Chondroitin sulfate improves osteoarthritis (OA) knee pain and functional limitations in walking and daily activities as effectively as the anti-inflammatory drug celecoxib (Celebrex), according to a new study published recently in Annals of the Rheumatic Diseases. But U.S. readers should know, there’s a catch: the researchers tested a version of chondroitin sulfate that is not available in this country.
About 40 percent of adults in the United States are likely to develop osteoarthritis (OA) in at least one hand by age 85, and some people are more at risk than others, according to researchers at the Centers for Disease Control and Prevention (CDC). Their findings were published recently in the journal Arthritis & Rheumatology.

Losing excess weight may help preserve knee cartilage in people who have or are at risk of knee osteoarthritis (OA), according to researchers at the University of California, San Francisco (UCSF), whose findings were recently published online in the journal Radiology. Knee cartilage is the rubbery, slick cap that covers the ends of the upper (femur) and lower (tibia) leg bones that make up the knee joint.
Their study also found that shedding extra pounds protected the menisci, the crescent-shaped cartilage pads that cushion the knee joint. Lead author Alexandra Gersing, MD, a postdoctoral scholar at UCSF School of Medicine, says this is especially important because a torn or damaged meniscus can speed up the degeneration of the knee joint overall.

A diet high in fat, especially saturated fat, may speed up the progression of knee osteoarthritis (OA), whereas eating greater amounts unsaturated fat might slow it down, according to researchers at Brigham and Women’s Hospital in Boston. Their study, published recently in Arthritis Care & Research, is one of the first to look at the effect of diet on the rate of OA progression. The researchers say they undertook the study because diet plays a role in the development of many chronic diseases, including diabetes, cancer and cardiovascular disease, and they suspected it might also be involved in osteoarthritis.

Just 45 minutes a week of moderate to vigorous exercise may help improve or maintain a high level of function for people with osteoarthritis (OA), according to study published online recently in Arthritis Care & Research.

Overloaded or unevenly loaded knee joints can cause osteoarthritis (OA), or cause your OA to get worse. Learning how to walk differently may be able to correct the loading problem and reduce your knee pain. This approach is being studied in people with medial, or inner, compartment OA — which is 10 times more common than other forms of knee OA.

A relatively new treatment for knee osteoarthritis (OA) appears to reduce pain better than traditional corticosteroid injections, according to a study published recently in International Journal of Rheumatic Diseases.

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.
