The Effect of Therapeutic Methods for Chronic Knee Osteoarthritis Pain

Status Completed

Clinical Trial Summary

Chronic osteoarthritis (OA) pain of the knee is not effectively abrogated by the available non-pharmacologic or pharmacologic treatments. Radiofrequency (RF) neurotomy is a therapeutic alternative for chronic pain. Here, the researchers investigate the efficacy of RF neurotomy applied to articular branches (genicular nerves) in treating knee joint pain.

Clinical Trial Description

The knee joint is innervated by articular branches of various nerves (femoral, common peroneal, saphenous, tibial and obturator) (Kennedy et al. 1982; Hirasawa et al. 2000). These articular branches around the knee joint are known as genicular nerves. Several genicular nerves can be easily approached percutaneously under fluoroscopic guidance. In our study, genicular nerves were effectively blocked with local anesthetics under fluoroscopic guidance, leading to a significant reduction in knee pain. Rf neurotomy is based on the theory that cutting the nerve supply to a painful structure may alleviate pain and restore function. we evaluate the efficacy of RF neurotomy in reducing pain and improving function in the elderly with chronic knee OA. ;
