Nanoindentation differentiates tissue-scale functional properties of native articular cartilage.
Cartilage mechanical properties are typically tested at the macroscale. To demonstrate the ability of nanoindentation to characterize in situ articular cartilage properties at the tissue scale, we investigated the local structure-property relationships of intact articular cartilage of a normal rabbit metacarpophalangeal joint. We calculated the mechanical parameters of stiffness, S, resistance ...
متن کاملImaging the Biomechanical Properties of Articular Cartilage
Function: The primary function of articular cartilage is mechanical: under load it must deform to distribute the load over a larger area so as to minimize stress in the underlying bone. In addition, articular cartilage must provide a very low friction surface for gliding when the joint is flexed so that articulating joints move freely. Lastly, it must carry out these two functions for a lifetim...
متن کاملEffect of age on thickness of adult patellar articular cartilage.
The thickness of left patellar articular cartilages after formalin fixation was studied in a series of autopsies on 82 subjects aged 25-96 years. For each specimen the minimal uncalcified cartilage thickness in a transverse patellar slab was determined separately for a 'lateral' segment and a 'central and medial' segment. In the women the cartilage from subjects more than 50 years old showed pr...
متن کاملTetrapolar measurement of electrical conductivity and thickness of articular cartilage.
A tetrapolar method to measure electrical conductivity of cartilage and bone, and to estimate the thickness of articular cartilage attached to bone, was developed. We determined the electrical conductivity of humeral head bovine articular cartilage and subchondral bone from a 1- to 2-year-old steer to be 1.14+/-0.11 S/m (mean+/-sd, n =11) and 0.306+/-0.034 S/m, (mean+/-sd, n =3), respectively. ...
متن کاملDirect Visualisation of the Depth-Dependent Mechanical Properties of Full-Thickness Articular Cartilage.
OBJECTIVE The structural anisotropy of articular cartilage controls its deformation response. As proteoglycans and collagen vary with depth, simple uniaxial compression results in inhomogeneous deformation with distinct depth-dependent mechanical properties. Investigations into depth-dependent mechanical properties of articular cartilage have previously required tissue modification after specim...
