Impact loading of articular cartilage during transplantation of osteochondral autograft.
Surgical reconstruction of articular surfaces by transplantation of osteochondral autografts has shown considerable promise in the treatment of focal articular lesions. During mosaicplasty, each cylindrical osteochondral graft is centred over the recipient hole and delivered by impacting the articular surface. Impact loading of articular cartilage has been associated with structural damage, los...
متن کاملViscoelastic Behavior of Articular Cartilage under Dynamic Shear and Compressive Loading following Enzymatic Treatment
INTRODUCTION: The viscoelastic behavior of articular cartilage is derived from complex interactions involving the fluid and the extracellular matrix (ECM) of proteoglycans (PG) and collagen fibrils. Enzymatic digestion of the ECM components makes it possible to study specific structure-function relationships of articular cartilage. To some extent, enzymatic treatment also simulates the patholog...
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 کاملIn situ measurement of articular cartilage deformation in intact femoropatellar joints under static loading.
The deformational behavior of articular cartilage has been investigated in confined and unconfined compression experiments and indentation tests, but to date there exist no reliable data on the in situ deformation of the cartilage during static loading. The objective of the current study was to perform a systematic study into cartilage compression of intact human femoro-patellar joints under sh...
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...
