The authors report their experience with ligament repair, using the Kennedy-LAD technique in 19 cases of chronic anteromedial and anterolateral instability. The postoperative follow-up was 3 to 4 years. They conclude that this repair provides excellent stability, but that the results are jeopardized by serious problems of biocompatibility; in 63% there was recurrent synovitis. According to the "Arpège" criteria, there was a mean of 58% poor results and 42% good or excellent results. Twenty-one percent of the patients were satisfied with the operation, and 25% were seriously dissatisfied. Stability, as evaluated by the postoperative radiological active Lachman test, was normal in 84% of the patients (0-6 mm anterior tibial deplacement).
