This article compares two approaches side by side to clarify how they differ in principle and practice. Interventional pain management, sometimes called algology, addresses chronic back, neck, joint, and tumor-related pain that has not responded adequately to conservative measures. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Chronic Pain Managed with Interventional Radiofrequency Techniques
Interventional pain management, sometimes called algology, addresses chronic back, neck, joint, and tumor-related pain that has not responded adequately to conservative measures. Common targets include the medial branch nerves supplying the facet joints of the spine, the sacroiliac region, and peripheral nerve branches such as the genicular nerves around the knee. Thermal RF creates a heat lesion to interrupt pain transmission, while pulsed RF applies energy in bursts intended to modulate the nerve without the same degree of thermal lesioning.
Radiofrequency ablation vs Steroid injections: Key Differences
Steroid injections deliver anti-inflammatory medication around a painful structure and may provide temporary relief in some patients. Radiofrequency ablation instead uses energy to lesion or modulate the nerve carrying the pain signal, aiming for a longer-lasting effect. Diagnostic blocks are often used before RF to confirm the pain source, whereas injections may serve both diagnostic and therapeutic roles. The choice between them is individualized and determined by the pain specialist based on the diagnosis.
How INVAMED Supports Both Approaches
INVAMED's pain management portfolio centres on radiofrequency lesion generators and electrode systems, organized by the anatomical target and the type of RF energy delivered. Procurement teams should confirm local regulatory registration and indication status, which vary by market. For pain units and distributors, INVAMED positions a radiofrequency portfolio spanning spinal, sacroiliac, knee, and intraosseous applications.
Key Considerations
- INVAMED pain management devices are for use by trained pain specialists under imaging guidance and per the instructions for use.
- Real-time feedback on temperature, impedance, and lesion size is intended to support safe energy titration during RF procedures.
- Because sensory nerves can regenerate, repeat treatment may be considered over time, based on the return of symptoms.
Frequently Asked Questions
Can RF ablation be repeated if pain returns?
Because treated sensory nerves can regenerate, a repeat procedure may be considered in appropriate cases; the timing is an individualized clinical decision.
What is the regulatory status of these RF devices?
Regulatory status such as European market authorization and manufacturing standards are stated in the product documentation and depend on local registration by market.
How long does RF ablation relief last?
The literature commonly cites facet-related relief of about 6 to 12 months, but duration varies by patient and target and is discussed with the treating specialist.

Clinical and Technical Context
The choice between pulsed and thermal modes is made by the pain specialist for the specific target. Its use is planned individually as part of a broader oncological and pain management strategy. The literature commonly cites facet RF relief in the range of about 6 to 12 months, but individual duration varies and is not guaranteed. Candidacy and target selection are determined by the treating clinician following assessment. The INVAMED Peta Radiofrequency Ablation (RFA) for Knee Pain is positioned specifically for this knee application. Whether an RF procedure is appropriate, and which target is selected, is a clinical decision made by a pain specialist after diagnostic assessment. Generator settings are managed by the operator according to the target and the device instructions for use. Real-time feedback on temperature, impedance, and lesion size is intended to support safe energy titration during RF procedures.
