Abstract:
Objective To investigate a new method for reconstruction of posterior cruciate ligament(PCL)using hamstrings tendons knot and bone lock-bolt under arthroscopy.Methods Ten cases of PCL lesion were treated arthroscopically. Hamstrings were harvested with a stripper following standard procedure. The hamstring tendons tied a knot at the inter-media part of the tendons and insert a bone lock-bolt on the knot. The tunnel of femur and tibia were prepared. Tunnel diameter of the tibia and the infra 1/3 of femur was 5-7mm and the superior 2/3 of the femur side was 11-12mm,Pulling in the tendon from the lateral side of femur tunnel to the tibia.A hole of 4 5mm was drilled 1cm distal of tibia tunnel exit. Create a bone bridge using curved clamps,passing a tendon under the bone bridge and tying the tendon over the bone bridge in extension.Results All the patients were follow-up.Function and stability of knee during walking and activities improved apparently. All patients were evaluated with the knee functional scales.Patients were clinically rated as excellent in 6,good in 3,and fair in 1. There were no poor results.Conclusion The result of using semitendinosus and gracilis tendons tied a knot and implant a bone lock-bolt to reconstruct PCL is satisfactory. The advantages of the technique included well biological match, exemption from costly materials, promotion of healing of tendons and bone tunnel, decrease in medical cost.
