Description of intervention(s) / exposure
Arm 1: Physiotherapist-supervised rehabilitation group. Participants in the physiotherapy group will receive standard post-surgical care in addition to attending a project physiotherapist for seven treatment sessions. This will include one pre-operative visit approximately 30 minutes long and within two weeks prior to surgery. There will be six post-operative visits over 12 weeks, commencing approximately two weeks post-operatively. Each session will be an individual appointment of approximately 30 minutes. Participants in the physiotherapy group will receive a home exercise program, education and advice regarding activity, manual therapy and an unsupervised gym program.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Consecutively numbered, sealed, opaque envelopes containing group allocation will be prepared by a researcher with no other involvement in the study. The envelopes will be stored in a locked location and will be opened in sequence to reveal group allocation by a researcher not involved in recruitment or assessment of outcomes
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation schedule will be prepared by the study biostatistician using computer generated random permuted blocks of varying size, and stratified according to orthopaedic surgeon so that each surgeon contributes approximately equal numbers in each group to control for surgical variation. Participants randomised to the physiotherapy group will choose their preferred project physiotherapist according to geographical convenience.

Statistical methods / analysis
A biostatistician will oversee the blinded analyses of the data. Main comparative analyses between groups will be performed using an intention-to-treat analysis. For continuous outcome measures, differences in mean change (baseline minus follow-up) will be compared between groups using linear regression random effects modelling adjusted for baseline values of the outcome

Summary
Brief summary
Femoroacetabular impingement (FAI) is a common condition that can cause hip and/or groin pain in young active adults, as well as give rise to stiffness, muscle weakness, reduced physical function and lower quality of life. It has also been proposed as a possible risk factor for early onset of hip osteoarthritis. In symptomatic FAI, treatment often involves arthroscopic surgery. Currently, post-operative management is quite variable and dependent on surgeon preferences. Post-operative physiotherapy is not routine practice, largely because it has not been established if rehabilitation following surgery is needed to improve patient outcomes. Thus, this project primarily aims to investigate the effectiveness of physiotherapist-supervised rehabilitation following hip arthroscopy surgery for FAI in young adults.
