“…A number of studies have been carried out to elucidate the value of operative versus conservative treatment of ruptures of the lateral ligaments o f the ankle (Brostrom 1966, Freeman 1965, Hansen et al 1979, Kolind-S~rensen 1975, Prins 1978, but only a few of these studies have been prospective and controlled.
