[Reconstruction of the proximal insertion of the anterior cruciate ligament. Studies on the accuracy of a non-instrumental method].

The isometry of the femoral and tibial insertion is of decisive importance for the stability of a prosthetic anterior cruciate ligament. A large number of techniques and instruments have been developed to determine the point of isometric femoral insertion. Experiments with 20 cadaveric knees show that the proximal insertion of the anterior cruciate ligament is accurately reconstructed by means of the surgical procedure briefly presented in this paper; the use of positioners is not necessary.
