In a prospective study, the accuracy of arthrography was compared to that of the anterior drawer sign in the diagnosis of anterior cruciate ligament tears. In 29 surgically proven cases, arthrography had a sensitivity of 91%, specificity of 89%, and predictive value of 83%. The anterior drawer sign had a sensitivity of 91%, specificity of 100%, and predictive value of 100%. Reasons for false-positive and false-negative arthrograms and drawer signs are discussed. Although arthrography is accurate in determining anterior cruciate abnormalities, it is no more reliable than the anterior drawer sign. Physical examination should remain the principal means of cruciate diagnosis.
在一项前瞻性研究中，对关节造影术和前抽屉试验诊断前交叉韧带撕裂的准确性进行了比较。在29例经手术证实的病例中，关节造影术的敏感度为91%，特异度为89%，预测值为83%。前抽屉试验的敏感度为91%，特异度为100%，预测值为100%。文中讨论了关节造影和抽屉试验假阳性及假阴性的原因。虽然关节造影术在确定前交叉韧带异常方面是准确的，但它并不比前抽屉试验更可靠。体格检查仍应是交叉韧带诊断的主要手段。
