Effect of Ankle Osteotomy and Subtalar Joint Fusion on Inverted Ankle Arthritis Accompanied by Subtalar Arthritis and the Follow-up Analysis of Postoperative Foot and Ankle Functions
Objective:To investigate the effect of ankle osteotomy and subtalar joint fusion on inverted ankle arthritis accompanied by subtalar arthritis and its impacts on postoperative foot and ankle functions.Methods:A random number table method was used to divide 60 patients with inverted ankle arthritis accompanied by subtalar arthritis admitted from January 2017 to January 2022 into control group and observation group,with 30 patients in each group.The control group underwent ankle osteotomy,while the observation group underwent ankle osteotomy combined with subtalar joint fusion.The foot and ankle functions,pain level,clinical efficacy,and incidence of complications of the two groups were compared.Results:After one year of follow-up,the AOFAS score,ankle range of motion(AROM),talar tilt angle(TT),tibial articu-lar surface angle(TAS),tibial lateral surface angle(TLS),and tibiocrural angle(TC)of the observation group were greatly better than those of the control group(P＜0.05);after one year of follow-up,the visual analogue scale(VAS)scores of both groups decreased,and the observation group had greatly lower scores(P＜0.05);the total clinical effective rates were 100.00％(30/30)and 80.00％(24/30)in the observation group and the control group,respectively,with greatly higher clinical efficacy in the observation group(P＜0.05);there was no statistically great difference in the inci-dence of complications between the observation group(13.33％)and the control group(23.33％)(P＞0.05).Conclu-sion:Ankle osteotomy combined with subtalar joint fusion can effectively improve the clinical efficacy and postoperative ankle function of patients with inverted ankle arthritis accompanied by subtalar arthritis.
