Arthritis Clinical Trials

The investigators are conducting a research study to determine if the Torino II, a pulsed electromagnetic fields (PEMF) device is helpful in reducing postoperative pain and swelling after total knee replacement surgery. Postoperative pain and swelling may cause discomfort that may directly influence functional recovery after surgery. By reducing pain and swelling immediately following surgery,the use of high doses of narcotic, NSAID, and Tyelenol pain killers can be reduced, and possibly avoided. Recovery can be maximized, as well.

The PEMF device that is being used (the Torino II) is distributed by Ivivi Health Sciences, and has been approved by the FDA for the treatment of pain and swelling following surgery. The device is non-invasive, and is fixed onto the outside of the dressing with Velcro straps. The device will give off electromagnetic pulses to target pain relief in the knee. PEMF devices have been in clinical use for decades, and to date, no reported side effects have occurred.

It is important to note that treatment will still follow the standard Meritus Medical Center protocol for knee replacement surgery. This includes pain medication, icing, and physical therapy. This standard protocol will be followed no matter what study group patients are assigned to. Participation in this study or lack thereof will not change the treatment protocol.
