Abstract:
Purpose To analyze the gait of patients following reconstruction of posterior cruciate ligament(PCL) and posterolateral corner(PLC).Methods Between March 2007 and April 2008,16 patients with combined PCL and PLC injuries-deficient knee underwent the reconstruction with allograft.Dial test were performed before surgery,and gait analysis and dial test were assessed 1 year after reconstruction.Sixteen healthy volunteers were used as controls.Results There are no differences in the time-distance factors and kinematics between patients and controls(P>0.05).The torque of knee extension revealed significant difference between patients and controls(P<0.01).Mean abtorsion angle of the patients increased 16.5°±6.2° before surgery;whereas the angle increased-4.4°±7.8° 1 year after surgery(P<0.01).The maximal mean abtorsion angnlation from gait analysis was 14.1°±15.7° and from dial test was 29.7°±1 5.2°,respectively.There was a strong linear correlation(r=0.9671,P<0.05)between the outcomes from dial test and gait analysis.Conclusion After reconstruction of the PCL and PLC,the gait of patients became almost normal 1 year after operation,except the torque of knee extension.
