Mobility, Strength, and Functional Outcomes Before Surgery, at 3 Months, and at 6 Months After Hip Arthroscopy for Femoroacetabular Impingement Syndrome

Condition(s) studied

Study summary

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.

Eligibility

Primary outcome measure(s)

• Muscle strength in Nm — Pre-intervention, at 3 months and 6 months post-intervention
  Muscular strength is measured using a fixed dynamometer
• Hip mobility in degree — Pre-intervention, at 3 months and 6 months post-intervention
  Hip mobility is measured using an electronic goniometer
• Functional results on the Y Balance Test — Pre-intervention, at 3 months and 6 months post-intervention
  The functional results of the Y balance test will be measured using the composite score.
• Functional results in the single-leg squat test — Pre-intervention, at 3 months and 6 months post-intervention
  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.
• Measurements of patient-reported outcomes using the Hip-Return to Sport After Injury Scale (HIP-RSI) — Pre-intervention, at 3 months and 6 months post-intervention
  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.
• Measurements of patient-reported outcomes using the International Hip Outcome Tool-12 (iHot-12) questionnaire — Pre-intervention, at 3 months and 6 months post-intervention
  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.
