Knee OA

Knee OA

The Annals of Internal Medicine reported this month that Americans over 50 with knee osteoarthritis lose about 86 million “quality-adjusted life-years”.  A computer simulation called the “Osteoarthritis Policy Model” examined the effects of knee OA and obesity.  The simulation compared adults between the ages of 50 to 84 and divided them into four groups:  obese patients, patients with Knee OA, obese patients with knee OA, and people without knee OA who aren’t obese.

Obese patients with knee OA lose twice as many “quality-adjusted life-years” compared to the group that wasn’t obese and didn’t have knee OA.  The groups that faired the worst were black and hispanic women.  The authors of the publication wrote, “the disproportionate burden these conditions impose on black and hispanic women suggests that future studies should investigate tailoring prevention and treatment strategies to sex and racial or ethnic subpopulations.”
