Cell regulation of periprosthetic bone loss

Funded Activity Summary

Artificial joint implants are widely used to replace diseased or damaged joints. Despite the impressive success of joint replacement many artificial joints do not last indefinitely. In many patients joints last for 25 years or more but in about 15% the artificial joints will fail prematurely. Artificial joints need to be replaced because of loosening resulting from the loss of bone from around the artificial joint. The bone loss is caused by large numbers of small particles generated by excessive wear of the artificial joint. We now know that specialised cells in the body react to the wear particles and try to destroy them. During this process they produce molecules which lead to bone destruction. This project seeks to investigate the way particles cause bone loss and to develop drug treatments that will either prevent the loss of bone or promote new bone to replace that which has been lost. The increasing use of joint replacement and an aging population means that the number of patients with artificial joint failure will increase. This will mean that an increasing amount of medical recourses will be needed to replace failed and painful artificial joints. It is planned that the findings obtained from this project will eventually result in drug treatments which can reduce the need for the replacement of artificial joints.
