Do Injections Help Osteoarthritis in the Knees?
Since osteoarthritis (OA) commonly affects the knees, which are a vital part of your general mobility, there are a plethora of options aimed at easing pain and restoring function. Every one of them varies in its degree of effectiveness, cost, and availability. Anyone with OA has probably heard of the various injections designed for the knee, but most know little beyond the fact that they exist.
How Knee Injections Work
Knee injections are often considered when less invasive options like NSAIDs have not worked well for a particular patient. After a local anesthetic is administered, a doctor will insert the needle below the kneecap, injecting a solution that spreads through the joint area. The two most common injections are corticosteroids and hyaluronic acid, each of which carries different side effects and benefits.
Corticosteroid Injections
Corticosteroid injections are used to address the swelling and buildup of fluid in the knee that is caused by inflammation. Although they work quickly, the effect rarely lasts more than 6-12 weeks. They also tend to lose effectiveness after each consecutive shot. Doctors typically recommend that an individual not exceed 2-3 shots per year. This type of injection is better suited to “flare-ups” and acute pain.
Hyaluronic Acid Injections
Most of the fluid in a healthy knee is made up of hyaluronic acid. A knee affected by OA has significantly less of this fluid, which contributes to increased pain. The addition of hyaluronic acid helps cushion and lubricate the joint. This approach is often used as a second resort, as the injections are fairly expensive and require several administrations. Some patients feel the benefits of hyaluronic acid injections are short lived in relation to their cost.
Should You Consider Knee Injections for OA Pain?
Before considering invasive treatments and injections, many doctors suggest starting with less invasive approaches and natural options. People who live with OA pain in the knee often do best with a comprehensive approach to their arthritis. Addressing your diet, lifestyle, and exercise, and adding natural options like supplementation, can help support everyday joint comfort along with your overall health. Individual results vary, so talk with your doctor about what makes sense for you.
