An Evaluation of Hip Preservation Outcomes

iHOT-12 is a 12-item questionnaire scored using a visual analog scale from 0 to 100, with a score of 100 being the best function and least amount of symptoms, and the overall mean equates to the final iHOT score.

The HOS is a self-administered questionnaire with a scoring system composed of 2 sub-scales. The 19 item Activities of Daily Living (ADL) sub-scale and a 9 item Sports sub-scale. Both have a range of scores from 0 to 4, with 0 being 'unable to do' and 4, 'no difficulty'. N/A is also an option. The total score for each is multiplied by 4 with the highest potential ADL score bing no greater than 68 and the sports scale with the highest potential score being 36. An overall higher score from both sub-scales indicates a greater level of function.

PROMIS Physical function is a standardized computer adapted test which is able to quickly and effectively score patients on a scale of 0 (not able to function) to 100 (fully functional) based on their physical function. 100 would be a perfect score and 0 would be the worst possible score. Higher scores indicate better physical function.

The Chicago sports score asks athletes questions pertaining to their ability to return to sport. If they are able to return to sport it asks questions about their ability level since returning. Similarly, if they are not able to return to sport it asks questions regarding what has held them back. It is on a 100 point scale with 100 being the best possible outcome and 0 the lowest possible score. Higher scores indicate better ability to return to sports.

Participants will be asked to estimate their pain on a VAS from 0 to 10, where 0 is considered to be no pain at all and 10 is considered to be the worst possible pain.

Participants will receive the PROMIS pain interference, physical function, and global health modules to assess quality of life, a commonly used general health quality of life assessment tool. PROMIS pain interference is a standardized computer adapted test which is able to quickly and effectively score patients on a scale of 0-100 based on how pain affects their day to day life. 100 would be a perfect score and 0 would be the worst possible score. Higher scores indicate less pain interference on quality of life.

The PROMIS Global-10 is a 10-item patient-reported questionnaire that measures changes in general health in which the response options are presented as 5-point scale, 5 (without any difficulty) to 1 (Unable to do). Higher scores indicate a healthier patient.

Participants will be asked to rate their level of satisfaction after surgery with 10 being extremely satisfied and 0 being not satisfied at all.

Participants will be asked anchor questions which will be used to determine psychometric thresholds of success the psychometric threshold substantial clinical benefit (SCB). They will be asked whether they feel that their current symptoms are acceptable or not to them. This helps to establish the patient acceptable symptomatic state (PASS). They will also be asked whether they feel that their hip is better worse or no different compared to before surgery. This will establish the psychometric threshold SCB.
