Abstract:

Objective　To explore the effect of arthroscopic absorbable knotless suture tape reconstruction for patients with chronic lateral ankle instability caused by anterior talofibular ligament injury. Methods　A total of 110 patients with chronic lateral ankle instability caused by anterior talofibular ligament injury treated in Liaocheng Third People's Hospital from January 2020 to January 2023 were selected for the randomized controlled trial, and were divided into a control group and an observation group by the random number table method, with 55 cases in each group. There were 30 males and 25 females in the control group; they were (55.48±3.57) years old. There were 35 males and 20 females in the observation group; they were (56.38±2.64) years old. The control group took traditional ligament repair surgery, and the observation group arthroscopic absorbable knotless suture tape reconstruction surgery. The American Orthopaedic Foot & Ankle Society Scores (AOFAS), Kofoed ankle function scores, and scores of Y balance test (YBT) and Perceived Ankle Instability (PAI) before and 2 months after the surgery, as well as the incidences of complications and pain scores of Visual Analogue Scale (VAS), were compared between the two groups. t and χ² tests were applied. Results　Two months after the surgery, the scores of AOFAS and Kofoed ankle function in the observation group were higher than those in the control group [(90.13±2.89) vs. (79.27±3.28) and (90.29±2.21) vs. (78.44±2.46)], with statistical differences (t=18.424 and 26.575; both P<0.05); the scores of YBT and PAI in the observation group were better than those in the control group [(88.28±2.69) vs. (78.22±1.66) and (3.02±1.22) vs. (5.34±2.30)], with statistical differences (t=23.603 and 6.609; both P<0.05). The scores of VAS 1 and 2 months after the surgery in the observation group were lower than those in the control group [(3.20±1.15) vs. (6.89±1.26) and (1.34±0.54) vs. (4.64±1.12)], with statistical differences (t=16.041 and 19.683; both P<0.05). The incidence of complications in the observation group was lower than that in the control group [16.36% (9/55) vs. 49.09% (27/55)], with a statistical difference (χ²=13.378, P<0.05). Conclusion　Arthroscopic absorbable knotless suture tape reconstruction in the treatment of patients with chronic lateral ankle instability caused by anterior talofibular ligament injury can significantly improve their ankle function and perceived ankle stability and reduce postoperative pain and complications, so it has high clinical application value.
