Center for Hip Preservation

Ongoing Research at the Center for Hip Preservation


Our Center researchers are establishing a clinical database to evaluate diagnosis and treatment options that will benefit our patients as well as the outside world. Researchers are focusing on new ways and techniques to treat hip pain. One of the goals of the Center's research will be to learn if hip arthroscopy will change the course of arthritis. Research will look deeper into the underlying causes of osteoarthritis of the hip through imaging and biomechanical studies and focus on new surgical techniques and hip preserving procedures.

Clinical Trial: To Understand the Reason for Motion Limitations in Patients with FAI

The Motion and Muscle Analysis in Individuals with Femoral Acetabular Impingement: A Pilot Study

Femoroacetabular Impingement (FAI) occurs when the ball (head of the femur) does not have full range of motion in the socket (acetabulum of the pelvis) due to excess bone. The resulting friction in the hip joint can cause damage to the soft tissue that lines the socket. People with FAI experience pain during common daily activities such as sitting, stair climbing, and even walking. It is currently unclear how the abnormal bone and soft tissue injury affect the muscles around the hip, and why this causes a change in walking patterns and movement.

The Motion and Muscle Analysis in Individuals with Femoral Acetabular Impingement: A Pilot Study will help to better understand how selected hip muscles contribute to different motions. Subjects enrolled in the study, including people with FAI and people with normal anatomy are tested at the Leon Root, M.D Motion Analysis Lab. Reflective markers and electrodes are attached to the body so motion can be recorded on video and electrical activity from muscles can be measured during walking, stair climbing, and other exercise type activities.

Understanding the reason for motion limitations in patients with FAI will help to develop more effective nonsurgical treatments and postoperative rehabilitation plans.

This research study is currently recruiting both healthy male volunteers age 18-46 and males age 18-45 who have been diagnosed with FAI.


Our registry will enable our clinicians to analyze clinical, radiographic and imaging data on patients to document outcomes for two, five, ten and twenty years following treatment. The registry will help investigators learn which patients make the best candidates for hip arthroscopy and will aid in the development of optimal standards of care and treatment, as well as offer non-operative solutions.
