The dependence of knee joint stability on the cruciate and collateral ligaments

Abstract

In this review, the methods and outcomes of cadaveric experiments that have measured anterior-posterior translation, internal-external rotation, and varus-valgus rotation at discrete flexion angles are summarized. The contribution of the cruciate and collateral ligaments to joint stability was quantified by comparing changes in kinematics as a result of ligament resection. The prevailing trend in the literature indicates that ligaments are maximally engaged towards extension, and that passive joint motion increases through the flexion arc. When ligaments are compromised due to injury or pathology, an understanding of the passive path of motion is essential to effective treatment. We have hig..
