[Bone-patellar tendon-bone ligamentoplasty for the substitution of the posterior cruciate ligament].

The authors describe a technique in which a free patellar tendon graft is used for intraarticular reconstruction of the posterior cruciate ligament through an anterior and posterior approach. Only patients under 50 years of age with functional instability not responding to exercise therapy were elected for this type of surgery. Between November 1982 and May 1988, 12 patients were operated upon. In 9 patients the follow-up averaged 34 months. The subjective results were evaluated following the Lysholm rating system; the objective results were assessed by means of a clinical examination which was always performed by the same physician. The results were very encouraging and warrant a continued use of the technique with proper indications.
