Based on the results of comparable studies, patients of the Kantonsspital Liestal, who had sustained injuries of the lateral capsulo-ligamentous structures of the ankle are treated with early functional therapy. Osseous lesions are excluded prior for treatment. Since 1990 a special ankle brace with laces is used. A standardised questionnaire was developed for follow-up. Subjects of interest were: the patients individual experience regarding treatment method and the patients subjective feelings regarding stability, remaining symptoms and limitations in daily activity. 89 questionnaires were returned. 91% rated the treatment as excellent or good. 15% reported a chronic instability. Only 1 patient underwent secondary reconstruction of the lateral ankle ligaments.
