Brief 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. 1.Hip muscle function
2. 2.Single leg jump performance
3. 3.Self-reported hip and groin function
4. 4.Evaluation of return to sport
5. 5.Evaluation of satisfaction regarding usual-care post-operative rehabilitation

Conditions

Femoroacetabular Impingement

Outcome Measures

Primary Outcomes (3)

• Peak force

  Peak isometric hip torque (Nm/kg) of abduction, adduction, extension, and flexion

  Baseline (week 0)

• Rate of force development

  0-100 ms and 0-200 ms rate of torque development (Nm/s/kg) of abduction, adduction, extension, and flexion

  Baseline (week 0)

• Self-reported hip and groin function (subjects included in prospective study)

  Obtained using the Copenhagen Hip and Groin Outcome Score (HAGOS); Scale from 0 (extreme hip and groin problems) to 100 (no hip and groin problems)

  Baseline (week 0) and follow-up (week 12)

Secondary Outcomes (7)

• Single leg jump performance

  Baseline (week 0)

• Self-reported hip and groin function

  Baseline (week 0)

• Return to sport

  Baseline (week 0)

• Satisfaction regarding usual-care post-operative rehabilitation

  Baseline (week 0)

• Change in Peak force (subjects included in prospective study)

  Baseline (week 0) and follow-up (week 12)

Study Arms (1)

FAIS group

Subjects who have had a hip arthroscopy for femoroacetabular impingement during the preceding 6-30 months

Other: Testing of performance

Interventions

Testing of performance OTHER

The cross-sectional evaluation will involve assessment of: 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 The exercise-based treatment will involve criteria-based physiotherapy aiming at improving muscle function around the hip and trunk.

Also known as: Exercise-based treatment
