Kinetostatic model of the human knee for preoperative planning: Part B: Clinical application for medical decision making

Abstract

In anterior cruciate ligament (ACL) graft surgeries, the location of the insertion point is a critical definition for the functional success of the surgery and patient health. This location is determined during preoperative planning and can be defined according to some criteria such that the biomechanical function is preserved in its best. In this work, simulations based on the method previously presented in part A are presented, taking experimental data available in the literature. Here, this clinical application uses the in situ force of the ACL at selected insertion points as criteria. This aims to determine the graft insertion points, at femur, that best leads to the natural response of an intact knee. Results show the applicability of the method as a support tool for medical decision making in the preoperative planning period.
