 2 years, 4 6 ≥10 (p < 0.001). A 43 (28.5%) required revision procedures, most common reason being periprosthetic osteolysis (32 [21.2%]). The overall implant survivorship 93.5% Kaplan-Meier survival analysis 11.3 TAA.TAA careful observation appropriate adjunct procedures for treatment end-stage arthritis produced satisfactory results, which maintained resulted survivorship.Prognostic Level IV .
