THE HIGHER BONE MINERAL DENSITY, THE LARGER OSTEOPHYTE AND THE SEVERER SYNOVITIS IN KNEE OSTEOARTHRITIS -THE BUNKYO HEALTH STUDY (BHS)

Abstract

Purpose: As prevalence of knee osteoarthritis (OA) and osteoporosis increase with aging, it has been speculated that knee OA and osteoporosis may have something in common in the pathophysiology. However, it is still controversial whether there is any association between bone mineral density (BMD) and knee OA.While prevalence of any MRI-detected OA-related structural changes was approximately 90% among middle-aged populations without radiographic knee OA (Kellgren-Lawrence [K/L] 0), osteophyte is the most common abnormality among all participants (about 75%), followed by cartilage damage (about 70%) (BMJ 2012).
