Which substances can be injected intra-articularly?
- Corticosteroids for Inflammatory Arthritis: Corticosteroid drugs play a crucial role in managing inflammatory conditions such as rheumatoid arthritis. These anti-inflammatory drugs are delivered with ultrasound guidance within the joint to reduce inflammation and provide relief from arthritis-related pain. The precision of injection placement is vital for optimal therapeutic outcome.
- Platelet-Rich Plasma (PRP) for Osteoarthritis: This technique involves a small amount of the patient's blood, which is centrifuged to separate the plasma rich in platelets. The resulting plasma is injected, guided by ultrasound, into the joint, where the growth factors of platelets lead to improved joint function.
- Hyaluronic Acid for Osteoarthritis: Hyaluronic acid is a naturally occurring substance in synovial fluid, which helps lubricate the joint and absorb shocks. Osteoarthritis reduces the amount of this substance in the patient's joint. By injecting hyaluronic acid, this deficiency is replenished, aiding joint function and reducing pain.
How important is it to perform an Intra-articular Injection with Ultrasound Guidance?
Performing an intra-articular injection without ultrasound guidance, also known as a 'blind' injection, has a lower accuracy rate compared to Ultrasound-Guided Injections. The injection of a therapeutic substance is done with precision and safety when monitoring the needle's trajectory in the joint through ultrasound. The ability to track the needle ensures both correct needle placement and precise injection of the therapeutic substance exactly where it is needed. This not only ensures the complete safety of the procedure but also guarantees the best possible therapeutic outcome.
