Femoro-acetabular impingement (FAI) is a known cause of hip pain and possibly a major cause of adult hip osteoarthritis. The relationship between cam-type FAI deformity characteristics and joint degradation to better identify 'at-risk' patients requiring corrective surgery will be scrutinized to gain a better understanding of the condition's natural history. The influence of certain morphologies (e.g. size and location of the deformity) will be analyzed to determine if this leads to aberrant loading of regions of the cartilage and subchondral bone, resulting in cartilage damage and joint degradation. Additionally, this research will determine if changes in the subchondral bone precede cartilage degeneration. The methodology for establishing the morphology/cartilage degeneration relationship includes Magnetic Resonance Image (MRI) analysis, three-dimensional motion analysis and computer simulation/finite element analysis. The outcomes of this research may lead to a reduction in total hip replacement cases by as much as 70%, saving many Canadians from a painful and debilitating condition and reducing costs to the Canadian health care system by as much as $290 million annually.
