 3. Correlate this with lubrication and wear properties of the fluid The long term goal is to develop time saving, cost effective, non-invasive diagnostic tests to improve management of a swollen joint. The biomedical research centre at Imperial provides a unique and unparalleled clinical and scientific environment to conduct this research. The Imperial College division of Computational and Systems Medicine has an international reputation in metabonomics and this, together with the high volume of patients with swollen joints treated at Imperial National Health Service Trust c1000yr ensures that the study can take place in an environment conductive to success.
