Comparison of clinical efficacy between arthroscopic modified suture and common suture in treatment of chronic ankle instability Jinan university type ⅡA anterior talofibular ligament injuries
Objective To compare the clinical efficacy of arthroscopic modified suture and common suture in the treatment of chronic ankle instability Jinan university type Ⅱ A anterior talofibular ligament injuries.Methods A retrospective analysis of 100 cases(Including 10 cases in Dongsheng Hospital,Zhongshan City,and 90 cases in the First Affiliated Hospital of Jinan Uni-versity)with chronic ankle instability and large Ⅱ A type anterior talofibular ligament injuries and underwent arthroscopic surgi-cal repair treatment from June 2019 to February 2021 in the author's team was conductedon.In accordance with the method of randomized numerical table,the patients were randomly divided into 2 groups,50 cases in the modified suture group and 50 cases in the modified suture group.American Orthopaedic Foot and Ankle Society(AOFAS)score,Visual Analogue Scale(VAS)score,and anterior drawer test were compared between the two groups at the last follow-up.Results All patients were followed up for 24 months.The AOFAS score was(82.2±7.69)in the modified suture group and(78.12±11.79)in the suture group at the last follow-up;the AOFAS score was higher in the modified suture group than in the suture group at the last follow-up,with a statistically significant difference(t=2.050,P=0.043).The VAS score was(1.40±0.49)in the modified suture group at the last follow-up and(1.50±0.58)in the suture group;the difference in VAS score between the two groups at the last follow-up was not statistically significant(t=0.927,P=0.356).Anterior drawer test in the modified suture group at the last follow-up:39 cases of grade 1 and 11 cases of grade 2;in the suture group:38 cases of grade 1 and 12 cases of grade 2;the difference in anterior drawer test between the two groups at the last follow-up was not statistically significant(x2=0.056,P=0.812).Conclusion Both the ar-throscopic modified and common suture methods for treatment of chronic ankle instability with Jinan university type Ⅱ A ante-rior talofibular ligament injuries are safe and effective,and the modified suture method has superior functional efficacy over the common suture method in patients who require more postoperative ankle stability.
