Effects of enzymatic treatments on the depth-dependent viscoelastic shear properties of articular cartilage.
Osteoarthritis (OA) is a disease that involves the erosion and structural weakening of articular cartilage. OA is characterized by the degradation of collagen and proteoglycans in the extracellular matrix (ECM), particularly at the articular surface by proteinases including matrix metalloproteinases (MMPs) and a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTSs).(1) Degradat...
متن کاملSpatial and depth dependent viscoelastic behavior of articular cartilage
The mechanical response of the soft tissues of the knee is nonlinear, anisotropic, and viscoelastic. Individual tissues may also express nontrivial gradients of material properties throughout their structure, adding to the modeling complexity of the anatomy. Computational models of whole knee biomechanics can be extremely useful in understanding the progression of degenerative diseases and trau...
متن کاملViscoelastic properties of human and bovine articular cartilage: a comparison of frequency-dependent trends
BACKGROUND The purpose of this study was to compare the frequency-dependent viscoelastic properties of human and bovine cartilage. METHODS Full-depth cartilage specimens were extracted from bovine and human femoral heads. Using dynamic mechanical analysis, the viscoelastic properties of eight bovine and six human specimens were measured over the frequency range 1 Hz to 88 Hz. Significant diff...
متن کاملViscoelastic properties of bovine knee joint articular cartilage: dependency on thickness and loading frequency
BACKGROUND The knee is an incongruent joint predisposed to developing osteoarthritis, with certain regions being more at risk of cartilage degeneration even in non-osteoarthrosed joints.At present it is unknown if knee regions prone to cartilage degeneration have similar storage and/or loss stiffness, and frequency-dependent trends, to other knee joint cartilage. The aim of this study was to de...
متن کاملViscoelastic properties of bovine articular cartilage attached to subchondral bone at high frequencies
BACKGROUND Articular cartilage is a viscoelastic material, but its exact behaviour under the full range of physiological loading frequencies is unknown. The objective of this study was to measure the viscoelastic properties of bovine articular cartilage at loading frequencies of up to 92 Hz. METHODS Intact tibial plateau cartilage, attached to subchondral bone, was investigated by dynamic mec...
