A tear of a meniscus is a rupturing of one or more of the fibrocartilage strips in the knee called menisci. When doctors and patients refer to "torn cartilage" in the knee, they actually may be referring to an injury to a meniscus at the top of one of the tibiae .
Magnetic Resonance Imaging (MRI): [5] [6] The gold standard for diagnosing bucket-handle tears. Key findings on MRI include: Double PCL sign: The displaced meniscal fragment mimics the appearance of a second posterior cruciate ligament (PCL) on sagittal images. Flipped meniscus appearance: The displaced fragment creates an abnormal signal ...

The examiner then rotates the leg internally while extending the knee to 90 degrees of flexion. If a "thud" or "click" is felt along with pain, this constitutes a "positive McMurray test" for a tear in the posterior portion of the lateral meniscus. Likewise, external rotation of the leg can be applied to test the posterior portion of the medial ...
It is usually happening on one side, without a previous history of trauma. SONK should be considered together with differential diagnosis of osteoarthritis, tear of medial meniscus, and tibial plateau fracture. SONK usually has a sudden onset of knee pain, while osteoarthritis has a progressive, gradual onset of knee pain. [2]
A discoid meniscus is a congenital anomaly of the knee found in 3% of the population (up to 15% in Asia). It typically affects the lateral meniscus and may be found bilaterally (20%). Instead of the narrow crescent shape, as seen in a normal meniscus above, a discoid meniscus is thickened, and has a fuller crescent shape.
grade 2: minor tears of less than one-half the thickness of the cartilage layer; grade 3: lesions have deep crevices of more than one-half the thickness of the cartilage layer; grade 4: the cartilage tear is full thickness and exposes the underlying (subchondral) bone; Doctors will often also measure the size of each defect.
Injuries to the ACL are common, 250,000 ACL injuries occur on an annual basis. This corresponds to a 1 in 3,000 chance of an individual sustaining an ACL injury. Ligaments in the ACL or meniscus are usually torn with an external force being applied to the knee joint. The ACL can be torn without an external force being applied [11]
