These type of injections involves a gel-like substance designed to support joint function. When administered into the joint by a health care professional, it can help to:
Improve lubrication and shock absorption
Reduce inflammation within the joint
Provide pain relief
Support the production of healthier joint fluid
Protect remaining cartilage
These injections may be used in joints such as the knee, hip, ankle, foot, shoulder, elbow, wrist, and base of the thumb.
The Treatment
This therapy is often more effective when the joint is less swollen or inflamed. For this reason, any excess fluid may be aspirated and sometimes treated with cortisone several weeks before starting.
Injections are performed under CT guidance and sterile conditions by a doctor
Treatment usually involves a series of three injections, spaced about two weeks apart. Each appointment takes approximately 10–15 minutes, and patients are generally able to drive afterward
At the first appointment, any excess joint fluid may be removed using the same needle before the injection is given
A short period of relative rest (around 48 hours) is recommended after each injection, avoiding activities that aggravate symptoms
Benefits are typically most noticeable after 6–8 weeks, with relief sometimes lasting more than 6 months. Treatment can usually be repeated up to twice a year if needed
Side Effects and Risks
Temporary joint swelling or stiffness
Mild pain or bruising at the injection site
Rarely, infection. If fever, increasing pain, swelling, redness or warmth occur in the week following an injection, contact your doctor immediately
