Introduction
The all-inside arthroscopic repair of the anterior talofibular ligament (ATFL) is a technically challenging and still-recent procedure to treat chronic ankle instability (CAI). Favourable clinical outcomes have been shown from originator centers, but this is one of the first series from a non-originator centre. The purpose of the present study is to present the clinical and functional results of patients with CAI underwent arthroscopic all-inside ATFL repair.
Methods
This is a series of cases of 18 consecutive patients who underwent the all-inside arthroscopic ATFL repair, for CAI, after the failure of conservative treatment performed for six months. The evaluation was made using the American Orthopaedic Foot and Ankle Score (AOFAS), visual analog pain scale (VAS), anterior drawer, and talar tilt tests.
Results
All 18 patients were evaluated for a mean follow-up period of 12 months. There was an improvement in the AOFAS (p < 0.001), with the mean improving from 69.6 points to 98.1, standard deviation (SD) = 11.09, and in the mean VAS score (p < 0.001), from 5.0 to 0.5 points (SD = 0.78). All ankles were stable, as assessed by the anterior drawer test and talar tilt test. The only complication found was neurapraxia of the superficial fibular nerve in one patient (5%). All of the patients classified the treatment as good or excellent and returned to sports activities without limitations.
Conclusion
Treatment of CAI by the all-inside arthroscopic ATFL repair was able to restore ankle stability and showed good clinical results and high satisfaction rates.
