Abstract

Objective Bucket-handle tear is a displaced vertical longitudinal tear of the meniscus. Several signs of the tear have been described on MRI but none in the axial plane. We propose to describe such a sign named the V-sign that is seen at the junction of the displaced fragment and the meniscus, which is in place. Materials and methods MRI imaging of 25 surgically proven bucket-handle tears was reviewed for presence of the V-sign. Two control groups, one with normal menisci (n=75) and one with surgically proven non-bucket-handle tears (n=25), were also evaluated. Comparisons for presence or absence of the Vsign were performed among the three groups, and also for other commonly associated signs such as double PCL sign, double delta sign, and presence of ACL tear. Also, sensitivity, specificity, and positive and negative predictive values were calculated. Results Among those with bucket-handle tear, 72% demonstrated the V-sign while no participant in either control group had the V-sign (P≤0.001). The V-sign occurred in 38% of those with double PCL sign, 55.6% with ACL tear, and 66.7% with double delta sign. The V-sign had higher sensitivity and negative predictive values than other signs related to bucket-handle tear. Conclusion The V-sign, when seen on an axial plane image, is highly suggestive of bucket-handle tear. Our data suggest the benefit of using the V-sign for detecting bucket-handle tears, perhaps even above other commonly used approaches.
