Motion Characteristics

The motion patterns of the human knee joint depend on its passive motion characteristics, which are described by the ligamentous and articular constraints. Since active motions, like walking and squatting are believe to fall within a passive envelope, the basis for the understanding of the knee joint kinematics lies in the description of its passive characteristics.

By generalizing a previous model proposed in the literature, a new spatial kinematic model of the knee joint passive motion is presented. The model is based on an equivalent spatial parallel mechanism which relies upon the assumption that fibers within the anterior cruciate ligament (ACL), the medial collateral ligament (MCL) and the posterior cruciate ligament (PCL) can be considered as isometric during the knee flexion in passive motion (virtually unloaded motion). The articular surfaces of femoral and tibial condyles are modelled as 3-D surfaces of general shapes. In particular, the paper presents the closure equations of the new mechanism both for surfaces represented by means of scalar equations that have the Cartesian coordinates of the points of the surface as variables and for surfaces represented in parametric form. An example of simulation is presented in the case both femoral condyles are modelled as ellipsoidal surfaces and tibial condyles as spherical surfaces. The results of the simulation are compared to those of the previous models and to measurements. The comparison confirms the expectation that a better approximation of the tibiofemoral condyle surfaces leads to a more accurate model of the knee passive motion.

Background: Of the synovial joints in the body knee joint is the largest. Each meniscus is a piece of fibrocartilage with a thickened outside edge and a thin inner edge so that it is wedge-shaped in cross section. The purpose of the present study was to establish database on standard dimensions in knee menisci of adults of north Indian population.Methods: The sample for this study was collected from April, 2012 to June, 2013. For this study, 200 menisci (100 right and left each) of 50 adult humans were taken for analysis. Measurements were done with the help of non-elastic thread and digital vernier calipers. All dissections were performed in a systematic fashion.Results: The width of the lateral meniscus was significantly different form medial meniscus with lateral and medial menisci widest in middle and posterior third respectively. The middle one third of both lateral and middle menisci was the thickest.Conclusions: It is always good to have a set of anatomical morphometric parameters of the menisci like the width and thickness. The measurements of suitable grafts may provide a more acceptable meniscal replacement in the future.

The motion patterns of the human knee joint depend on its passive motion characteristics, which are described by the ligamentious and articular constraints. Since active motions, like walking and squatting are believed to fall within a passive envelope, the basis for the understanding of the knee joint kinematics lies in the description of its passive constraint characteristics [1]. The link between the knee passive envelope and the kinematics during various dynamic activities has not been studied. It is unclear how the articular geometry and muscle activations of the knee influence the contribution of ligament constraints during dynamic activities. To explain the relationship between knee passive envelope and dynamic activities completely, new methodology must be developed. The objective of the present study was to estimate the effects of variation in passive knee envelope on the tibiofemoral kinematics during dynamically simulated gait using a multivariate analysis technique, principal component (PC) analysis.
