Genicular Nerve Block
Personalized interventional pain care
Genicular Nerve Block is one treatment option that may be considered when pain, inflammation, or nerve signaling continues to interfere with movement, sleep, work, or daily routines.
At first, it may only appear during certain activities. Climbing stairs becomes uncomfortable. Standing for long periods feels harder than it used to. Walking through the grocery store or getting out of a car may trigger aching pain deep inside the knee.
Over time, many patients begin adjusting their entire routine around avoiding discomfort.
The purpose of Genicular Nerve Block is not to promise a cure. It is to address a carefully identified pain source, support function, and help the patient participate more comfortably in an individualized care plan.
What Is Genicular Nerve Block?
Understanding the diagnosis and treatment target helps set realistic expectations before Genicular Nerve Block is recommended.
The knee is one of the most heavily used joints in the body.
Because the knee handles so much weight and movement, it is vulnerable to wear, injury, inflammation, and degeneration over time.
When chronic inflammation or joint damage develops, pain signals travel through small nerves surrounding the knee called the genicular nerves.
A genicular nerve block is a minimally invasive procedure used to temporarily interrupt pain signals coming from the knee joint.
During the procedure, medication is injected near the genicular nerves surrounding the knee.
The purpose is to reduce pain signaling and determine whether the genicular nerves are major contributors to the patient’s knee pain.
When Genicular Nerve Block May Be Considered
A procedure or medication plan is chosen only after the likely pain source, prior care, health history, and personal goals have been reviewed.
Chronic Knee Pain After Surgery
Some patients continue experiencing pain even after knee replacement or surgical procedures. Common considerations include Some patients continue experiencing pain even after knee replacement or surgical procedures.

Symptoms and Daily-Life Effects to Discuss
Tell your clinician where symptoms occur, what makes them better or worse, and how they affect function. That pattern can be as important as an imaging result.
- Deep aching pain
- Sharp pain during movement
- Stiffness after sitting
- Pain climbing stairs
- Difficulty standing from seated positions
- Swelling and reduced mobility
- Pain may gradually worsen over time and begin interfering with everyday independence

Step 1: Preparation
The patient is positioned comfortably, and the knee area is cleaned carefully. Common considerations include The patient is positioned comfortably, and the knee area is cleaned carefully, Local anesthesia may be used to numb the skin.
Step 2: Imaging Guidance
Using fluoroscopy or ultrasound guidance, the physician carefully identifies the targeted genicular nerves surrounding the knee. Common considerations include Imaging guidance improves precision and safety.
Step 3: Medication Injection
Medication is delivered near the genicular nerves to temporarily interrupt pain signaling. Common considerations include Medication is delivered near the genicular nerves to temporarily interrupt pain signaling.
