Modified Watson-Jones technique for chronic lateral ankle instability in athletes: clinical and radiological mid- to long-term follow-up.

摘要

BACKGROUND: We clinically and radiologically assessed mid- to long-term follow-up of a group of patients treated with a modified Watson-Jones technique for chronic ankle instability. METHODS: Fourteen athletes were retrospectively evaluated with physical examination, and Tegner, Good and AOFAS scales; moreover, a 2-view stress, side-to-side X-ray, was performed. RESULTS: All patients were followed-up at a mean of 10.8 years. No one reported further ankle sprains. Mean Good scale value decreased from 3.7 to 1.6, while the Tegner scale decreased from 6.8 to 5.1; the mean AOFAS score was 92.2. Mean sagittal-plane ROM was 62.3 degrees (4.9 degrees S/S difference), while mean coronal-plane ROM was 25.5 degrees (3.8 degrees S/S difference). Mean X-ray talar tilt angle was 4.5 degrees (0.1 degrees S/S difference), while mean anterior drawer test angle was 5.4 mm (0.5 mm S/S difference). CONCLUSIONS: The modified Watson-Jones procedure seems to be a reliable technique in providing satisfactory mid- to long-term clinical and radiological results.
