Keywords: Arthroscopy; bucket handle meniscal tear; magnetic resonance imaging; meniscus.
Objectives: This study aims to test the efficacy of magnetic resonance imaging (MRI) evaluation by a group who were blinded to the arthroscopic diagnosis in patients with known bucket handle meniscal tears.
Patients and methods: In this study, MRI scans of 28 patients who were operated due to bucket handle meniscal tear with sufficient documentation were evaluated. Radiographic evaluation was performed by two different groups, including an orthopedist and radiologist. In the first group, evaluation of MRI scans was performed by the specialists who were aware of the arthroscopic diagnosis and marked the defined MRI signs of bucket handle meniscal tear. In the second group, evaluation was done, remaining blinded to the diagnosis, with only initial complaints at admission. The second group also evaluated the MRI scans and marked the pathologic signs. The sensitivity of radiological signs marked by both groups was compared. Invariables were found using blinded evaluation.
Results: Double posterior cruciate ligament and free fragment in the intercondylar notch were invariable sensitivities found in the MRI scans by blinded evaluation. The sensitivity of coronal truncation, anterior flip and any free fragment signs were significantly decreased in the setting of blinded evaluation.
Conclusion: Preoperative differentiation of reparable buckethandle tears from irreparable is of utmost importance. As meniscal repair improves knee stability and functional results, surgical repair of meniscal injuries particularly in younger individuals who are scheduled for anterior cruciate ligament reconstruction have a positive effect on clinical outcomes.
