title: Surgical reconstruction for chronic lateral instability of the ankle.
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.
