ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a retainer for tendons used in the reconstruction of the anterior cruciate ligament of the knee.
The conventional method for reconstructing the anterior cruciate ligament of the knee entails drilling a hole that passes through the tibial and femoral condyles. A frame, provided with slots for the passage of two tendons recovered from the tendinous muscle and from the gracilis muscle, is driven through the tibial inlet of the hole. When the frame has exited from the femoral inlet of the hole, it is orientated diametrically to said hole and the tendons are pulled and anchored to the tibial cortex.
The retainer according to the prior art entails the substantial drawback that it does not allow to correctly tension the bundles of tendons. Tendon tensioning in fact occurs simultaneously with their fixation and can no longer be adjusted once fixation has been completed.
SUMMARY OF THE INVENTION
The technical aim of the present invention is to provide a new retainer which allows to eliminate the above drawbacks.
Within the scope of this aim, an object of the present invention is to provide a retainer which is capable of facilitating the operating technique for its installation.
This aim and this object are achieved by a retainer for tendons used in the reconstruction of the anterior cruciate ligament of the knee, characterized in that it comprises a cylindrical body having a flange at one end and an eyelet at the other end, the tendons being engaged through said eyelet and being guided through a hole formed through the femoral and tibial condyles, said body being insertable until said flange abuts against the femoral inlet of said hole.
