Is it Possible to Delay or Avoid Knee Replacement Surgery?

Chronic knee pain is often caused by osteoarthritis or degenerative joint diseases. This condition not only negatively impacts patients' mobility and sleep quality but also brings about additional issues, such as irritability, fatigue, and even depression. There are many ways to combat chronic knee pain—exercise, braces, pain-relieving medications—but sometimes these methods can be ineffective. In such cases, a genicular nerve block is recommended for patients.

What is a Genicular Nerve Block?

A genicular nerve block is a procedure that blocks a group of nerves responsible for transmitting pain signals to the brain. This is done by injecting an anesthetic near the nerve endings in the knee area. The procedure takes no more than 30 minutes, and the pain relief effect is felt immediately or within a few days. It is essential to understand that a genicular nerve block does not cure chronic knee pain—it only alleviates the sensation of pain.

When Should a Genicular Nerve Block Be Performed?

This procedure is advisable when other pain management methods have been ineffective. A genicular nerve block is also recommended in cases of sudden flare-ups in knee pain.

A preliminary consultation with a pain specialist is required before any procedure. The Pain doctor will always address any questions and provide the most appropriate treatment plan.

Is This Procedure Painful?

A genicular nerve block is a painless procedure. Only the anesthetic injection process may cause slight discomfort. In exceptional cases, for instance, due to high anxiety, intravenous sedation may be administered before the procedure.

What Are the Side Effects of a Genicular Nerve Block?

This is a non-surgical procedure, so the risk of side effects is very low. Rarely, patients may experience pain, swelling, or redness at the injection site, as well as leg numbness, nausea, and dizziness.

How is the Genicular Nerve Block Procedure Performed?

• The patient is either seated or lying on their back;
• If necessary, intravenous sedation is applied;
• The knee area is cleaned and disinfected;
• Using ultrasound or fluoroscopy, the genicular nerves are located;
• A thin needle is used to numb the skin over the knee locally. Once effective, a larger needle is used to inject anesthetic near the nerve endings;
• The needle is withdrawn, and a bandage is applied to the injection site.

Post-Procedure Recommendations

• If intravenous sedation was applied, it is advised not to drive home;
• Avoid intense physical activity for 24 hours post-procedure;
• In cases of nausea or dizziness, drink water and have a light snack. If symptoms persist, consult a doctor;
• In case of swelling at the injection site, apply ice.
