Cryoneurolysis Versus Radiofrequency in Knee Osteoarthritis

Cryoneurolysis Versus Radiofrequency in Knee Osteoarthritis: A Randomised Controlled Trial

The project will evaluate the effectiveness of Cryoneurolysis versus radiofrequency procedures in adult patients who are resistant to traditional treatment for knee pain. They are a drug-free pain management procedure.

Study Overview

• Status: Recruiting
• Conditions: Knee Osteoarthritis
• Intervention / Treatment: Device: Cryoneurolysis; Device: radiofrequency (RF)

Detailed Description

The main approach to OA management is pain control. Cryoneurolysis versus radiofrequency in decreasing knee pain.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Group I will be treated with Cryoneurolysis; Cryoneurolysis freezes nerves	Device: Cryoneurolysis; Cryoneurolysis freezes nerves
Experimental: Group II will be treated with radiofrequency (RF); radiofrequency (RF) uses electric pulses	Device: radiofrequency (RF); radiofrequency (RF) uses electric pulses

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in visual analogue scale after intervention	Decrement (clinical improvement) in visual analogue scale (VAS) immediately after intervention. The participant's knee discomfort was measured using a VAS. Participants were asked to score their level of pain on a 100-mm horizontal line, ranging from 0 to 100.	immediately after intervention
