Iovera Nerve Block Injections
Dr. Durkin uses Iovera nerve block injections to help with anterior and incision pain post-operatively for patients with knee replacements. Iovera treatment 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. The nerves that are blocked are the infrapatellar branch of the saphenous nerve and anterior femoral cutaneous nerve. These nerve blocks are only sensory and do not inhibit motor control. The Iovera treatment takes approximately 30 minutes per knee and is done typically 10-14 days before knee replacement surgery. Patients have experienced pain relief up to 3 months after the Iovera Treatment.
In a clinical study, comparing patients who were treated with Iovera prior to total knee replacements vs those who were not treated with Iovera showed that the Iovera treated patients:
- Requested less opioids, but reported similar function and pain scores
- Experienced less stiffness at 6 and 12 weeks post-op
- Experienced less knee pain at 6 and 12 weeks post-op
