The most common side effects were bruising, numbness, redness, tenderness on palpation, and swelling.

Study Design: Randomized, double-blind, sham-controlled, multicenter trial with a 6-month follow-up in patients with knee OA. Patients were randomized 2:1 to cryoneurolysis targeting the infrapatellar branch of the saphenous nerve (ISN) or sham treatment (N=180; 121 in active group, 59 received sham).1

Treatment with iovera° helped patients get moving1*

  • Significant improvements in physical function demonstrated at Day 30 (P=0.001), Day 60 (P=0.04), and Day 90 (P=0.017)
  • Significant reduction in stiffness at Day 90 (P=0.03)
