Cam Type FAI is a Cause of Hip Pain in the Young Adult and a Precursor to OA

"Low dose computed tomography, also known as qCT, is sensitive to the mineral content within bone tissue, and can assess bone mineral density, a strong predictor of bone strength and stiffness, which can influence the health of the cartilage. Participants will undergo a low dose CT scan of both hips.~Participants in the Cam Group will undergo this scan once as part of their standard of care. Participants in the Control Group will undergo this scan once as part of the study."

"Collection of blood and urine allows the researchers to look for a biomarker in the blood and urine that might help to predict the evolution of disease/hip osteoarthritis. Identifying a marker in the blood and urine that could be used for early detection of individuals with cam deformity that are at-risk of hip degeneration could greatly improve patient care.~Participants in the Cam Group will undergo the blood and urine collection twice; once before surgery and once 2-years post-operative. Participants in the Control Group will undergo a blood and urine collection once as part of the study."

"The purpose of the questionnaires is to assess how much trouble the participant is having with their hip and how it affects their quality of life.~Participants in the Cam Group will complete the questionnaires twice; once before surgery and once 2-years post-operative. Participants in the Control Group will complete the questionnaires once as part of the study."

"The EOS® uses a new imaging technique that allows precise measurement of the hip and pelvis geometry and structure. This innovative x-ray technique exposes participants to 2-10 times less radiation than a routine x-ray and can capture multiple images at once.~Participants in the Cam Group will undergo the EOS scan twice; once before surgery and once 2-years post-operative. Participants in the Control Group will undergo the scan once as part of the study."

"Positron emission tomography combined with magnetic resonance imaging (PET-MRI) is a technology that allows physicians to examine bone and cartilage at the molecular level.~Participants in the Cam Group will undergo the scan twice; once before surgery and once 2-years post-operative. Participants in the Control Group will undergo the scan once as part of the study."

"Motion analysis is the study of how joints move and which muscles fire during specific movements. In the lab, participants will be asked to perform movements that they might do during a typical day or when exercising.~Participants in the Cam Group will undergo the Motion Analysis session twice; once before surgery and once 2-years post-operative. Participants in the Control Group will undergo the Motion Analysis session once as part of the study."

"Participants will undergo a 3-Tesla (3T) Magnetic Resonance Imaging (MRI) of both hips.~Participants in the Cam Group will undergo this scan once as part of their standard of care. Participants in the Control Group will undergo this scan once as part of the study."
