A joint injection is an outpatient procedure that is used to treat inflamed joints. The injection can be used to treat conditions like rheumatoid arthritis, psoriatic arthritis, gout, tendinitis, bursitis, carpal tunnel syndrome, and osteoarthritis. During the procedure, the patient will lie on the procedure table while an assistant sterilizes that area where the injection will be. The area will then be numbed with a local anesthesia or cold spray. The physician will most likely use an x-ray to help direct a small needle into the joint. Lastly, the physician will inject the medication into the joint. After the procedure is over the patient will rest before being released to a family member or friend. Depending on the medication, the injection can provide relief from pain, swelling, and stiffness. The following are common join injections we perform here at our facilities:
- Facet Joint Injection
- Knee Injection
- Hip Joint Injection/Ablation
- Shoulder Injection
- SI Joint Injection
Viscosupplementation Treatment For Knee Arthritis
During viscosupplementation treatment for arthritis, our provider injects hyaluronic acid into your joint. This thick fluid may help reduce pain and swelling in your arthritic joint (most commonly, your knee).
The bones that make up your joints usually have a cap of cartilage on their ends. This cartilage helps make sure that your bones move smoothly against each other. This cartilage has a fluid coating that contains hyaluronic acid. This works like a lubricant and shock absorber in your joint.
In osteoarthritis (“wear-and-tear” arthritis), this cartilage cap breaks down. When this happens, the bones of your joint scrape together abnormally. People with osteoarthritis generally have less hyaluronic acid in their joints than they should. All of this causes symptoms like pain, stiffness, and swelling. The idea behind viscosupplementation is that replacing this hyaluronic acid may help reduce symptoms.
Our doctor may first inject a numbing medicine into the space around your knee joint and possibly drain any fluid that is causing the joint to swell. Then, our surgeon will inject hyaluronic acid into the space inside your joint. You shouldn’t expect this to reduce your pain right away. After the full course of treatment, though, you may notice some pain relief.
