SOME IDEAS OF THE LIGAMENT CONFIGURATIONS' EFFECT ON STRAIN CONCENTRATIONS

Abstract

A photoelastic coating method was applied for ligament surface strain measurement on the flat-shape MCL and the irregular-shape ACL. Strain measurement for the MCL using VDA system found that the strain values were higher on both the tibial and femoral insertions than on the midsubstance. In the ACL however, higher strains were observed only on the femoral insertion, but not on the tibial insertion. Similar results were found form our photoelastic measurements subject to the coronal models of MCL and ACL, as well as the actual MCL and ACL. Therefore the strain along the fiber line may vary according to the morphologies of the ligaments.
