Cortisone
Cortisone, which is injected directly into joints, may be used to help relieve both swelling and pain. Cortisone is a naturally occurring hormone produced by the adrenal gland. It helps regulate inflammation and when injected into a joint can relieve or reduce both swelling and pain. Relief usually occurs within a day or two of the injection. Patients do not need to change activities following injections. Many patients elect to receive cortisone injections prior to big events when they will be more active. Occasionally, a patient may experience a “flare,” which may increase pain for a few days.

Cortisone may play a role in weakening tendons or cartilage if used too often. Therefore, most physicians limit its use to a few times per year depending on the circumstances.

Always consult your physician before participating in any treatment option.

Hyaluronates
Hyaluronate injections have been approved for arthritis of the knee. They may help relieve osteoarthritis pain and restore joint function. Hyaluronate is a naturally occurring substance in joint fluid that provides lubrication and cushioning to the joint. As osteoarthritis continues to develop, the joint fluid becomes thinner, with less hyaluronate and thus loses its ability to properly lubricate and cushion the joint cartilage.

Several synthetic forms of hyaluronate have been developed to use in the knee joint. In order to be effective, anywhere from three to five injections must be given weekly. The effectiveness is usually not noted for at least a month. Patients do not need to significantly reduce activity following injection. Various studies have indicated maximum effectiveness at anywhere between 50–70%. Studies have shown that the more severe the arthritis, the less effective the injections. However, when effective, the relief may last for 6–12 months. Synthetic hyaluronate is made from rooster combs. Therefore, anyone who is allergic to feathers, chickens or egg products should not receive an injection.
