Coolief Radiofrequency Ablation (RFA) is a minimally invasive procedure used to treat chronic pain, particularly in the knee, hip and spine. It involves using radiofrequency energy to target and disrupt nerve pathways that transmit pain signals.
How Does It Work?
- Preparation: The procedure is performed under sedation or a light general anaesthetic. The area where the procedure will be performed will be cleaned and sterilized.
- Placement of Probes: Small, thin probes are inserted through a needle-like device into the area around the nerve. Xray fluoroscopy is used to guide the probes accurately.
- Radiofrequency Energy Application: Once the probes are correctly positioned, radiofrequency energy is delivered to the nerve. This energy generates heat, which disrupts the nerve’s ability to send pain signals. A test dose is administered initially to ensure that your motor nerves remain unaffected during the procedure.
- Completion: After the procedure, local anaesthetic is injected around the area and the probes are removed, and a dressing is be applied to the insertion sites. You will be monitored for a short period before being discharged.
What to Expect After the Procedure:
- Recovery: You may experience some discomfort or soreness at the treatment site, which usually resolves within a few days. Pain relief can take a few weeks to become noticeable.
- Activity: Most patients can resume normal activities within a day, but you should avoid strenuous activities or heavy lifting for a short period.
- Follow-Up: A follow-up appointment will be scheduled to assess the effectiveness of the treatment and to discuss any further care if needed.
Benefits:
- Pain Relief: Many patients experience significant relief from chronic pain that has not responded well to other treatments.
- Minimally Invasive: The procedure is less invasive compared to surgery and involves a shorter recovery time.
Risks and Considerations:
- Possible Side Effects: These may include temporary swelling, bruising, or numbness at the treatment site.
- Infection: As with any procedure, there is a small risk of infection at the insertion sites.
- Limited Effectiveness: While many patients benefit from Coolief RFA, it may not provide complete pain relief for everyone.
