Abstract
The great unknown in the joint-replacement problem is how will the bone respond in terms of remodelling to new stress-strain field in bone after the replacement. We studied bone remodelling using our biomechanical model that is in keeping with the facts that the driving force of the remodelling process is the dynamic loading but also with the substantial influence of the biochemical control - osteoprotegerin concentration.
Clinical observations shows that in the course of time the denser regions in the bone shift in the distal direction towards the implant tip. This type of results is also obtained using our model.
