Abstract:
Objective:To compare the clinical efficacy of patients with chronic lateral rotational ankle instability(CLRAI) after all-inside arthroscopic lateral ligament augmentation procedure and Brostr?m procedure.Methods:This is a retrospective cohort study. The clinical and imaging data of 106 CLRAI patients were collected at the Xuzhou Central Hospital from January 2021 to December 2022. The patients included 55 males and 51 females with an age of (32.6±8.2) years (range: 16 to 50 years). All patients were treated under all-inside arthroscopic, and were divided into Brostr?m-Gould surgery group ( n=54) and Brostr?m surgery group ( n=52) according to different ligament repair methods. At 3, 6, and 12 months after surgery, ankle inversion stress tests and anterior drawer tests were used to examine the stability of the ankle joint and observe gait. The American Orthopedic Foot and Ankle Society ankle hindfoot scale (AOFAS-AH) and Karlsson ankle function score (KAFS) were used to assess ankle function; Tegner score was used to assess the patient′s level of exercise; the foot and ankle outcome score(FAOS)(including score of symptoms,pain,function, daily living,function, sports and recreational activities (sport); quality of life (QOL) was used to assess the patient′s daily activity ability. Comparisons of data were made using independent sample t test, repeated measures analysis of variance, LSD- t multiple comparison method, χ2 test or Mann-Whitney U test. Results:All operations were successfully accomplished. All incisions healed by first intention, without evidence of postoperative complications of implant rejection, ligation reaction, and nerve and vessel injury. All patients were followed up at 3, 6, and 12 months after surgery. Ankle varus stress test and anterior drawer test were negative. No evidence supporting lateral ankle instability was obtained. All patients eventually regained normal gait. No patients underwent revision surgery. Repeated measurement analysis of variance showed that AOFAS-AH, Tegner, KAFS and FAOS scores in the Brostrom-Gould group and the Brostrom group were significantly higher than those before surgery ( P<0.01). The change trends of Tegner score and FAOS-sport score were significantly different between the two groups ( F=18.839, P<0.01; F=8.169, P=0.005). Multiple comparisons revealed that at 3-, 6-and 12-month follow-up, the Tegner scores (3 months: 3.7±0.5 vs. 3.3±0.5, t=-3.980, P<0.01; 6 months: 4.4±0.6 vs. 3.8±0.7, t=-4.792, P<0.01; 12 months: 5.8±0.9 vs. 5.1±1.0, t=-3.889, P<0.01), sport scores (3 months: 82.5±3.7 vs. 79.3±3.8, LSD- t=-4.316, P<0.01; 6 months: 88.5±4.9 vs. 85.7±3.8, LSD- t=-3.312, P=0.001;12 months: 90.1±4.3 vs. 88.2±5.1, LSD- t=-2.112, P=0.037) in the Brostr?m-Gould surgery group were higher than those in the Brostr?m surgery group, with statistical significances. Conclusions:Both Brostr?m-Gould and Brostr?m procedures under all-inside arthroscopic can make ankle stability and improve ankle function in the treatment of CLRAI. However, the former maybe shorten the time to return to exercise and achieve higher motor function.
