- Able and willing to comply with all trial tests, procedures, assessments, and follow-up visits for up to 45 days.
- Able to read and understand instructions and information presented in English.
Exclusion Criteria16
- Chronic opioid use (average ≥ 30 oral morphine equivalents / day) ≤ thirty (30) days of the TKA procedure;
- Extended-release or long-acting opioid (e.g. buprenorphine, Morphine ER, etc.) use ≤ thirty (30) days of the TKA procedure;
- History of substance abuse or misuse;
- History of significant cardiac disease (e.g. ejection fraction ≤ 50%; coronary intervention ≤ six (6) months; significant valvular abnormalities);
- Prior radiofrequency ablation or cryotherapy for pain on the operative knee;
- Prior TKA on the operative knee;
- BMI > 40;
- History of neurological, neuromuscular or neuropathic disease that would confound the study results, including chronic pain conditions;
- Have an active implanted biomedical device (such as cardiac pacemaker, insulin pump, pain stimulator, implantable cardioverter defibrillator) or cochlear \[ear\] stimulator);
- History of hip or knee dislocation or bone fractures on the operative leg;
- Sepsis or systemic infectious illness; local infection of skin or subcutaneous tissues where procedural access is required including thigh, hip or groin;
- Concomitant medical or psychiatric illness that could compromise evaluation or treatment, including anxiety (GAD-7 score >10) or depression (PHQ-9 score >15);
- Pregnant, actively planning a pregnancy or breast-feeding a child;
- Uncontrolled diabetes (A1C > 7.5%);
- History of bleeding disorder;
- Participating in another clinical trial/investigation within 45 days prior to signing informed consent.
