Mobility and Muscular Power of Lower Limbs in Elderlies with Radiographic Moderate Knee Osteoarthritis (OA) but No Knee Pain was Inferior to That of Those in Elderlies with Radiographic Primary Knee Osteoarthritis (OA) but No Knee Pain - A Population-Based Cohort Study “Sportology Core Study 2”

Purpose: Pain is the major reason why individuals seek medical attention from early-through endstage knee OA, and is also a major determinant for the loss of joint function. The prevalence of knee osteoarthritis (OA) in women in eighties is reported to be >80% regardless of the presence or absence of knee pain. There are a plenty of elderlies who don’t have knee pain but show the several different stages of radiographic knee OA. However, it is unclear whether the mobility and muscular power of the lower limbs in subjects who show the advanced-stage knee OA but do NOT have knee pain is different from that of those in subjects who show the early-stage knee OA but do NOT have knee pain.
