Eligibility
Inclusion criteria
Inclusion criteria: Inclusion criteria as of 15/03/2016: 1. Age =16 (no upper age limit) 2. Symptoms of hip pain - patients may also have symptoms of clicking, catching or giving way 3. Radiographic evidence of pincer- and/or cam-type FAI morphology on plain radiographs and cross-sectional imaging, defined as: 3.1. Cam morphology - an alpha angle >55º; 3.2. Pincer morphology - a lateral centre edge angle of >40 degrees or a crossover sign on the anteroposterior radiograph of the pelvis 4. The treating surgeon believes the patient would benefit from arthroscopic FAI surgery 5. The patient is able to give written informed consent and to participate fully in the interventions and follow-up procedures Original inclusion criteria: 1. Age =16 (no upper age limit) 2.

The treating surgeon believes the patient would benefit from arthroscopic FAI surgery 5. The patient is able to give written informed consent and to participate fully in the interventions and follow-up procedures
Exclusion criteria
Exclusion criteria: 1. Evidence of pre-existing osteoarthritis, defined as Tonnis grade >1, or more than 2 mm loss of superior joint space width on AP pelvic radiograph 2.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Clinical effectiveness of hip arthroscopy, assessed by patient-reported hip-specific quality of life after one year | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. General health status and health-related quality of life after 12 months 2. Pattern of clinical change over 12 months 3. Patient satisfaction with treatment and outcome after one year 4. Number and severity of adverse events after treatment 5. Need for further procedures up to three years 6. Cost-effectiveness within the trial and for a patient's lifetime 7. Develop and report processes to optimise recruitment in an RCT or surgery versus non-operative care 8. Fidelity of delivery of interventions | — |
