Prior or current presence of hardware in index knee other than screws from previous ligament repair that do not require manipulation or removal for TKR surgery
Other planned major surgery within 12 months of study surgery
Concurrent painful physical condition that is unrelated to the study knee (e.g., back, shoulder or contralateral knee pain) that will require analgesic treatment, such as NSAIDs or opioids, during study follow-up
Current NRS pain intensity in the contralateral knee with a severity ≥ 4
Current or historical evidence of any clinically significant disease or condition, especially cardiovascular, pulmonary or neurological, that, in the opinion of the Investigator, may increase the risk of surgery or complicate or affect the subject's study follow-up
Suspected opioid abuse in the last 12 months with a score exceeding 5 on the DAST-10 questionnaire, and/or taking opioids ≥ 46 of the previous 90 days, and currently taking >90 mg in morphine milligram equivalents (MME) at least 5 days per week in the month prior to screening.
History of alcohol abuse within previous 12 months (score of 4 on CAGE questionnaire)
Anxiety Sensitivity Index (ASI) score >40
Fear of Pain Score (FPQ-III) score >120

History of coronary or vascular stent placed within 3 months
Had a malignancy in the last 12 months, except for non-metastatic basal cell or squamous cell carcinoma of the skin or localized carcinoma in situ of the cervix
Positive urine drug screen for disallowed medication pre-operatively on day of study surgery
