Diagnostic accuracy of clinical examination and MRI in intra-articular knee disorders (adapted from Kocher et al 27)
| Diagnosis | Sensitivity (%) | Specificity (%) | Positive predictive value (%) | Negative predictive value (%) | ||||||
| Clinical examination | MRI | P value | Clinical examination | MRI | P value | Clinical examination | MRI | Clinical examination | MRI | |
| ACL tear | 81.3 | 75.0 | 0.55 | 90.6 | 94.1 | 0.39 | 49.0 | 58.6 | 97.8 | 97.1 |
| Medial meniscus tear | 62.1 | 79.3 | 0.15 | 80.7 | 92.0 | 0.03 | 14.5 | 34.3 | 97.6 | 98.8 |
| Lateral meniscus tear | 50.0 | 66.7 | 0.24 | 89.2 | 82.8 | 0.21 | 34.0 | 30.1 | 94.1 | 95.7 |
Clinical examination was patient history, physical examination and X-rays performed by a paediatric orthopaedic sports medicine specialist or a postresidency paediatric sports medicine fellow.
