The aim of this article is to explore the clinical efficacy of distraction arthroplasty in the treatment of moderate\u2010to\u2010severe ankle arthritis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A retrospective analysis was conducted with a total of 34 cases who were diagnosed with moderate\u2010to\u2010severe ankle arthritis and treated by distraction arthroplasty from January 2007 to November 2021. The average age was 42.3\u2009years. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle\u2013hindfoot score and pain visual analog scale (VAS) were used to evaluate ankle pain and functional improvement before surgery and at the last follow\u2010up. Based on age, the patients were divided into the \u226445\u2010year\u2010old group [young group, 15 cases, age (36.37\u2009\u00b1\u20094.31)\u2009years old] and the &gt;45\u2010year\u2010old group [middle\u2010aged and elderly group, 19 cases, age (53.74\u2009\u00b1\u20093.17)\u2009years old]. The analysis included comparing preoperative and postoperative AOFAS ankle\u2013hindfoot and VAS scores and the influence of age on distraction arthroplasty.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>All 34 patients were followed up, and the follow\u2010up time ranged from 13 to 143\u2009months, with an average of 45.3\u2009months. The follow\u2010up times for the young and middle\u2010to\u2010elderly groups were (33.19\u2009\u00b1\u200921.37)\u2009months and (55.63\u2009\u00b1\u200929.69)\u2009months, respectively. At the last follow\u2010up, the AOFAS ankle\u2013hindfoot and VAS scores were significantly improved compared with the preoperative assessment (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). According to the etiological analysis, except for Pilon fracture, which showed no differences pre\u2010 and postoperation in the AOFAS ankle\u2013hindfoot score and VAS score (<jats:italic>p<\/jats:italic>\u2009&gt;\u20090.05), all other patients showed significant differences in these two scores (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). The difference in preoperative AOFAS ankle\u2013hindfoot scores between the young and middle\u2010to\u2010elderly groups was statistically significant (<jats:italic>t<\/jats:italic>\u2009=\u20093.422, <jats:italic>p<\/jats:italic>\u2009=\u20090.021).
