Comparison between radiologists’ and orthopaedic surgeons’ findings in MRI-based diagnosis.
| Orthopaedic surgeons | Radiologists’ accuracy | Orthopaedic surgeons’ accuracy | CMH test (p-value) |
|---|---|---|---|
| Osteochondral lesions | |||
| Medial condyle | 0.623 | 0.592 | 0.130 |
| Medial plateau | 0.568 | 0.474 | 0.620 |
| Lateral condyle | 0.638 | 0.638 | 0.276 |
| Lateral plateau | 0.659 | 0.420 | 0.681 |
| Patello femoral | – | – | – |
| Ligamentary lesions | |||
| ACL (yes/no) | 0.743 | 0.695 | <0.001 |
| Meniscal lesions | |||
| Medial (yes/no) | 0.753 | 0.742 | 0.089 |
| Lateral (yes/no) | 0.604 | 0.680 | 0.084 |
| Synovitis | 0.567 | – | – |
CHM test, Cochran–Mantel–Haenszel test; ACL, anterior cruciate ligament.
Although menisci readings were nearly the same between radiologists and orthopaedic surgeons, only ACL injuries achieved statistically significant association (p < 0.001); patellofemoral lesions have no data as accuracy could not be calculated; orthopaedic surgeons’ synovitis accuracy could not be calculated, hence the absence of a p-value in the Cochran–Mantel–Haenszel test.
