title: Biomechanics of the knee joint: a critical review.
abstract: The literature concerning kinematic and kinetic studies on the knee joint is comprehensively reviewed in this article. Also reviewed are studies of etiology and operative treatment of injury, as well as chronic disease such as dislocation, arthritis, and ligamentous rupture. This paper formulates experimental study and mathematical model analysis of the tibio-femoral and patello-femoral joints, respectively. The sections on experimental study cover the following: the tibio-femoral joint including load bearing capacity, knee laxity, ligamentous strain, articular geometry, and multiaxial movement; the patello-femoral joint including forces and stresses and patellar tracking patterns. Further, three items, considered as future problems, are discussed briefly: individual variations in material properties of the soft tissue and biphasic cartilage-bone structures, quantitative description of bone geometry, and quantitative determination of extreme tensions and distortions in connective tissues surrounding the knee.
