An infrapatellar saphenous nerve block is a procedure designed to diagnose and relieve knee pain, particularly after injuries or surgeries like ACL repairs or meniscus operations. This sensory nerve sends pain signals from the skin below the kneecap and the front knee joint.

When irritated or injured, it can cause chronic pain. During knee surgeries, this nerve may suffer damage, leading to mild sensory changes or neuropathic pain, requiring treatments like nerve blocks, medications, or more advanced options in severe cases.

The procedure involves injecting a local anesthetic, possibly with an anti-inflammatory steroid, near the nerve. This injection blocks pain signals to the brain, providing relief. The technique uses a needle guided by ultrasound for accuracy and safety, with minimal risks such as infection, bleeding, or temporary numbness.

Relief is usually immediate, lasting several hours to weeks, depending on treatment goals. If pain recurs, treatments like repeat nerve blocks, cryoneuroablation, or radiofrequency ablation may offer longer-lasting relief. Continuing physical therapy can aid in recovery and restore knee function.

Overall, the goal is to diagnose and manage knee pain non-surgically, allowing you to return to daily activities more comfortably.
