PRS treatment + Genicular nerve block for knee arthritis in India. See how PRS treatment is combined with a genicular nerve block to relieve the pain of knee arthritis. The genicular nerves carry pain sensations from the knees to the brain. They can be blocked temporarily with local anaesthesia as in this case or prolongedly with alcohol and radiofrequency ablation. The later radiofrequency ablation of genicular nerves will be used to treat painful total knee replacements by me in future.
