Abstract:
Objective To evaluate the value of MRI in diagnosing the bucket handle tear (BHT) of the knee meniscus.Methods Eighty four knees which underwent both MRI and arthroscopy (AS) examinations were analyzed. Results of AS were used as golden standard to evaluate the results of MRI. The evaluating criteria included primary reports, central displaced fragments of meniscus (CDFM), double posterior cruciate ligament sign (DPCLS) and the absent bow tie sign (ABTS). Results For MRI diagnosing BHT, the sensitivity and specificity of primary reports were 43% and 87%, respectively; the sensitivity and specificity of CDFM were 72% and 87%, respectively; the sensitivity and specificity of the DPCLF were 31% and 97%, respectively; and the sensitivity and specificity of the ABTS were 71% and 69%, respectively.Conclusions When MRI was applied to diagnose BHT, the CDFM had higher sensitivity and specificity, while the ABTS had higher sensitivity and lower specificity. The DPCLF had the highest specificity and the lowest sensitivity.
