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.

Inclusion Criteria:

• Subjects with femoroacetabular impingement syndrome, with corresponding clinical symptoms and signs, as well as validation by imaging
• Subjects who have already consulted a surgeon specializing in hip arthroscopic surgery and whose surgery is planned to treat femoroacetabular impingement syndrome
• Subjects aged between 18 and 40

Exclusion Criteria:

• History of rheumatic disease, dysplasia or pediatric disease affecting the hip (Legg-Calvé; superior femoral epiphysiolysis)
• Subject who has already undergone surgery on the hip joint
• Subjects with a history of injury to the muscles involved in the assessments within the last year

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.

The principal investigator behind the study project will be the only person to process the data collected during this study. There are no plans to share this data.
