For patients with end-stage degenerative knee arthritis, artificial joint surgery is a representative treatment that can be expected to alleviate pain and restore function. However, there are cases where pain persists for a long time even after surgery. The medical community classifies this as 'Persistent Postoperative Pain (PPP)' and is exploring management strategies.

Radiofrequency Genicular Nerve Ablation is gaining attention as an alternative. This procedure involves accurately identifying the nerve areas associated with pain using imaging equipment, and then delivering radiofrequency energy to alleviate the pain. It does not require incisions and is often performed under local anesthesia, placing a low burden on the patient. However, since its applicability and effectiveness may vary depending on the patient's condition, an accurate assessment by a specialist is essential.

Medical professionals both domestically and internationally are actively conducting research to evaluate the applicability of radiofrequency nerve treatment for patients with persistent pain following knee artificial joint surgery. While some studies have proven its effects on pain relief and functional improvement, patient responses have been shown to vary.

In fact, according to a study published in the international pain medicine journal 'Pain Medicine,' performing radiofrequency nerve treatment on patients with chronic pain after knee artificial joint surgery resulted in observed pain reduction and potential functional improvement. However, the researchers emphasized the need for further studies to clarify the duration of the treatment's effectiveness and its indications.

Recently, in the field of artificial joint treatment, not only the success of the surgery but also postoperative pain control and patient satisfaction have established themselves as key evaluation metrics. In particular, there is a growing trend of expanding research on non-surgical treatment strategies for patients who experience persistent pain despite the absence of structural abnormalities. The medical community added that since the causes of persistent postoperative pain vary by individual, it is important to select a customized treatment plan through precise diagnosis.

Yong-gon Ko, Director of Yonsei Sarang Hospital, said, "Even if an artificial joint surgery is structurally successful, there are patients who continue to experience pain due to nerve sensitivity or chronic inflammation." He added, "Radiofrequency nerve treatment will become a non-surgical alternative that can improve the quality of life for patients suffering from postoperative pain."
