Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In patients with knee pain, local anesthetics and radiofrequency applications to superolateral, superomedial and inferomedial genicular nerves that innervate the knee joint are also preferred methods besides analgesic and physical therapy. When necessary, total knee replacement is the preferred method for primary knee arthrosis.

However, continuing knee pain is reported in approximately 20% of patients after total knee replacement. In similar cases; In the painful knees, the blockages of the genicular nerves are successfully applied.

In this study; the efficacy of imaging-guided radiofrequency application will be investigated in patients presenting with knee pain after total knee replacement.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Although simple analgesic and physical therapy methods are applied, some patients suffer from pain. Genicular nerve blocks and radiofrequency methods are performed usually for this reason. This procedure is performed with ultrasound and / or fluoroscopy, sterile staining and covering of painful knee to the middle of thigh and leg, localization of superomedial, superolateral, inferomedial genicular nerves are tested and then conventional radiofrequency is applied to all 3 nerve regions.Fifty patients who had total knee prosthesis for gonarthrosis in the Orthopedics and Traumatology Clinic at least 3 months postoperatively had knee pain (infection, mechanical causes and radicular pain) were included in the study.The VAS and WOMAC values recorded at the time of application and the VAS and WOMAC values recorded at the 1st week, 1st month and 3rd month after the procedure will be used to evaluate the effectiveness of the method.
