Table 6 Prevalence of meniscus abnormalities (meniscus WORMS >0 and WORMS ≥2) in the incidence and control groups by compartment

From: Texture analysis of cartilage T2 maps: individuals with risk factors for OA have higher and more heterogeneous knee cartilage MR T2 compared to normal controls - data from the osteoarthritis initiative

Prevalence of WORMS >0
  Medial Lateral
Groupa, b Anterior Body Posterior Anterior Body Posterior
Incidence group (n = 92) 1 (1.1%) 11 (12.5%) 38 (43.1%) 6 (6.8%) 4 (4.5%) 10 (11.3%)
Control group (n = 53) 0 (0.0%) 9 (20.0%) 15 (33.3%) 1 (2.2%) 0 (0.0%) 5 (11.1%)
Prevalence of WORMS ≥2

Incidence group (n = 92) 0 (0.0%) 7 (8.3%) 18 (26.4%) 3 (3.5%) 1 (1.1%) 0 (0.0%)

  1. aAll P values were greater than 0.05 using a logistic regression both when unadjusted and when adjusted for age, body mass index, and gender. bEight subjects from the control group and four subjects from the incidence group did not have whole-organ magnetic resonance imaging score (WORMS) readings available. Various subjects had lesions in multiple compartments.
