Anterior cruciate ligament deficiency after TKA causes femoral forward motion during knee flexion, the so-called paradoxical motion. Stability of the joint is governed by a combination of static ligaments, dynamic muscular forces, meniscocapsular aponeurosis, bony topography, and joint load. The movements that are allowed are determined by the structural classification for each joint.

In closed K chain it works with hip & ankle joints to support body wt. Knee joint (Articulatio genu) The knee joint is a synovial joint that connects three bones; the femur, tibia and patella.It is a complex hinge joint composed of two articulations; the tibiofemoral joint and patellofemoral joint.The tibiofemoral joint is an articulation between the tibia and the femur, while the patellofemoral joint is an articulation between the patella and the … Ligaments like the anterior cruciate ligament essentially control its equilibrium and motion. More recent studies have shown a significant difference between the knee kinematics of the medial and lateral compartment [ 3] (Fig. Sreeraj S R INTRODUCTION FUNCTIONS OF KNEE ARE: 1.

Because of these vital roles, an attempt should be made to save viable meniscus when performing knee … 2. Biomechanics. The menisci are of clinical importance to knee biomechanics as they function to maintain knee joint stability and congruity, resist capsular and synovial impingement during knee motion, support the screw home mechanism, and distribute load over a large area of the articular surface. Knee biomechanics. For example, a multiaxial ball-and-socket joint has much more mobility than a uniaxial hinge joint. It includes many important structures, specific to the knee such as the menisci and cruciate ligaments. March 8, 2017. Anatomy and Biomechanics of the Natural Knee and After TKR.
