Muscular and Functional Performance in FAIS Patients

Denmark45 participantsStarted 2018-09-13

Plain-language summary

Following hip arthroscopy for femoroacetabular impingement syndrome (FAIS) decreased hip muscle strength for adduction, extension, flexion, and external rotation including impaired functional performance have been observed. However, no studies are lacking on more demanding muscular and functional parameters such as hip muscle rate of force development and reactive strength index. Information on such muscular properties following hip arthroscopy for FAIS may help guide future planning of post-operative rehabilitation strategies. This is a cross-sectional study with an embedded prospective non-randomized study. The aim of the cross-sectional study is to investigate hip muscle function and functional performance in patients who have undergone hip arthroscopy for FAIS during the preceding 6-30 months. The aim of the prospective non-randomized study is to investigate the effect of a 12-week structured and supervised physiotherapy-led intervention aiming at improving hip muscular function on self-reported hip and groin function including hip muscle function and functional performance. Forty-five subjects from the Capital Region with an age of 18-40, who have undergone a hip arthroscopy for FAIS during the last 6-30 months, will be included in the cross-sectional study. Additionally, all included subjects will be offered to take part in the prospective non-randomized study consisting of 12 weeks of supervised and structured physiotherapy-led treatment. The below measures will be obtained at baseline, and at 12-weeks follow-up if subjects are included in the prospective study. All testing, and supervised physiotherapy-led treatment, will be performed at Hvidovre Hospital: 1. Hip muscle function 2. Single leg jump performance 3. Self-reported hip and groin function 4. Evaluation of return to sport 5. Evaluation of satisfaction regarding usual-care post-operative rehabilitation

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Male/female at the age of 18-40 years at the time of surgery * Undergone hip arthroscopy for FAIS during the previous 6-30 months (surgical procedure: cam resection and labral surgery) * Pre-operative cam morphology specified as an alpha angle ≥55° Exclusion Criteria: * Pre-surgery joint space width \<3 mm * Any of the following surgical procedures at any time: extra articular surgery of the hip joint (except capsular closure), microfracture, periacetabular osteotomy, and surgery of the ligamentum teres; previous hip arthroscopy in the same hip joint; previous hip pathology such as Perthes' disease, slipped upper femoral epiphysis, hip dysplasia (Lateral Center Edge Angle \<25°), and/or avascular necrosis; Any rheumatoid disease in the hip joint such as synovial chondromatosis.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
