Peta Radiofrequency Ablation (RFA) for Knee Pain
Peta Radiofrequency Ablation (RFA) for Knee Pain, developed by Invamed—a global medical device manufacturer—addresses chronic knee pain associated with osteoarthritis or post-surgical discomfort by ablating the genicular nerves responsible for transmitting pain signals. Leveraging controlled RF energy to generate localized heat, Peta RFA reduces pain perception with minimal impact on adjacent structures, supporting improved mobility and a better quality of life for patients.
Genicular Nerve Focus
Specifically targets branches of the genicular nerves that supply the knee joint, interrupting pain transmission for long-lasting relief.
Controlled Heat Application
Radiofrequency energy (~400–500 kHz) applied at the nerve site disrupts nerve function while preserving healthy tissues and ensuring reduced post-procedure downtime.
Broad Indications
Effective in chronic osteoarthritis knee pain, patients with unsatisfactory response to conservative treatments, or post-surgical persistent knee discomfort.
Minimally Invasive
Performed under local anesthesia using a small-gauge probe inserted near the targeted nerve region; typically outpatient with rapid recovery.
Contraindications
Active knee joint infection, severe coagulopathy, or anatomical variations precluding safe probe placement; verify patient candidacy for RFA procedures.
