Objective: Knee genicular nerve blocks have been a topic of discussion among various types of treatment for knee osteoarthritis. This study aims to evaluate the pain and function of patients diagnosed with knee osteoarthritis after undergoing ultrasound-guided genicular nerve blockade using pharmacological agents.

Methods: The study included 36 patients diagnosed with knee osteoarthritis, comprising 17 bilateral cases, totaling 53 knees undergoing UGNB using a mixture of triamcinolone, ropivacaine, and lidocaine under ultrasound guidance. Epidemiological data, pain outcomes measured by the Visual Analog Scale (VAS), and function assessed using the Western Ontario and McMaster Universities (WOMAC) score were evaluated before and after 12 weeks of the procedure.

Results: The mean age was 75.5 years (standard deviation of 9.4 years), with a predominance of females and right-sided involvement. There was a mean reduction of 3.0 points in VAS (p < 0.001) and 15.4 points in WOMAC (p < 0.001). Two cases reported only minor and transient complications related to the procedure (skin anesthesia and edema).

Conclusion: Ultrasound-guided genicular nerve blockade using pharmacological agents demonstrated pain reduction and improved function with a low complication rate after 12 weeks in patients with knee gonarthrosis.

Rationale: Chronic knee pain is a common health issue that requires effective and noninvasive treatment. We devised a novel noninvasive approach using ultrasound-guided electrical nerve reactivation (ENR) in which ultrasound is used to identify the genicular nerve (GN). Then, transcutaneous low-frequency stimulation is applied for 10 seconds.

Total knee arthroplasty is a life-changing surgical procedure that is associated with a high incidence of severe postoperative pain. Key to enhancing recovery after surgery is effective analgesia and early mobilisation. Innovations in motor-sparing regional anaesthesia techniques that have improved recovery include targeted surgical local infiltration analgesia, adductor canal blockade, genicular nerve blocks, and the infiltration between the popliteal artery and posterior capsule of the knee (iPACK) block.

Knee osteoarthritis is a chronic degenerative disease associated with pain and decreased mobility that affects advanced-age individuals, thus causing further debilitation. Radiofrequency ablation can benefit patients who are not ideal candidates for surgical intervention and for whom conservative management has been unsatisfactory. Currently, radiofrequency ablation is performed using either ultrasonography or fluoroscopy.
