Reconstruction of the lateral ligaments of the ankle has been performed for many years, but few reports are available regarding the outcome after 10 years or longer, and there are no such reports on reconstruction with the more recently developed artificial ligaments. I report the clinical outcome and radiological findings.

Materials and results: The subjects are 62 feet in 57 patients (male 28 feet, female 34 feet). All patients were followed up by direct examination and stress roentgenography for 10 years or longer. Mean follow-up period is 11 years and 9 months.

On stress X-ray taken at the final examination, TTA improved preoperatively 19 degrees to 4 degrees postoperatively, and ADT improved from 12 to 5 mm. There was no marked development or progression of arthropathic changes. No allergic reaction to the artificial ligament material occurred in any patient. postoperatively and no patient had instability that became severe enough for reoperation to be required. As for arthropathic changes, in 3 patients with a TTA of 10 degrees or more postoperatively, progression of mild osteoarthritic changes was observed.

Discussion: There have been few studies involving long-term follow-up for 10 years or more. This procedure is not happened OA changes and ADL limitation because reconstruction at anatomical position of ATFL and CFL. It has not been happened pathological rupture of artificial ligament because lateral ligaments are not intra-articular ligament but periarticular ligament.

Conclusion: Reconstruction with artificial ligament is anatomical procedure and can be expected the prolonged effectiveness.
