[Conservative functional treatment of fibular capsule ligament rupture even in the performance athlete?].

In a prospective randomised study we examined 80 men and women of 18 to 45 years of age and 40 competitive sportsmen and sportswomen with fresh ruptures of the talofibular and calcaneofibular ligaments treated either surgically or conservatively by functional bracing. We controlled the results by anamnesis and by clinical and radiological follow-up. Conservative treatment leads to the same results after 3-8 months as surgical treatment (5 +/- 2 degrees of talar angulation). Functional conservative treatment results in earlier painless weight bearing in comparison to the surgical treatment which was, however, combined with three weeks immobilization directly after surgery. This proves the superiority of the early functional conservative treatment as long as there are no bony capsuloligamentous tears, osseocartilaginous lesions of the joint surface with splintered-off chips or "flakes" of cartilage ("flake fractures") or reruptures of a chronically unstable ankle joint. The similarly good results achieved in the group of 40 sportsmen and sportswomen by early functional conservative treatment do not justify operation of ruptures of the talofibular and calcaneofibular ligaments.
