Category:Ankle ArthritisIntroduction/Purpose:We report our early results of the Infinity Total Ankle Arthroplasty (TAA) system, a third generation, constrained implant, recently introduced to the UK market.Methods:All ankles were uncemented and standard instrumentation was used. Patients were reviewed at 3, 6 and 12 months for radiological and clinical assessment including Ankle Osteoarthritis Score (AOS), Visual Analogue Scale (VAS) and subjective component of AOFAS Ankle/Hindfoot score.Results:Mean age was 66 (range 42-88), 14 females and 21 males. The mean follow-up 12 months (range, 4-18 months), and no patients were lost to follow-up.The diagnosis was post-traumatic in 15 cases, primary osteoarthritis in 15 and inflammatory arthritis in 5 cases. Preoperative coronal alignment deformity was < 10 degrees in 54%, 10-20 degrees in 43% and >20 degrees in 3%. Mean AOS score improved from from 64 to 24, AOFAS score improved from 19/70 to 49/70 and VAS from 7.0 to 2.0. Tibial component subsidence was noted i...
