Genicular Nerve Block (G Block)

If chronic knee pain from osteoarthritis or previous joint surgery is limiting your mobility, sensitive sensory nerves may be transmitting constant pain signals to your brain. A Genicular Nerve Block (G Block) is a targeted diagnostic and therapeutic procedure designed to temporarily “turn off” the principal nerves supplying the knee joint. Guided by real-time ultrasound or fluoroscopy, a precise dose of local anesthetic is injected around the genicular nerves. This procedure provides rapid pain relief, confirms if these nerves are your primary pain generators, and determines your candidacy for longer-lasting treatments like Radiofrequency Ablation.
