Relation of tear type to meniscal position of the medial meniscus at baseline adjusted for osteoarthritis and body mass index effects.
| Medial extrusion (mm), Coefficient (SE) | Anterior extrusion (mm), Coefficient (SE) | Proportion of coveragea, % Coefficient (SE) | |
|---|---|---|---|
| Horizontal tear (n = 5) | 0.008 (0.04) | 0.02 (0.05) | 0.43 (2.25) |
| Vertical tear (n = 1) | −0.04 (0.09 | 0.10 (0.12) | 2.46 (5.27) |
| Complex tear (n = 1) | 0.27 (0.07)* | 0.23 (0.10)* | −4.95 (4.49) |
| Meniscal cyst (n = 4) | 0.14 (0.06)* | 0.16 (0.09) | −0.78 (3.72) |
| Maceration (n = 11) | 0.21 (0.04)* | 0.22 (0.05)* | −7.63 (2.19)* |
| Signal (n = 26) | 0.02 (0.02) | 0.03 (0.04) | 1.27 (1.20) |
| Mean value in normal menisci (n = 68) | 0.360 | 0.453 | 13.90 |
