Abstract:
Objective To investigate clinical value of MRI and arthroscope in diagnosis of anterior cruciate ligament, and to compare diagnosis accuracy and provide a reference for clinical diagnosis. Methods A total of 40 suspected pa-tients with anterior cruciate ligament were selected from July 2011 to July 2014, MRI were used in all patients before surgeries for diagnosing, and arthroscope was used during surgeries, results were compared between MRI and arthro-scope application. Results 10 cases of 44 suspected ACL knees were detected normal under arthroscope, the other 34 cases were detected injured, partial tear 11 cases while complete tear 23 cases;Under MRI 11 cases were detected nor-mal, the other 33 cases were detected injured, partial tear 13 cases while complete tear 20 cases. The sensitivity of MRI was 91.18%(31/34), the specificity rate was 72.73%(8/11), false positive rate was 4.55%(2/44), false negative rate was 6.82%(3/44), accuracy rate was 88.64% (39/44) (Kappa=0.762, P=0.001). Conclusion MRI is an accurate way to diagnose anterior cruciate ligament, particularly for absent ACL and complete tear, for partial tear ACL patients MRI should combine with other diagnosis to decrease false results.
