Can we predict who needs hip surgery? new study aims to find out
NCT ID NCT02408276
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study followed 130 young adults (35 or younger) with femoroacetabular impingement (FAI), a common cause of hip pain and early arthritis. Researchers used MRI scans and patient surveys over 5 years to see how cartilage degenerates in those treated with surgery or physical therapy. The goal is to identify which patients benefit most from each approach, helping doctors make better treatment decisions.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors decide which patients benefit most from hip surgery versus physical therapy for FAI.
- What could go wrong
- This is an observational study, not a treatment trial. It may not lead to clear treatment guidelines, and results may not apply to all patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * All patients 35 years of age or younger enrolled in the HSS Hip Preservation Registry prior to September 30, 2016 with an MRI confirmed diagnosis of FAI will be eligible for inclusion in this study regardless of surgery status. * Patients who agree to participate must complete a baseline questionnaire consisting of: 1) Modified Harris Hip Score (MHHS), an overall measure of hip condition; 2) the Hip Outcome Score (HOS), a measure developed specifically for younger active patients that measures quality of life and levels of sports and recreation; and 3) International Hip Outcome Tool (iHOT33), a newly developed hip specific outcome score, which measures a number of subscores relating to physical and social functioning with hip problems. Exclusion Criteria: * Patients over age 35 will be excluded as the focus of this study is early changes that may predispose to later degenerative changes. * Patients undergoing revision hip arthroscopy as their first treatment in the Registry will not be eligible, as these are patients who have failed initial therapy. * Patients with no complete questionnaires at any time point will be excluded.
