An observational study in Femoroacetabular Impingement Syndrome and Healthy Participants, sponsored by University of Liege. Recruiting at 1 site in Belgium. Open to participants aged 18 Years to 40 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-05-05.
Sponsored by University of Liege · Observational
The aim of this study is to identify the factors associated with successful rehabilitation following hip arthroscopy for femoroacetabular impingement syndrome and to highlight any persistent functional deficits at different key stages of rehabilitation. This is a controlled multi-observational study. The pathological hip of patients will be compared to their second healthy hip as well as to a healthy control group.
Assessments of mobility, strength, functional tests, and questionnaire submissions will take place before the intervention and 3 and 6 months after the intervention.
116 studies on the registry are indexed under Femoracetabular Impingement; 37 are open to participants now.
This study's planned enrollment of 60 is below the median of 88 across 37 observational studies indexed under Femoracetabular Impingement.

Adults aged 18-40 years will be recruited. The patient group will include individuals diagnosed with femoroacetabular impingement syndrome who are scheduled to undergo hip arthroscopy by specialized surgeons. A healthy control group without a history of hip pathology will be recruited from the local community matched as closely as possible to the patient group for demographic parameters.

Exclusion Criteria:
Muscle strength in Nm
Muscular strength is measured using a fixed dynamometer
Time frame: Pre-intervention, at 3 months and 6 months post-intervention
Hip mobility in degree
Hip mobility is measured using an electronic goniometer
Time frame: Pre-intervention, at 3 months and 6 months post-intervention
Functional results on the Y Balance Test
The functional results of the Y balance test will be measured using the composite score.
Time frame: Pre-intervention, at 3 months and 6 months post-intervention
Functional results in the single-leg squat test
The functional results of the single-leg squat test will be measured using the SIngle-leg squat Movement Performance scaLe for Individuals with FemoroAcetabular Impingement syndrome (SIMPLAI-FAI). The score on this scale ranges from 0 to 8. A higher score indicates a better functional outcome.
Time frame: Pre-intervention, at 3 months and 6 months post-intervention
Measurements of patient-reported outcomes using the Hip-Return to Sport After Injury Scale (HIP-RSI)
Analysis of scores obtained on the HIP-RSI questionnaire. This questionnaire assesses psychological readiness to resume sports activities following hip surgery. It consists of six items, and the final score ranges from 0 to 100. A higher score indicates greater psychological readiness to return to sports activities.
Time frame: Pre-intervention, at 3 months and 6 months post-intervention
Measurements of patient-reported outcomes using the International Hip Outcome Tool-12 (iHot-12) questionnaire
Analysis of scores obtained on the iHot-12 questionnaire. This questionnaire assesses the quality of life of young, active patients suffering from hip problems. It consists of 12 items and the final score ranges from 0 to 100. A score of 100 indicates full function and no symptoms, whereas a score of zero signifies maximum limitations and extreme symptoms.
Time frame: Pre-intervention, at 3 months and 6 months post-intervention
