Lateral ankle stabilization using bovine collagen material: xenograft bioprosthesis, model GR.

This is a combined research study including use of a reproducible technique for ankle stress x-ray examinations (both preoperatively and postoperatively) and the use of the bovine bioprosthesis tendon implant for stabilization and augmentation of the lateral ankle ligaments. The surgical technique is fully described and the follow-up results indicate that there is long-term ankle stability, and that patient acceptance is very high.
