The bucket-handle meniscal tear is a specific type of meniscal injuries which has specific signs on MRI. An attached fragment displaced away from the meniscus with any type of tear causes bucket-handle tear of the meniscus. Magnetic resonance imaging (MRI) is the most commonly used diagnostic tool for meniscal injuries. We present a case of free medial meniscal fragment which mimics the dislocated bucket-handle tear on MRI. The presence of "fragment within the intercondylar notch sign" and "the absence of the bow tie sign" may be an indication of a free meniscal fragment. This should be considered during diagnosis.

Introduction: A meniscus tear ranks among the most common sports-related injuries, especially among athletes. Sudden, twisting movements, such as pivoting to catch a ball, usually in contact sports, and can tear the meniscus. Magnetic resonance imaging (MRI) technology is extensively utilized for identifying meniscal tears.

Background/objectives: MRI is the gold standard for detecting meniscal tears; however, ultrasound may readily detect meniscal changes, obviating the need for MRI. We aim to (1) determine ultrasound sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy in detecting meniscal changes, and (2) describe characteristic meniscal changes in US and their prevalence.
Methods: A retrospective analysis of knee ultrasound scans for the presence of medial and lateral meniscal tears was conducted.

Purpose: To compare the outcomes of patients undergoing partial meniscectomy preoperatively identified with the "meniscal comma sign" with those undergoing meniscectomy with other tear patterns.
Methods: Patients with meniscal "comma sign," as indicated by a query of magnetic resonance imaging reports, were screened using the search terms "meniscotibial recess," "meniscus perched over the medial tibial margin," or other search terms by radiologists between January 2008 and November 2019. Patients were matched and chart review was done for demographics, revision surgery, and progression to total knee arthroplasty.

Background: Bucket-handle meniscal tears are large longitudinal vertical meniscal tears that have an attached fragment flipped into the intercondylar notch. Meniscal repair attempts to restore the function of the meniscus and aims to preserve joint mechanics. Alternatively, meniscectomy results in quicker recovery but may lead to future degeneration.

The posterior cruciate ligament (PCL) is the largest and strongest intra-articular ligament of the knee joint and the primary posterior stabilizer. PCL injuries are less frequent than other knee ligament injuries and are typically combined with meniscal and chondral injuries or in the context of multiligamentous injuries. It is critical to properly diagnose and treat these lesions in order to avoid the risk of PCL insufficiency, subsequent knee instability, and early osteoarthritis.
