Pain management in patients with knee osteoarthritis by ultrasound-guided genicular nerve block. Case reports
ABSTRACT BACKGROUND AND OBJECTIVES: Knee osteoarthritis is a chronic disease that tends to affect elderly people and is characterized by severe pain, joint stiffness and limited function. In more advanced cases, the initial approach of knee osteoarthritis performed with traditional conservative pharmacological or non-pharmacological treatment may not present satisfactory results. There are alternatives for pain intervention with favorable results, with longer analgesia and that can help rehabilitation, such as analgesic peripheral nerve blocks, including the genicular nerve block, and radiofrequency ablation. The objective of this study is to report cases of genicular nerve block guided by ultrasonography, with favorable results in relation to analgesia and return of functional capacity. CASE REPORTS: Four elderly patients diagnosed with advanced knee osteoarthritis, with limited range of motion, and with severe chronic pain (mean visual numeric scale - VNS=7.75) were submitted to ultrasound-guided genicular nerve block, presenting significant pain improvement (mean VNS after 1 month of block=2.25) and regain of functional capacity. There were no cases of complications. CONCLUSION: Genicular nerve block guided by ultrasonography is a technique that can be performed as an intervention measure in pain. It presents satisfactory results of analgesia and regain of functional capacity, facilitating the rehabilitation process, and can be adopted in an outpatient clinic context.
