Abstract
We measured on the radiographs of 100 knees the length of the patellar ligament and the anterior cruciate ligament, and the distance between the tibial tubercle and the femoral insertion of the anterior cruciate. The length of the patellar ligament was always greater than that of the anterior cruciate ligament, but shorter than the distance between the tibial tubercle and the femoral insertion of the anterior cruciate by a mean of 14.2 mm (3 to 22). We conclude that anatomical, isometric replacement of the anterior cruciate is possible using a free graft, but not by the technique of retaining the tibial attachment originally described by Jones (1970).
