Weight Still Top Risk Factor for Knee Arthritis, Pain

Other factors include female gender, previous knee injury, age, and presence of hand OA.

Familiar risk factors for knee osteoarthritis (OA) in individuals 50 years and older — high body mass index (BMI), previous knee injury, age, female sex, and the presence of hand OA — were confirmed as the condition’s top drivers in a new systematic review and meta-analysis with an updated evidence base.

One-fourth of cases of onset of knee pain could be attributable to being either overweight or obese, according to Victoria Silverwood and colleagues at the Arthritis Research UK Primary Care Centre at Keele University in Staffordshire, England.

The finding emphasizes “the continued importance of weight loss as a management option for OA,” they wrote in Osteoarthritis and Cartilage. “Our calculated PAF [population attributable fraction] values demonstrate that 24.6% of cases of onset of knee pain could be attributed to being either overweight or obese.”

Data from 46 published studies up to December 2012 were extracted for the systematic review to assess the association between potential risk factors and knee pain/knee OA in study cohorts with a mean age of 50 years and older. Thirty-four studies in which risk factors had consistent definitions across studies were included in the meta-analysis.
