If you have osteoarthritis (OA), you know all about joint pain and stiffness. One cause of these symptoms is the fact that hyaluronic acid (HA), a naturally occurring joint lubricant, breaks down in people with OA. To help alleviate the pain, your doctor might recommend treatment with hyaluronic acid injections – sometimes known as gel injections.
What are HA injections?
HA injections replace missing joint lubricant and are currently approved by the Food and Drug Administration (FDA) for use in the knees. However, some doctors may use the injections in shoulders and hips as well.
The treatments will most likely take place in your doctor’s office. The HA will be injected directly into the joint. The shots are usually given once a week for three to five weeks, depending on the brand used.

For some people with knee osteoarthritis (OA), hyaluronic acid (HA) injections can relieve pain and improve function – sometimes dramatically. During the procedure, hyaluronic acid– a substance similar to the naturally occurring gel-like lubricant that is found in the synovial fluid surrounding joints – is injected into the knee. Because people with OA have a lower than normal concentration of hyaluronic acid in their joints, the theory is that adding the lubricant to the arthritic joint will reduce pain and help with movement.
But HA injections, also called viscosupplements, don’t work for everyone: Studies have shown that between 30 and 40 percent of patients who are given HA shots for knee OA don’t experience a reduction in pain or an improvement in function. And studies have not provided any insight into which patients are most or least likely to benefit from them.
