Outcomes

Primary Outcome Measures

Assessment of [18F]-NaF as a biomarker of hip degeneration
This study will assess [18F]-NaF uptake in PET-MRI as a novel biomarker of hip degeneration. This will be done by evaluating the presence of active bone turnover.

Determine the change in PET-MRI (SUV/T1Rho) two years after surgical correction of a symptomatic cam deformity to discern disease state.
qCT (Low Dose Computed Tomography)
Used to measure bone mineral density (mass of mineral per volume of bone) in the subchondral bone. Negative scores indicate lower bone density, and positive scores indicate higher.

Change in iHot-33 score
The International Hip Outcome Tool (iHOT-33 is a questionnaire that evaluates young active patients with early hip disease. The questionnaire is self-administered and assesses across 4 domains: symptoms and functional limitations; sport and recreational activities; job-related concerns; and social, emotional, and lifestyle concerns. Questions are answered by marking a visual analog scale between 2 anchor statements (100-mm scale). The total score is calculated as a simple mean of these responses ranging from 0 to 100, with 100 representing the best possible quality-of-life score.
Change in Hip Disability and Osteoarthritis Outcome Score (HOOS) score
Hip-specific symptoms and functional impairment will be compared using the Hip Disability and Osteoarthritis Outcome Score (HOOS). This 40-item patient reported outcome tool has 5 categories: pain, symptoms, daily living, quality of life, sports and recreational activities. Each category is scored on 100 points, 0 being the worse outcome and 100 the best outcome.
Change in EQ-5D-5L score
This questionnaire assesses generic health status. Each question is scored from 1-5, with 1 being no problems and 5 being severe problems. These scores are not aggregated. There are 5 domains: mobility, self-care, usual activities, pain and anxiety. The final question is asking the participant to self score their health that day out of 100 (0 being the worst health and 100 being the best health).
Joint Kinematics to predict hip contact forces
Retro-reflective markers will be placed on each participant in a laboratory setting. Joint kinematics will be reconstructed from marker trajectories recorded by a 10- camera system (Vicon Vantage & Vicon Vero, Oxford, UK; frequency 200 Hz). Together, with joint kinetics, the investigators will predict hip contact forces.
Joint kinetics to predict hip contact forces
Retro-reflective markers will be placed on each participant in a laboratory setting. Force platforms will record kinetic data. Together, with joint kinetics, the investigators will predict hip contact forces.

Electromyography (EMG) electrodes will be placed over the following muscles: rectus femoris, vastus medialis, vastus lateralis, tensor fascia latea, biceps femoris, semitendinosus, gluteus medius and gluteus maximus. Muscle activity will be measured using EMG signal recorded during maximum voluntary isometric contraction.

5. Study Description

Brief Summary
An abnormally formed hip joint (cam deformity) is a major cause of osteoarthritis (OA). Individuals may not experience any symptoms until OA is severe due to extensive cartilage loss and changes in underlying bone. A series of studies showed that the cam deformity can lead to the development of OA if left untreated, thus strongly suggesting a causal relationship. Currently, the cam deformity that causes pain is surgically removed to relieve the pain and treat the associated cartilage damage. Recent studies have demonstrated that surgical treatment leads to bone and cartilage changes that were related to improved function and reduced pain.
Detailed Description
This study will allow the investigators to gain a better understanding of the relationship between cartilage and bone changes. The investigators will examine adult participants in the disease state that require surgical correction and compare to age-matched controls. The investigators will look at the impact of surgical intervention through joint-specific biomarkers of OA, specifically the PET-MRI and blood/urine biomarkers, which will allow them to simultaneously query cartilage and bone activity. The investigators propose that the use of PET-MRI will give more sensitive and hip-specific information about the joint health compared to the blood/urine biomarkers in patients with symptomatic cam morphology. Participants will undergo motion analysis and 3D modeling to help the investigators better understand the disease process during the performance of specific activities and define joint contact mechanics as they relate to the PET-MRI imaging, validating a biomarker for early joint degeneration. This diagnostic tool will be extremely useful for younger individuals with a cam deformity who have not yet developed symptoms. In the future the investigators could use this to detect early degeneration in adolescents to prevent and mitigate development of OA later on. This will also help the investigators develop activity guidelines for people with smaller cam deformities in order to avoid surgery and prevent degeneration.

Arm Title
Control Group
Arm Type
Active Comparator
Arm Description
This group will consist of a matched cohort of control participants.
Intervention Type
Radiation
Intervention Name(s)
Low-dose CT Scan
Intervention Description
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.
Intervention Type
Other
Intervention Name(s)
Blood/Urine Collection
Intervention Description
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.
Intervention Type
Other
Intervention Name(s)
Patient Reported Questionnaires
Intervention Description
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.
Intervention Type
Radiation
Intervention Name(s)

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.
Intervention Type
Radiation
Intervention Name(s)

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.
Intervention Type
Other
Intervention Name(s)
Motion Analysis
Intervention Description
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.
Intervention Type
Radiation
Intervention Name(s)
3T MRI
