TLDR
Results indicate that (a) a smooth transition occurs in the stress-strain and modulus-strains responses between the tensile and compressive regimes, and (b) cartilage exhibits orthotropic symmetry within the framework of tension-compression nonlinearity.About:

The role of interstitial fluid pressurization in articular cartilage lubrication
TL;DR: In this paper, the role of interstitial fluid pressurization on cartilage lubrication has been investigated and a theoretical framework that embodies this relationship has been validated against experiments, predicting and explaining various outcomes, and demonstrating that a low friction coefficient can be maintained for prolonged loading durations.

Validation of finite element predictions of cartilage contact pressure in the human hip joint.
TL;DR: A three-dimensional finite element model for predicting cartilage contact stresses in the human hip using subject-specific geometry from computed tomography image data was developed and validated to assess the sensitivity of model predictions to boundary conditions, cartilage geometry, and cartilage material properties.

Modeling the Matrix of Articular Cartilage Using a Continuous Fiber Angular Distribution Predicts Many Observed Phenomena
TL;DR: The main picture emerging from this analysis is that the anisotropy of the fibrillar matrix of articular cartilage is intimately dependent on the mechanism of tensed fiber recruitment, in the manner suggested by the recent theoretical study.
Journal ArticleDOI
On the theory of reactive mixtures for modeling biological growth.
TL;DR: It is shown that explicit mechanisms of growth-induced residual stresses can be predicted in this framework, and Simplifications appropriate for biological tissues are also proposed, which help reduce the governing equations into a more practical format.
Journal ArticleDOI
Depth-dependent compressive equilibrium properties of articular cartilage explained by its composition
TL;DR: The main insight from this study is that the depth-dependent material behavior of articular cartilage can be obtained from its depth- dependent composition only, which eliminates the need for the assumption that the material properties of the different constituents themselves vary with depth.

A direct spectrophotometric microassay for sulfated glycosaminoglycans in cartilage cultures.
TL;DR: A rapid spectrophotometric procedure is described for the estimation of sulfated glycosaminoglycans in cartilage cultures that is substantially free from interference, is sensitive to less than 1 microgram (4 micrograms/ml) of chondroitin sulfate, and provides a simple alternative to the traditional methods for gly cosaminoglycan determinations.

TL;DR: The visual or histological appearance of a cartilage specimen may be a poor indicator of its ability to function as the bearing material in the intact joint and a more reliable indicator of the functional properties of a specimen can be obtained by direct mechanical testing or by biochemical analysis of its composition.
