Table 4 Sensitivity and specificity of routine magnetic resonance imaging (MRI R) and maximum knee flexion in lateral decubitus position magnetic resonance imaging (MRI S) for diagnosing partial anterior cruciate ligament tear at different stages (time from injury to examination).
| Specificity, % | Sensitivity, % | ||
|---|---|---|---|
| Subacute stage (6 weeks to 3 months) | MRI R | 79.41 | 32.43 |
| MRI S | 77.94 | 34.28 | |
| Intermediate stage (3 months to 1 year) | MRI R | 90.32 | 51.35 |
| MRI S | 90.62 | 94.44 | |
| Chronic stage (>1 year) | MRI R | 93.83 | 42..86 |
| MRI S | 96.15 | 44.68 |
