[Combination auto-heteroplasty in ligament repair in chronic anterior laxity of the knee].

From September 85 to September 88, 130 patients were treated by our own technique for chronic laxity of the knee. All the patients were examined at regular intervals (6, 12 and 24 months) both clinically and by arthroscopy. Neuromorphological studies, an experimental approach with the "Pivot" and evaluation of the results, show that surgery is indicated, especially in young patients, before intraarticular lesions appear.
