Date Jan. 6, 1994Ancillary instruments for the reconstruction of a posterior cruciate knee ligament by drilling one or two tibial canals using a surgical operation performed from the front. The instrument set includes a system for protecting the posterior surface of the upper tibia end and an aiming device for guiding at least one drill. The protection system comprises at least one bent tube removably coupled by an extension portion to a locking handle for securing the tube through the intercondylar fossa of the femur on the posterior surface of the upper end of the tibia, so that the distal end of the bent tube serves as the stop to the drill guided by the aiming device and emerging from the tibial bone canal, and the bent tube can form, together with a rectilinear wire feed-through tube disposed in the place of the drill, a continuous canal for guiding a metallic loop used to draw the prosthetic posterior cruciate knee ligament from the anterior surface of the tibia to the femur insertion point.
