Impact of Noninvasive Targeted Pulsed Electromagnetic Field (tPEMF) on Opioid Use, Pain, and Joint Function Following Total Knee Arthroplasty

Detaillierte Beschreibung
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.

Post-surgical opioid use during hospitalization and following discharge at 1 and 4 weeks post-surgery.
Zeitfenster: 1 and 4 weeks post-surgery
|
1 and 4 weeks post-surgery
|
|
Knee pain severity assessed on a 10 cm visual analogue scale (VAS)
Zeitfenster: At intervals over the 4-week follow-up period
|
Knee pain will be assessed for "current", pain at the time of data collection and "maximum", maximum pain experience at any point during the day of evaluation
|
At intervals over the 4-week follow-up period
|
The measurement of knee joint circumference
Zeitfenster: Measurement performed preoperatively, on the first or second postoperative day, at the discharge dressing change, and at the 4 week follow-up visit
|
With patient in supine position, the circumference of the extended knee will be measured 1 cm proximal to the base of the patella using the same type of tape measure in all patients
|
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
Zeitfenster: 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
|
Range of motion will be assessed using the knee flexion technique, which allows the use of a goniometer with the trans-epicondylar axis of the knee joint as the fulcrum.
|
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
Zeitfenster: 4 weeks post-surgery
|
Subjects will be required to track daily OA-related medication use including analgesics, anti-inflammatories, and other non-opioids using a daily diary.
|
4 weeks post-surgery
|
Adverse Events collected and analyzed for confirmation of device safety
Zeitfenster: Randomization to 4 weeks post-surgery
|
Subjects will be instructed by the research staff and in the instructions in the daily diary to contact the research staff and/or investigator with any adverse events (AEs).
Adverse events will be recorded daily.
