Table 4 Associations between medial meniscal extrusion at baseline and change in cartilage volume over 2 years

From: Knee meniscal extrusion in a largely non-osteoarthritic cohort: association with greater loss of cartilage volume

Factor Univariable β (95% CI) Multivariablea β (95% CI) Multivariableb β (95% CI)
Medial tibial (%) -2.29 (-0.41 to -0.45)* -1.26 (-2.95 to +0.43) -1.01 (-2.88 to +0.86)
Medial femoral (%) -0.73 (-2.06 to +0.59) -0.87 (-2.23 to +0.49) -1.56 (-2.99 to -0.14)*
Medial tibiofemoral (%) -1.42 (-2.66 to -0.17)* -1.18 (-2.41 to +0.05) -1.44 (-2.76 to -0.12)*
Lateral tibial (%) -0.14 (-1.69 to +1.41) +0.43 (-1.09 to +1.94) +0.64 (-0.94 to +2.23)
Lateral femoral (%) -0.28 (-1.54 to +0.98) -0.34 (-1.62 to +0.94) -0.27 (-1.61 to +1.07)
Lateral tibiofemoral (%) -0.28 (-1.45 to +0.88) -0.07 (-1.22 to +1.09) +0.15 (-1.05 to +1.35)
  1. The dependent variable was change in cartilage volume. aAdjusted for age, sex, offspring-control status, body mass index, past knee injury and baseline cartilage volume. bFurther adjusted for baseline tibial bone area and osteophytes. *Statistically significant associations. CI, confidence interval.
