Knee OA More Common Now Than at Any Time in the Last 6,000 Years

A team of researchers from the United States and Finland has found that rates of knee osteoarthritis (OA) are higher now than in the past – probably not for the reasons you think.

In a study published in the Proceedings of the National Academy of Sciences, the researchers report that knee OA is more than twice as common today, in the post-industrial era, as it was at any time before, going back to prehistoric days. People in the 21st century are also more likely to have arthritis in both knees than were people in the past.

A New Study Finds Pharmaceutical Chondroitin Helps Knee OA Pain and Function

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.

Hand OA Risk Higher for Women, Caucasians, Overweight People

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.

Study Confirms That Losing Weight May Save Your Knees

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.

Healthy Fats and OA

A Diet of Bad Fats May Hasten Knee OA Progression

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.

Osteoarthritis Knee Pain Walking

Change the Way You Walk to Ease Knee Pain with Osteoarthritis

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.
