More Weight Loss Is Better for Knee OA

When it comes to easing the symptoms of knee osteoarthritis (OA), the more weight loss, the better, according to researchers at Wake Forest University in Winston-Salem, North Carolina. In a study published recently online in Arthritis Care & Research, Stephen Messier, PhD, and colleagues report that overweight and obese adults aged 55 and older with knee OA who lost 20 percent or more of their body weight saw far greater improvements in pain, function, quality of life, inflammation and knee joint stress than those who lost less.

In an earlier trial, the same researchers found that a weight loss of 10 percent – the amount the National Institutes of Health recommends for overweight and obese adults – improved mobility and decreased pain by 50 percent over an 18-month period. In their latest findings, they say doubling weight loss can cut pain and improve function by another 25 percent.

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.
