Natural History of Intrameniscal Signal Intensity on Knee MR Images: Six Years of Data from the Osteoarthritis Initiative.

ABSTRACT:

Purpose

To assess the natural history of intrameniscal signal intensity on magnetic resonance (MR) images of the medial compartment.

Materials and methods

Both knees of 269 participants (55% women, aged 45-55 years) in the Osteoarthritis Initiative without radiographic knee osteoarthritis (OA) and without medial meniscal tear at baseline were studied. One radiologist assessed 3-T MR images from baseline and 24-, 48-, and 72-month follow-up for intrameniscal signal intensity and tears. A complementary log-log model with random effect was used to evaluate the risk of medial meniscal tear, adjusting for age, sex, body mass index, and knee side.

Results

At baseline, linear intrameniscal signal intensity in the medial compartment was present in 140 knees (26%). Once presen
