A Novel Approach to Postsurgical Pain Management

At DFW Sports Medicine, we strive to provide patients with improved recovery after surgery, and offering the latest, unique advances in pain management helps us achieve that goal.
DFW Sports Medicine is one of the first practices in the region to adopt the novel iovera° technology that uses the body's natural response to cold to block the signaling portion of a peripheral nerve, temporarily reducing pain during the critical weeks following surgery. 1

The ioverao treatment is a focused cold therapy.  Nothing is injected into the treatment area by the ioverao system; therefore, there are no systemic side effects that are typically experienced with NSAIDs, narcotics, or other medications.  Mild localized side effects due to the ioverao treatment have been observed.

As part of this novel approach, our physician at DFW Sports Medicine is able to deliver a concentrated, focused cold zone through a portable, handheld device. This minimally invasive treatment is safe and causes no damage to surrounding tissues.2 During the simple outpatient procedure, ioverao safely and effectively allows patients with knee pain to leave their physician’s office experiencing less pain than they had when they walked in.

At DFW Sports Medicine, ioverao is being used as a part of an enhanced patient recovery protocol for certain situations.

Remember that you have a say in how your pain is treated before and after total knee arthroplasty (TKA). If you have are considering having TKA surgery, we encourage you to speak with your doctor to learn about how ioverao might be right for you.

The iovera° system is used to destroy tissue during surgical procedures by applying freezing cold. It can also be used to produce lesions in peripheral nervous tissue by the application of cold to the selected site for the blocking of pain. It is also indicated for the relief of pain and symptoms associated with osteoarthritis of the knee for up to 90 days. The iovera° system is not indicated for treatment of central nervous system tissue. The iovera° system’s “1x90” Smart Tip configuration (indicating one needle which is 90 mm long) can also facilitate target nerve location by conducting electrical nerve stimulation from a separate nerve stimulator.

Important Safety Information

The iovera° system should not be used in people with the following conditions:

  • Blood that thickens when patient is exposed to cold (cryoglobulinemia), blood appearing in the urine when patient is exposed to the cold (paroxysmal cold hemoglobinuria), skin rash that appears when patient is exposed to the cold (cold urticaria), narrowing of the blood vessels in the hands and feet when patient is exposed to the cold (Raynaud’s disease), and open and/or infected wounds at or near the treatment site

Patients being treated with the iovera° system (a needle-based therapy) may experience certain reactions, including, but not limited to:

  • Bruising, swelling, inflammation and/or redness, local pain and/or tenderness, and altered feeling at the site of application

Proper use of the device as described in the User Guide can help reduce or prevent the following reactions:

  • In the area(s) where you were treated: damage to the skin from being exposed to cold or heat, darkening or lightening of the skin, and dimples in the skin
  • Outside the area(s) where you were treated: muscles may not work or move normally
