A joint injection is a procedure used to treat conditions such as rheumatoid arthritis, psoriatic arthritis, gout, tendinitis, and bursitis.
How is the procedure performed?
You will be given a local anesthesia by your physician. A needle will be inserted into the target joint, and anti-inflammatory agents or Hyaluronic acid, a lubricating substance, are delivered through the needle. The joints that are commonly treated using this procedure are knee, shoulder, ankle, elbow, wrist, thumb, and small joints of the hands and feet. Hip joint can also be treated under the guidance of X-ray.
Possible side effects and risks
Some of the side effects and risks include allergic reactions to the injected medicines. Very rarely, in 1 out of 15,000 corticosteroid injections, infections may result. Post-injection flare, which is defined by the swelling of joint and pain, may arise in 1 out of 50 patients. Other complications may include local fat atrophy at the injection site, depigmentation of the skin, and rupture of a tendon.
Who should not get the treatment?
If you have an active infection around a joint and if you are allergic to any of the medications that are injected, you should not get the treatment until the problems resolve.
