Abstract

We have treated 56 patients (56 ankles) for symptomatic chronic lateral ankle instability by the surgical reconstruction procedure. The operation included lateral shift of the entire lateral capsule–ligament complex, suture to anterior border of fibula, and reinforcement by an elevated periosteal flap of distal fibula.

These patients were reviewed at a mean period of 3.1 years (range, 9 months to 5 years) after the operation. There were 29 males and 27 females with an average age of 29 years (range, 16–49 years).

The clinical results were graded according to the AOFAS Ankle-Hindfoot scales. There were 35 patients who were excellent (above 90 points), 16 who were good (between 76 and 90 points), 4 who were fair (between 60 and 75 points), and 1 who was poor (below 60 points). The excellent and good results amounted to 91.1% (51/56). Therefore, we concluded that symptomatic chronic lateral ankle instability could be successfully managed with this easy and effective surgical reconstruction method.
