What is a Genicular Nerve Block (G Block)?
A Genicular Nerve Block (G Block) is a minimally invasive procedure used to diagnose and manage chronic knee pain. This treatment involves injecting a local anesthetic near the genicular nerves, which transmit pain signals from the knee joint to the brain. By blocking these nerves, the procedure provides temporary pain relief and helps determine if further treatments, such as Genicular Nerve Ablation, are appropriate.
Conditions Treated
- Chronic knee pain
- Osteoarthritis of the knee
- Persistent pain after knee surgery
- Pain from knee injuries
How Does the Procedure Work?
Using fluoroscopic (X-ray) or ultrasound guidance, the physician inserts a thin needle near the targeted genicular nerves around the knee. A local anesthetic is injected to block the pain signals, providing temporary relief.
What to Expect
- Pre-Procedure Preparation: Patients may need to stop certain medications and avoid eating or drinking a few hours before the procedure.
- Procedure: The patient lies on their back, and the targeted area is cleaned and numbed. The physician uses imaging guidance to precisely place the needle and administer the anesthetic.
- Post-Procedure Care: Patients may experience immediate pain relief that lasts for several hours or days, helping determine if further nerve treatments are necessary.
