Collagen of articular cartilage
The extracellular framework and two-thirds of the dry mass of adult articular cartilage are polymeric collagen. Type II collagen is the principal molecular component in mammals, but collagens III, VI, IX, X, XI, XII and XIV all contribute to the mature matrix. In developing cartilage, the core fibrillar network is a cross-linked copolymer of collagens II, IX and XI. The functions of collagens I...
متن کاملCartilage Regeneration – Shaping – Collagen Effects
Abstract Objective: To study the effect of an 830-nm gallium-aluminum-arsenic (GaAlAs) diode laser at two different energy densities (5 and 15 J/cm(2)) on the epiphyseal cartilage of rats by evaluating bone length and the number of chondrocytes and thickness of each zone of the epiphyseal cartilage. Background Data: Few studies have been conducted on the effects of low-level laser therapy on th...
متن کاملSupramolecular Organization of Collagen Fibrils in Healthy and Osteoarthritic Human Knee and Hip Joint Cartilage
Cartilage matrix is a composite of discrete, but interacting suprastructures, i.e. cartilage fibers with microfibrillar or network-like aggregates and penetrating extrafibrillar proteoglycan matrix. The biomechanical function of the proteoglycan matrix and the collagen fibers are to absorb compressive and tensional loads, respectively. Here, we are focusing on the suprastructural organization o...
متن کاملMechanics of Collagen Fiber Network and Fluid Pressurization in Articular Cartilage of Knee Joint
Introduction The load response of a knee joint is dominated by the mechanical properties of articular cartilage, which consists of proteoglycan matrix, collagen fiber network and a fluid. The interplay of these three constituents determines the load support of articular cartilage in the joint. Finite element analysis has been widely applied to study joint mechanics. Accurate knee contact geomet...
متن کاملJoint cartilage repair with transplantation of embryonic chondrocytes embedded in collagen-fibrin matrices.
OBJECTIVE The objective of this study was to assess the feasibility of transplanting embryonic chondrogenic cells within a collagen-fibrin substrate for the reconstitution of full-thickness cartilage defects in chicken knee joints. METHODS Full-thickness cartilage defects were created mechanically on the weight-bearing surface of the tibial condyle in 45 adult chickens and subsequently filled...
