| Procedure / test | Category | What it is |
|---|---|---|
| Joint aspiration (arthrocentesis) | Bones, Joints & Spine | Joint aspiration removes fluid from a swollen joint with a needle for testing and to relieve pressure. The fluid is examined for crystals (gout, pseudogout), infection (septic arthritis) and inflammation — one of the highest-yield tests in joint medicine. |
| Joint injection (corticosteroid / hyaluronic acid) | Minor Procedures & Pain | A joint injection places medicine directly into a joint space: corticosteroid to dampen inflammation (for arthritis flare or bursitis), or hyaluronic acid (a joint-lubricant preparation) mainly for knee osteoarthritis. Injections are often ultrasound-guided to confirm placement. |
| Joint injection (steroid) | Bones, Joints & Spine | A joint injection delivers corticosteroid (and usually local anaesthetic) directly into a painful joint to reduce inflammation and pain. Ultrasound or X-ray guidance is used for deeper joints such as the hip. |
Please note: This page is educational information about a medical procedure or test. It does not replace the instructions of your own care team, who know your situation and whose preparation, fasting and medication advice you should follow if it differs from anything here. If you have symptoms that worry you, or an appointment you do not understand, contact your clinical team.
