Abstract

Objective To determine the overall diagnostic accuracy of the McMurray and joint line tenderness (JLT) tests for the detection of meniscal lesions. Design Secondary analysis of a prospective observational study. Setting Orthopedics outpatient clinic, university hospital. Participants Patients (N=56) with suspected nonacute meniscal lesions who underwent knee arthroscopy. Interventions Not applicable. Main Outcome Measures Diagnostic accuracy of the McMurray and JLT tests as determined by receiver operator characteristic analysis. Results The McMurray test showed higher accuracy (area under the curve [AUC],.69; SE,.079) than the JLT test (AUC,.58; SE,.084). Conclusions The McMurray test, although presenting a higher diagnostic accuracy than the JLT test, does not suffice as a standalone diagnostic procedure for chronic meniscal lesions. The test may still be valuable to guide the diagnosis in cases with highly suspected meniscal tears.
