...Conrad Smith; M. L. Hull; S. M. Howell There are many causes of lengthening of an anterior cruciate ligament soft-tissue graft construct (i.e., graft + fixation devices + bone ), which can lead to an increase in anterior laxity. These causes can be due to plastic deformation and∕or an increase...

..., defined as the ratio of the pull-out force to insertion force, and the critical insertion depth, which causes the onset of plastic deformation, are analyzed. It is shown that the insertion force is a function of the taper angle, the contact length, the inner and outer radii of the implant, the static...
