Description of intervention(s) / exposure
Interventions
Each participant will be treated by experienced physiotherapists who will be trained and proficient in both interventions (physiotherapy; education).

Physiotherapy
The physiotherapy intervention will be delivered in 8 sessions each of 30 minutes duration over 3-months (1/week for 4 weeks, 1/fortnight for 8 weeks). This consists of (i) manual hip joint and soft tissue mobilisation and stretching; (ii) hip muscle retraining; (iii) trunk muscle retraining; (iv) functional, proprioceptive and sports- or activity- specific retraining; (v) enhancing physical activity; and (vi) education. Education will consist of topics including exercise, weight loss if appropriate, and appropriate stretching. This will be provided during thwe physiotherapy session. Based on our pilot data, the treatment will be tailored according to each patient’s clinical presentation (e.g. strength, pain severity, sporting and functional needs), presence of co-morbidities (e.g. back and other lower-limb pain or pathology) and progressed based on response to exercise load, thus maximising the training effects. The physiotherapist will supervise exercises during each visit for 15 minutes. A home exercise program will be performed independently at home 4 times per week for 60 minutes per session. An exercise manual will be produced and made accessible to each participant. Participants will complete a self report diary which will be checked at each visit and include adherence to home exercise program, use of medications and additional activity undertaken.

Comparator / control treatment
Education
In order to control for the psychosocial contact inherent with the physiotherapy treatment, the education group will encompass individualised health education sessions covering topics such as exercise, diet, weight loss and appropriate stretching, in a similar fashion to previously published clinical trials looking at physiotherapy management in older people with advanced hip OA. The information sheets will be modified to be appropriate for this younger age group. The control sessions will be provided with the same frequency and duration as the physiotherapy sessions.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants will be identified by the surgeon, and invited to contact the Project co-ordinator. Volunteers will be screened via telephone interview, followed by a clinical examination to confirm eligibility. The randomisation schedule (permuted blocks of varying sizes), generated and maintained centrally by the University of Queensland, School of Health and Rehabilitation Sciences, will be revealed via telephone following baseline assessment. The blinded researcher will perform outcome assessments at baseline and 3 months, and participants will be instructed not to divulge their group allocation to the assessor. The research group will access patient’s past medical and surgical records to obtain details of surgical intervention and pre-operative radiological findings.

Statistical methods / analysis
The primary outcomes measured at 3 months will include recruitment rate, compliance with all aspects of intervention and drop-out rate. Secondary outcomes will be analysed using linear mixed regression models, including their respective baseline scores as a covariate, subjects as a random effect, treatment condition as a fixed factor and the covariate by treatment interaction. Participant characteristics (e.g.; gender, age) will be included as covariates. We aim to detect the minimum clinically important improvement on this outcome as reported by Kemp et al.

Summary
Brief summary
Hip osteoarthritis (OA) is associated with significant personal and societal burden, which is rising with increased life expectancy. Early hip OA is commonly seen during hip arthroscopic surgery, and can affect younger adults (age<55 years) with peak work and family commitments. Whilst hip arthroscopy is commonly undertaken for pain associated with early hip OA, no studies have examined best practice for post-operative rehabilitation. An effective intervention for early-onset hip OA will potentially have great personal and societal impact. The primary aim of this study is to establish the feasibility of a randomised clinical trial (RCT) of physiotherapy, targeted to improve hip joint range and hip-related symptoms in early-onset hip OA. This study is a blinded pilot RCT conforming to CONSORT guidelines. Twenty people with early hip OA who had hip arthroscopy surgery six to 12 months previously will be recruited and randomized to the intervention group (individualized manual therapy, exercise therapy and education) or the control group (education only). Eight interventions will occur for both groups over three months, with outcomes collected at baseline and three months. Primary outcome measure - feasibility of a full scale RCT. Secondary outcome measures - symptoms, quality-of-life and range-of-motion.
