Prevalence of abnormal findings in 230 knees of asymptomatic adults using 3.0 T MRI
- 97% of asymptomatic adults showed abnormalities in at least one knee structure.
BACKGROUND & OBJECTIVE
Magnetic resonance imaging (MRI) is frequently used to detect changes in joints, and the sensitivity of the detection depends on the type of MRI. 1.5 Tesla (T) MRI is widely used but has limitations in evaluating abnormalities of the hyaline articular cartilage and meniscus. 3.0 T MRI allows improved visualization of these structures. The purpose of this study was to use 3.0 T MRI to determine the prevalence of abnormal knee findings in asymptomatic sedentary adults.
Decisions to undergo surgery should not place excess reliance on MRI results.
115 adults participated in the study. They were all asymptomatic, which was determined by assessment of a Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire. The participants were all sedentary, meaning they did not meet existing physical activity recommendations (30
