Articular cartilage is an avascular connective soft tissue in the diarthrodial joints and functions in a highly demanding mechanical environment. The degeneration or wear of the cartilage is a huge problem that effects millions of people every year.

The long term objective of the present work is to develop an analytical articular cartilage growth model. A simplified 2D axisymmetric representation of the human knee joint, including cartilage layers, meniscus and underlying bones, was developed. The cartilage was modeled as a biphasic fluid saturated porous medium and an uniform growth was simulated by a thermal expansion of the solid phase.

The results obtained in the current work show that the cartilage was seen growing onto the implant with time. The deeper the implant, the higher the cartilage grew onto the implant, and into the gap between the cartilages. This and other results will be presented.
