Abstract:
[Objective]To explore the "acute angle" of femur,and evaluate the bone tunnel technique in posterior cruciate ligament reconstruction.[Method]Using the porcine flexor digitorum tendon as graft,the author reconstructed posterior cruciate ligament.The bone tunnel was established with the angle of 80?,90?and 100?comparison the tunnel and intercondylar fossa of femur side wall,and press sensitive film was set between the edge of tunnel and graft.The pressure between was used to represent abrasion.The bigger the pressure was,the larger the abrasion was.The difference of pressure between bone tunnel technique group and the control group was compared.[Result]The pressure of angle 100?was lowest(3.55?0.21 MPa).And the pressure of burnishing group(3.29?0.19 MPa)was lower than that of the control group(3.55?0.21 MPa).[Conclusion]The bone tunnel technique can reduce the femoral;"acute angle" of femur in posterior cruciate ligament reconstruction.
