The aim of this operation is to achieve anatomic ACL reconstruction using autologous (patient’s tendon) under arthroscopic control. The principle of TLS is to use a single hamstring tendon in short graft (transplant economy). The half tendon tendon is one of two hamstring tendons (hamstring). It is thin (3-4 mm) and long (about 25 cm). It is the termination of the semitendinosus that ends on the bridle. The harvesting the graft is carried out by a short nearly horizontal incision of 2 cm to the surface of the tibia, is removed only the semitendinosus tendon over its entire length with a stripper. He bent over backwards to get a transplant ACL bundles 4 or 4 strands with diameters ranging from 7 to 9 mm. It’s a short graft50 mm average length (Fig.8). At both ends of the graft are passed two textile strips for fixing the graft in tunnels. a traction table is used to make a claim to the graft to 500 Newtons.
The procedure is performed arthroscopically: two small incisions of 5 mm either side of the ball joint enable switch the camera and instruments to perform the ligament. The preparation of the notch allows the cleaning of the axial face of the lateral condyle and visualize the area well “over the top” in order to delimit the dial 9-12 and 12-15h for a right knee to the left knee. The femoral tunnel is drilled under arthroscopic control inwards with a specific femoral viewfinder. The knee is at 90 ° of flexion. Tunneling on the spindle diameter 4.5 mm is formed using the 4.5 mm drill.
The femoral stall is then excavated using an auger to specific fins. The arthroscope is controlling the retrograde manual digging. The tibial tunnel is achieved according to the same principle. Tractors son went inwards in the femoral and tibial tunnels. The graft is then towed on his bandages and is positioned automatically in the femoral and tibial stall. The graft is fixed with two metal screws Titanium.
