Double-bundle posterior cruciate ligament reconstruction using bone-semitendinosns and gracilis tendons under arthroscope / 中国医师进修杂志

ABSTRACT

Objective To evaluate the method and effect of double-bundle posterior cruciate ligament (PCL) reconstruction using bone-semitendinosus and gracilis tendons under arthroscope.Methods The data of 16 patients was reviewed,who had underwent arthroscopic PCL reconstruction using the bone-semitendinosus and gracilis tendons from March 2004 to March 2007.A special technique using trephine was allowed for the cylindrical bone plugs attached to the semitendinosus and gracilis tendons.The femoral double-tunnel and the tibial tunnel were prepared,and the adequate press-fit fixations of tendon grafts were ensured within them.Results All patients were followed up.Before operation,the mean Lysholm score was 57 points (43-65 points).While 12 months later after operation,the mean Lysholm score was 86 points (68-92 points).The excellent and good results were obtained in 87.5%.Conclusions Arthroscopic PCL reconstruction using bone-semitendinosns and gracilis tendons can effectively improve the stability of the knee joint.The key to achieve a good treatment is that precise positions of femoral and tibial tunnels in operation and systematic rehabilitation trainings after operation were performed.
