“…Consistent with our results, Manco et al could show a sensitivity of 88.5% and a specificity of 95.5% [ 12 ]. Considering additional soft-tissue reconstructions, the sensitivity in our study increased by 4 to 94.7% and the specificity increased to 100%.…”

“…While some single case reports have presented the finding of a bucket handle meniscal tear on CT, the sensitivity and specificity of CT scans for this type of injury are not well established [ 10 ]. Most studies on the diagnostic accuracy of CT and MRI for meniscal injuries are from the 1980s and are based on outdated scanners [ 11 , 12 , 13 ]. A better understanding of the sensitivity and specificity of CT scans for detecting dislocated bucket handle meniscal tears could have significant implications for the evaluation and management of acute knee injuries, potentially reducing the need for more invasive diagnostic procedures and leading to earlier interventions and improved patient outcomes.…”

(1) Background: Meniscal tears are amongst the most common knee injuries. Dislocated bucket handle meniscal tears in particular should receive early intervention. The purpose of this study was to evaluate the diagnostic performance of CT in detecting dislocated bucket handle meniscal tears compared with the gold-standard MRI and arthroscopy. (2) Methods: Retrospectively, 96 consecutive patients underwent clinically indicated CT of the knee for suspected acute traumatic knee injuries (standard study protocol, 120 kV, 90 mAs). Inclusion criteria were the absence of an acute fracture on CT and a timely MRI (<6 months). Corresponding arthroscopy was assessed. Two experienced musculoskeletal radiologists analyzed the images for dislocated bucket handle meniscal tears, associated signs thereof (double posterior cruciate ligament sign, double delta sign, disproportional posterior horn sign), and subjective diagnostic confidence on a 5-point-Likert scale (1 = ‘non-diagnostic image quality’, 5 = ‘very confident’). (3) Results: Dislocated bucket handle meniscal tears were detected on CT by standard three-plane bone kernel reconstructions with a sensitivity of 90.7% and a specificity of 99.3% by transferring the knowledge of established MRI signs. The additional use of soft-tissue kernel reconstructions in three planes increased the sensitivity by 4.0% to 94.7%, specificity to 100%, inter-rater agreement to 1.0, and the diagnostic confidence of both readers improved to a median 4/5 (‘confident’) in both readers. (4) Conclusions: Trauma CT scan of the knee with three-plane soft-tissue reconstructions delivers the potential for the detection of dislocated bucket handle meniscal tears with very high diagnostic accuracy.

“…In der Humanmedizin zählt die Computertomographie auch bei Verdacht auf Meniskusschäden zu den etablierten Verfahren. Sie wird hier als Nativ- (Manco et al, 1986;Passariello et al, 1 983) oder Kontrastuntersuchung (Ghelman, 1 985; Schuler et al, 79BZ) eingesetzt und erwies sich in einer arthroskopisch kontrollierten Studie als sehr zuverlässig (Jerosch et al, 1991). lm Bereich der Pferdeorthopädie ist die Computertomographie ein relativ neues Verfahren, konnte inzwischen jedoch bei verschiedenen klinischen Fragestellungen zusätzliche lnformationen beisteuern (Hanson et al, 1996;O'Callaghan, 1991;Tietje, 1994Tietje, und 1997Wisner et al, 7997).…”

“…For the detection of tears, both CT arthrography and MR imaging have the same accuracy. [17][18][19][20][21] CT has the added advantage of clearly depicting the osseous structures, and due to its higher spatial resolution, very small tears are more clearly depicted (Fig. 2).…”

As the therapeutic options for the treatment of meniscal lesions evolve, so do the challenges in both preoperative and postoperative imaging of the meniscus. Ideally, an imaging modality should accurately depict the meniscus and any meniscal lesions in such a way that the best treatment option can be chosen. It should also be able to depict the treated area, accurately assess the follow-up of treatment, and differentiate the findings associated with the treatment from recurrent lesions. At this moment magnetic resonance (MR) is the imaging modality of choice for the virgin meniscus, the operated meniscus, and the transplanted meniscus. In all these situations, unenhanced MR imaging accurately displays the meniscus and the possible lesions. Only in patients with sutured menisci can the performance of MR be improved by intra-articular contrast administration. Computed tomographic arthrography has a similar accuracy as MR imaging for the detection of meniscal lesion, and it is especially valuable for the evaluation of menisci in the presence of orthopaedic hardware. It remains, however, an invasive technique that requires ionizing radiation.
