This minimally invasive procedure, helpful for patients who are looking to delay knee joint replacement surgery, or have ongoing pain after having knee joint replacement surgery.

When performing an injection, ultrasound imaging allows the radiologist to see the needle under the skin, and confirm it is in the correct location to administer the medication. This may be to alleviate pain, reduce inflammation or treat conditions such as arthritis, tendinopathy or bursitis.

The radiologist uses the ultrasound camera to visualise the needle entering into the treatment area and slowly injects a small amount of the appropriate therapeutic agent (e.g. corticosteroid for anti-inflammatory purposes, or autologous blood (ABI) for healing). The technique may also be used to withdraw excess fluid from a joint, cyst or ganglion. The interventional radiology procedure will typically take 5-10 minutes and your allocated appointment time is likely to be 15-20 minutes.
