Abstract:
Objective:To investigate the efficacy of arthroscopic ligament augmentation repair in the treatment of chronic lateral ankle instability.Methods:The clinical data of 65 patients with chronic lateral ankle instability who received treatment at Shangluo Central Hospital from October 2019 to October 2022 were retrospectively analyzed. The clinical data were divided into three groups based on treatment methods: the mini-open group ( n = 15), in which patients underwent arthroscopy-assisted small incision lateral ligament repair; the arthroscopy group ( n = 15), in which patients received total ankle arthroscopic ligament augmentation repair; and the non-surgical group ( n = 35), in which patients were treated conservatively. The American Orthopedic Foot and Ankle Score (AOFAS) value, the Tegner Activity Scale (TAS) score, Visual Analog Scale (VAS) score, the time to achieve full weight-bearing, and the time to return to sports were compared among all groups. Results:After treatment, AOFAS value and the TAS score increased in all three groups compared with pre-treatment levels, while the VAS value decreased in all groups. All differences were statistically significant ( t = 6.53, 7.45, 6.58, 6.50, 7.62, 6.52, 6.80, 7.50, 6.49, all P < 0.01). There were no significant differences in AOFAS value, TAS score, and VAS score among the three groups (all P > 0.05). The time to achieve full weight-bearing in the arthroscopy group was 6.6 (5.5, 9.0) weeks, which was shorter than the 7.4 (6.0, 9.0) weeks in the mini-open group and the 9.4 (7.6, 12.0) weeks in the non-surgical group. These differences were statistically significant ( H = 7.98, P = 0.001). The proportion of patients returning to sports in the arthroscopy group was 80% (12/15), which was higher than the 66% (10/15) in the mini-open group and the 28% (10/35) in the non-surgical group. These differences were statistically significant ( χ2 = 30.78, P = 0.025). The time to return to sports in the arthroscopy group was 12.1 (9.5, 15.0) weeks, which was shorter than the 14.6 (12.0, 18.2) weeks in the mini-open group and the 16.1 (13.2, 19.0) weeks in the non-surgical group. These differences were statistically significant ( H = 8.90, P = 0.001). Conclusions:Ankle arthroscopic ligament augmentation repair for the treatment of chronic lateral ankle instability is safe and shows better clinical efficacy, making it a viable option for clinical practice.
