What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Harris HIp Score (HHS) | measures pain, function, absence of deformity and range of motion after hip surgery. This is performed by a qualified health care provider. The higher the score, the better the outcome. | 2 years | 
| Hip Disablity and Osterarthritis Outcome Score (HOOS) | Scoring from 0-100 with 0 indicating the worst possible hip symptoms and 100 indicating no symptoms. This tool assesses patients opinion of their hip and associated problems, evaluate symptoms and functional limitations. There are 40 items assessing 5 subscales of: Pain, symptoms, activities of daily living (ADL), function in sport and recreation and Hip related quality of life. | 2 year | 
| HOOS Jr. | Scoring from 0-100 with 0 indicating the worst possible hip symptoms and 100 indicating no symptoms. This tool assesses patients opinion of their hip and associated problems, evaluate symptoms and functional limitations. this version is shortened to 6 questions assessing function, pain and quality of life. | 2 year |
