Meniscal Ramp Injury Diagnosis.

Objective : This study compared diagnostic methods for meniscal ramp injury (magnetic resonance imaging [MRI], arthrotomography, and arthroscopy) to determine the most sensitive and the agreement level between them. Method:  We studied 21 patients, all young athletes with suspected anterior cruciate ligament (ACL) injury after trauma for at least 3 months and no evidence or history of other osteoarticular injuries in the knee. The patients underwent MRI and arthrotomography. Following ACL injury confirmation, they underwent arthroscopy for ligament reconstruction and evaluation of the medial meniscus to confirm or exclude a ramp injury. McNemar's agreement test compared the diagnostic methods. We also assessed specificity and sensitivity using arthroscopy as the gold standard with a 95% confidence interval and p < 0.005. Result : The results were consistent with the literature. MRI had 73.3% sensitivity and 83.3% specificity, with 76.2% agreement with the gold standard. Arthrotomography sensitivity and specificity were 100% and 66.7%, respectively, with 90.5% agreement with arthroscopy. Conclusion : In our study, arthrotomography was the most sensitive diagnostic method and had the highest agreement with the gold standard. We recommend its consideration for diagnosing ACL injuries.
