| Secondary | Change in PROMIS - Quality of Life Score | Each question has five response categories ranging in value from 1 to 5. The min and max response within each question is 1 and 5, respectively. The total raw score is calculated as the sum of the values of the responses to each question. The total raw score is then translated into a T-score for each participant. The T-score rescales the raw score into a standardized T-score with a mean of 50 and a standard deviation (SD) of 10. Higher scores within the Physical Function and the Ability to Participate in Social Roles/Activities domains indicate better patient-reported health status. Lower scores within the Anxiety, Depression, Fatigue, Pain Interference, Sleep Disturbance, and Pain Intensity indicate better patient-reported health status. | Of the 108 study subjects who had a study index procedure, 3 of these study subjects were intra-operative screen failures leaving an analysis population of 105.

| Secondary | Change in Quality of Life - MOxFQ | This instrument has 16 questions, each question has 5 response categories with scoring 0 to 4 where 0 represents the least problems and 4 represents greatest problems. The min and max response within each question is 0 and 4, respectively. The maximum possible raw score for the Walking/Standing domain is 28. The maximum possible raw score for the Pain domain is 20. The maximum possible raw score for the Social Interaction domain is 16. Scores for each domain are calculated separately, as the sum of each individual item (raw) score within that domain. In each case, this is then converted to a metric of 0 - 100 (higher score representing greater severity). Scores for the MOXFQ Index are initially calculated as the sum of all 16 individual item (raw) scores (maximum possible raw score 64). This is then converted to a metric of 0 - 100 (higher score representing greater severity). | Of the 108 study subjects who had a study index procedure, 3 of these study subjects were intra-operative screen failures leaving an analysis population of 105.
