Official title
Mobility, Strength, and Functional Outcomes Before Surgery, at 3 Months, and at 6 Months
Overview
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.
Primary outcome measures
- Muscle strength in Nm [Time frame: Pre-intervention, at 3 months and 6 months post-intervention]
- Hip mobility in degree [Time frame: Pre-intervention, at 3 months and 6 months post-intervention]
- Functional results on the Y Balance Test [Time frame: Pre-intervention, at 3 months and 6 months post-intervention]
- Functional results in the single-leg squat test [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) [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 [Time frame: Pre-intervention, at 3 months and 6 months post-intervention]
Eligibility criteria
Inclusion criteria
