Abstract:
The endoscopic single-incision technique using interference fit screws to secure patellar tendon-bone plugs in the femoral and tibial tunnels has been very popular method for ACL reconstruction. However, several potential complications has been reported such as violation of the posterior wall of the femoal tunnel, laceration of graft during femoral screw insertion, protrusion of the tibial bone block distally due to a lengthy graft and more frequently divergence of the femoral interference screw. We performed 56 consecutive endoscopic ACL reconstruction. In Groi.p I, femoral tunnel drilling were performed at 70-80 degrees of knee flexion. In Group 11, they were done at $5 degrees of knee flexion. Postoperative radiographic analysis of bone-interference screw divergence angle shows 5.9 degrees in AP view, 6.21 degrees in Lateral view in Group I and 3.14 degrees, 3.35 degre.s in Group II respectevely. In conclusion, Bone-interference screw divergence can be decreased with less knee flexion about 45 degree during preparing femoral tunnel.
