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.

A new study takes a look at which approaches are best to bring relief to people with knee osteoarthritis (OA), a condition that affects approximately 20 percent of people over the age of 45 in the United States.
Knee OA can be extremely painful and limit a person’s ability to function. Although there is no cure, numerous treatments are available to reduce symptoms, including over-the-counter and prescription drugs. Exercising and losing weight if a patient is overweight or obese also can help. Total knee replacement surgery is effective but is done only in cases where the disease is advanced and it’s medically necessary.
So, which treatment is best? To help sort out the choices, a group of researchers set out to assess how the available non-surgical drug treatments stack up against each other for providing pain relief and improving physical function. The authors did not address lifestyle changes, like weight loss and exercise. The study was published recently in Journal of American Academy of Orthopaedic Surgeons (JAAOS).

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.
