Dr Vinod Dasa introduces the use and history of cryotherapy, also known as cryoneurolysis, and how iovera˚ targeted cold therapy using nitrous oxide provides a safe and effective treatment option at -88˚C.

Considering Knee Anatomy for Treatment of Pain

Dr Pieter Vreede identifies the stretch of an incision site after total knee arthroplasty as a core component to the pain experienced by a patient during postsurgical recovery.

Nerve Anatomy Related to the iovera MOA Versus Other Modalities

System Setup Guide

 

Instructions on setup, priming, attaching Smart Tips, and replacing Cartridges. Please see the full user guide for detailed instructions.

MOA Video

 

The iovera° treatment works by applying targeted cold to a peripheral nerve. The effect of this treatment is immediate and can last up to 90 days.

Superficial Genicular Pre-TKA Case Report With Smart Tip 190

report case

A case report featuring Dr Josh Urban performing superficial genicular treatment prior to a Total Knee Arthroplasty using the Smart Tip 190 under ultrasound.

IndicationThe 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

ContraindicationsThe iovera° system is contraindicated for use in patients with the following:

  • Cryoglobulinemia, paroxysmal cold hemoglobinuria, cold urticaria, Raynaud’s disease, and open and/or infected wounds at or near the treatment site

Potential ComplicationsAs with any surgical treatment that uses needle-based therapy and local anesthesia, there is a potential for site-specific reactions, including, but not limited to:

  • Ecchymosis, edema, erythema, local pain and/or tenderness, and localized dysesthesia

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

  • At the treatment site(s): injury to the skin related to application of cold or heat, hyper- or hypopigmentation, and skin dimpling
  • Outside the treatment site(s): loss of motor function
