Cartilage is a tough, semitransparent, elastic, flexible connective tissue consisting of cartilage cells scattered through a glycoprotein material that is strengthened by collagen fibers. There are no nerves or blood vessels in cartilage, which is found in the joints, the rib cage, the ear, the nose, the throat, and between vertebral disks.
Get PriceArticular cartilage is the bearing material that lines the ends of the bones of synovial joints. Its primary function is to reduce friction and wear at the articulations of the musculoskeletal system. The tribological properties of cartilage are intimately related to its structure and mechanical properties.

Get Priceproperties of articular cartilage. Key Words: BIPHASIC THEORY, TRIPHASIC THEORY, FIXED CHARGE DENSITY, INDENTATION, CORRESPONDENCE PRINCIPLE A rticular cartilage is a layer of low-friction, load-bearing soft tissue that overlies the articulating bony ends in diarthrodial joints. It provides the joint with essential biomechanical functions, such as wear
Get PriceDifferent methods for enhancing the mechanical properties of engineered cartilage are also discussed, including scaffold design, mechanical stimulation, and chemical stimulation. This article concludes with recommendations for future research aimed at achieving engineered cartilage with mechanical properties matching those found in native cartilage.
Get PriceBy fitting the mathematical biphasic model to the meas- ured displacement, two material properties of the cartilage are determined: the aggregate modulus and permeability. The aggregate modulus is a measure of the stiffness of the tissue at equilibrium when all fluid flow has ceased.
Get PriceThe knowledge of the topographical variations of articular cartilage material properties is important in terms of the way load is transferred to the subchondral bone because of either altered kinematics or changes in material properties, and even to bone that has suffered some microfracture.
Get PriceArticular cartilage has unique material properties that enable the cartilage to perform its physiological functions over a lifetime and under a wide range of loading conditions. Numerous studies have investigated the relationship between cartilage properties and composition/structure.
Get PriceLet’s consider the materials properties that we might require for cartilage regeneration. Here we need to look at materials that will have very specific properties. They need to match with the modulus of the stiffness of cartilage they need to be compatible with living cells, and must have enough mechanical robustness so as we can actually implant the structure into the defect.

Get PriceIn the first part, the composition and structure of articular cartilage is presented. In the second part, theoretical models of the mechanical behavior of cartilage, experimental methods for the determination of cartilage properties, and material properties for normal, pathologic, and repair cartilage are summarized.

Get PriceArtificial cartilage is a synthetic material made of hydrogels or s that aims to mimic the functional properties of natural cartilage in the human body. Tissue engineering principles are used in order to create a non-degradable and biocompatible material that can replace cartilage. While creating a useful synthetic cartilage material, certain challenges need to be overcome.

Get PriceThe creep response and material properties of lateral tibial plateau cartilage were obtained for wild-type mouse knee joints, by the micro-indentation testing and optimization algorithm. The newly developed genetic algorithm was found to be efficient and accurate when used with the finite element simulations for nonlinear optimization to the experimental creep data.

Get PriceArticular cartilage is a specialized connective tissue suited for the distribution of contact loads within diarthordial joints. It is a biphasic material that exhibits anisotropic and nonlinear elastic behavior. The liquid phase, primarily water, makes up 65% to 80% of the cartilage by weight. The solid phase consists of dispersed proteoglycans
Get PricePrior studies suggest that ligament and meniscus tears cause osteoarthritis (OA) when changes in joint kinematics bring underused and underprepared regions of cartilage into contact. This study aims to test the hypothesis that material and tribological properties vary throughout the joint according to the local mechanical environment.
Get Price1989). Cartilage, in contrast, is a viscoelastic material having both fluid and solid characteristics, and therefore displays strain-rate dependent mechanical and material properties. Unmineralized cartilage, such as bovine articular cartilage, becomes stiffer with increasing strain rate (Li et al., 2003; Park et al., 2004).
