Chronic lateral instability of the ankle. A method of reconstruction using the Achilles tendon.

Reconstruction of the lateral ankle ligaments ad modum Støren, using the medial one third of the Achilles tendon as a nourished transplant is a relatively unknown procedure. Thirty patients operated on using this technique have been evaluated. The mean observation time was 4 years (range 1/2--16 years). All patients but one had a stable ankle joint and were satisfied. One was reoperated after sustaining a new injury 6 months after the original operation. The method described is a good alternative to other methods of ligamentous reconstruction. The procedure also stabilizes the subtalar joint and corrects recurrent subluxation of the peroneal tendons.
