Hip disability will be assessed using the Harris Hip Score. The questionnaire is one of the most commonly used hip scores for assessment of hip function. It comprises of 10 sections: Pain, Support, Limp, Distance walked, Stairs, Public Transportation, Sitting, Putting on Shoes/Socks, Presence of Deformity and Range of Motion (flexion, extension, abduction, adduction, internal and external rotation. The score of these items are summed together to get the total score. Scoring can range from 0 to 100. Scores less then 70 are poor, scores 70 to 79 are fair, scores 80 to 89 are good, and scores 90 to 100 are excellent.

Health status will be assessed using the RAND-36 Health Survey. The survey contains eight concepts: physical functioning, bodily pain, role limitations due to physical health problems, role limitations due to personal or emotional problems, emotional well-being, social functioning, energy/fatigue, and general health perceptions. It also includes a single item referring to a perceived change in health. A high score defines a more favorable health state. In addition, each item is scored on a 0 to 100 range. The lowest and highest possible scores are 0 and 100, respectively. Scores represent the percentage of total possible score achieved.

Patient-reported activity level will be assessed using the UCLA questionnaire. The index is self-administered and assesses current activity level. The UCLA scale is a simple scale ranging from 1 to 10. A low number (1) signifies very low activity levels, whereas 10 signifies a high activity level. One number is selected to best reflect the participants current activity level.

Patient-reported hip functionality will be assessed using the WOMAC questionnaire. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) is widely used as a standard assessment of arthritis in the hip joint. The Index is self-administered and assesses the three dimensions of pain (5 items), joint stiffness (2 items), and Physical Function (17 items) in hip osteoarthritis using 24 questions. The Likert Scale uses the following descriptors for all items: none, mild moderate, severe, and extreme. These correspond to an ordinal scale of 0-4. Scores are summed with higher scores indicating worse pain, stiffness, and function.
