Arthritis Research Canada scientific experts have been at the forefront of hip osteoarthritis (OA) research since the launch of IMPAKT-HiP (Investigations in Mobility, Physical Activity, and Knowledge in Hip Pain) – a $2.5 million project funded by the Canadian Institutes of Health Research.

Our scientists are studying the causes of hip pain, particularly femoroacetabular impingement (FAI), and looking for strategies to slow or prevent the progression of hip OA. One of the goals of the IMPAKT-HiP research is to determine whether people with FAI, compared to those without, are at greater risk of developing hip OA. Additionally, researchers are interested in evaluating whether certain physical activities, alone or in combination with FAI, may lead to the early onset of hip OA. This research is important as it may unlock the potential to identify people at risk for developing hip OA early and before the hip is damaged.
