[Lateral ligament injuries of the ankle joint].

Lateral ligament injuries are the most common sports injury and have a high incidence even in non-sportive activities. Although lateral ligament injuries are very common there is still a controversial debate on the best management. The diagnosis is based on clinical examination and X-ray images help to rule out fractures. Further imaging, especially magnetic resonance imaging (MRI) is used to diagnose associated injuries. According to the recommendations of the various scientific societies the primary therapy of lateral ligament injuries is conservative. Chronic ankle instability develops in 10-20 % of patients and the instability can be a result of sensomotoric deficits or insufficient healing of the lateral ligament complex. If the patient does not respond to an intensive rehabilitation program an operative reconstruction of the lateral ligaments has to be considered. Most of the procedures currently performed are anatomical reconstructions due to better long-term results compared to tenodesis procedures.
