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. Symptoms of hip pain - patients may also have symptoms of clicking, catching or giving way 3. Radiographic evidence of pincer- or cam-type FAI on plain radiographs confirmed with cross-sectional imaging, defined as alpha angle >55° or lateral centre edge angle >40° 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

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. Previous significant hip pathology such as Perthes' disease, slipped upper femoral epiphysis, or avascular necrosis 3. Previous hip injury such as acetabular fracture, hip dislocation or femoral neck fracture 4. Previous shape changing surgery (open or arthroscopic) in the hip being considered for treatment

Design outcomes

Primary

MeasureTime frame
Clinical effectiveness of hip arthroscopy, assessed by patient-reported hip-specific quality of life after one year

Secondary

MeasureTime 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
