Overview
Brief Summary
The purpose of this study is to determine the effectiveness of pulsed radio frequency (PRF), a type of electromagnetic field treatment with the Ivivi Torino II for reducing post-operative narcotic use in patients recovering from Total Knee Arthroplasty.
Detailed Description
Surgeons are continually looking for means to minimize postoperative pain following TKA in order to reduce or eliminate the need for opioid pain medications. Reductions in pain and edema along with improvements in range of motion encourage quicker recovery of joint function and normal activities. Pulsed radio frequency (PRF), a type of electromagnetic field treatment is proven to effectively modulate postoperative pain and edema in plastic surgery. Therefore, PRF has potential as an adjunct therapy for patients recovering from TKA. The purpose of the current double-blind, randomized, sham-controlled clinical trial is to determine the effectiveness and safety of the Ivivi Torino II, a device that delivers pulsed radio frequency (PRF), a type of electromagnetic field treatment, in patients recovering from TKA for treatment of severe knee OA.

Outcomes
Primary Outcomes
The average daily morphine equivalent dose consumption at 2 weeks post-surgery.
Time Frame: 2-week follow-up period from surgery
Secondary Outcomes
- 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)
- Adverse Events collected and analyzed for confirmation of device safety(Randomization to 4 weeks post-surgery)
