Knee pain blocks (also known as knee blocks) refer to a type of nerve block or local anaesthetic injection used to manage and alleviate knee pain, particularly when the pain is chronic, severe, or not responding well to other forms of treatment. These blocks work by numbing or blocking the nerve signals that carry pain sensations from the knee to the brain.

Knee pain can arise from a variety of conditions such as osteoarthritis, injury, ligament tears, patellofemoral pain syndrome, or cartilage damage. A knee pain block is typically used as part of a comprehensive treatment plan to help manage pain and improve the patient's quality of life.
