Relation of tear type to meniscal position of the lateral meniscus at baseline adjusted for osteoarthritis and body mass index effects.
| Lateral extrusion (mm), Coefficient (SE) | Anterior extrusion (mm), Coefficient (SE) | Proportion of coveragea, % Coefficient (SE) | |
|---|---|---|---|
| Horizontal tear (n = 1) | 0.18 (0.06)* | 0.28 (0.06) | −8.06 (3.69)* |
| Vertical tear (n = 2) | −0.06 (0.08) | −0.07 (0.09) | 0.82 (5.20) |
| Maceration (n = 1) | −0.02 (0.11) | 0.11 (0.12) | −8.06 (7.22) |
| Signal (n = 14) | −0.002 (0.02) | −0.001 (0.03) | 3.27 (1.57)* |
| Mean value in normal menisci (n = 131) | 0.19 | 0.04 | 19.35 |
| Complex tearb (n = 1) | |||
| Meniscal cystb | 0.30 | 0.60 | 25.0 |

Indicates significance α = 0.05
a
Proportion of coverage = meniscal covering/meniscal covering + meniscal uncovering.
b
Meniscal abnormalities occurring in a single subject not included in the model to prevent bias.
