Percutaneous Calcaneal Osteotomy Combined With Arthroscopic Lateral Ankle Ligament Reconstruction for Chronic Ankle...

Chronic ankle instability is the most frequent complication of lateral ankle sprain. Its reported incidence is approximately 40% after the first episode of instability. Although this rate varies depending on the type of activity, there are also certain risk factors associated with this condition, such as hyperlaxity, static or dynamic postural control deficits, and especially, hindfoot varus. If hindfoot varus is not managed when medical treatment fails and surgery is necessary, treatment may be unsuccessful, resulting in a poorer functional outcome and a higher rate of recurrent instability. Open hindfoot varus correction is often associated with poor wound healing and infectious complications. If ligament repair is also performed, the risk is increased by the numerous incisions. This article presents an arthroscopic lateral ankle ligament anatomic reconstruction technique with the gracilis tendon associated with percutaneous calcaneal osteotomy for the treatment of chronic ankle instability.
