Outcome Measures
Primary Outcomes (1)
The average daily morphine equivalent dose consumption at 2 weeks post-surgery.
2-week follow-up period from surgery
Secondary Outcomes (6)
Post-surgical opioid use during hospitalization and following discharge at 1 and 4 weeks post-surgery.
1 and 4 weeks post-surgery
Knee pain severity assessed on a 10 cm visual analogue scale (VAS)
At intervals over the 4-week follow-up period
The measurement of knee joint circumference
Measurement performed preoperatively, on the first or second postoperative day, at the discharge dressing change, and at the 4 week follow-up visit
Range of motion of the knee joint, assessed using the knee flexion technique
Assessed preoperatively, on the first or second postoperative day, at the discharge dressing change (unless discharged within 2 days), and at the 4 week follow-up visit
OA-related medication use including analgesics, anti-inflammatories, and other non-opioids
4 weeks post-surgery
- +1 more secondary outcomes

- Advanced hip, spine, or ankle osteoarthritis that significantly limits ambulation
- Subjects who have any implanted metallic leads, wires, or systems (e.g. pacemaker, implantable cardioverter-defibrillator)
- Use of narcotic pain medication for any condition in the last 1 month prior to surgery
- Self-reported diagnosis of post-traumatic or inflammatory arthritis (e.g. rheumatoid or psoriatic)
- Pregnant or lactating female
- Participation in any clinical trial in the past 30 days
- Vulnerable populations including prisoners and nursing home residents
- Any medical condition that, in the opinion of the investigator, may compromise patient safety or confound the assessment of treatment effectiveness
