The authors describe a new procedure for replacement of both cruciate ligaments. They use a single anterior approach and a unique transplant, consisting of a long band including part of the patellar tendon, part of the patella and part of the quadriceps tendon. The technique is indicated in some cases of major instability of the knee.
