Peta Radiofrequency Ablation (RFA) for Knee Pain

A precision-targeted system designed to deliver controlled radiofrequency energy for nerve ablation, effectively reducing chronic pain by disrupting pain signal transmission while minimizing impact on surrounding tissues.

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.

Radiofrequency energy (~400–500 kHz) applied at the nerve site disrupts nerve function while preserving healthy tissues and ensuring reduced post-procedure downtime.

Effective in chronic osteoarthritis knee pain, patients with unsatisfactory response to conservative treatments, or post-surgical persistent knee discomfort.

Performed under local anesthesia using a small-gauge probe inserted near the targeted nerve region; typically outpatient with rapid recovery.

Active knee joint infection, severe coagulopathy, or anatomical variations precluding safe probe placement; verify patient candidacy for RFA procedures.
