Abstract:
Objective To provide data on the incidence,shape,and sizes of the femoral attach.ments of meniseofemoral ligaments (MFLs),and to determine the function of MFIJs and the role in the femoral tunnel D0sitioning in the double-bundle reconstruction of PCL.Methods Anatomical study:Thirty cadaveric knees were used to investigate the incidence and tightening-slackening patterns during the knee nexion-extension of MFLs.Data were obtained to describe the size,shape,and the relationship between the position of the femoral attachment of MFLs and that of anterolateral bundle(ALB)and the posteromedial bundle(PMB) were detetrained.Clinical study:During arthroscopic reconstruction of PCL,the presence of MFIJs Was confirmed in 1 12 patients by observation and probing,the relationship between the femoral attachment of MFLs and that of ALB and PMB were determined.Results Anatomical study:The Humphry ligament and Wrisberg ligament were presented in l(3%)and 27(90%)case respectively.The femoral attachments were approximately ellipse both.The mean area was(18.14±3.05)mm2 and(25.63±7.92)mm2 respectively.Clinical study:The Humphry ligament and Wrisberg ligament were present in 2 cases(1.7%)and 67 cases(59.8%) respectively.The incidence of MFLs in knees with isolated PCL injury was highter than that in knees with multiple ligaments injuries.Conclusion The incident of MFLs is related to the trauma of the knee.and the Wrisberg ligament plays an important role in avoiding impingement between the ALB and the intereondylar roof during deep knee flexion.The Humphry ligament and the Wrisberg ligament are landmarks for the tunnel positioning of ALB and PMB in double-bundle PCL reconstruction respectively.
