A bucket-handle tear of the knee is a specific type of meniscal injury characterized by a longitudinal tear of the medial or lateral meniscus, where a displaced inner fragment resembles the appearance of a "bucket handle". [1] This displaced meniscal fragment often remains attached at the anterior and posterior horns but dislocates into the ...
Bucket-handle tear of the lateral meniscus (red). Medial meniscus intact (green). MRI, coronal T2 *-weighted GRE sequence. X-ray images (normally during weightbearing) can be obtained to rule out other conditions or to see if the patient also has osteoarthritis. The menisci themselves cannot be visualised with plain radiographs.
The absent bowtie sign is a radiologic sign indicative of a meniscal tear in the knee joint. On sagittal magnetic resonance (MR) images, the body of the meniscus normally looks like a bow tie, with two distinct segments. The absent bowtie sign is present when there is a lack of two segments seen on consecutive sagittal MR images. [1]
A bucket-handle tear is a specific type of longitudinal meniscal tear in which a fragment of the torn meniscus displaces toward the intercondylar notch of the knee. The displaced fragment often remains attached at its anterior and posterior horns but flips centrally into the notch. [4]
Damage to the outer third of the meniscus has the best healing potential because of the blood supply, but the inner two thirds of the medial meniscus has a limited blood supply and thus limited healing ability. Large tears to the meniscus may require surgical repair or removal. In terms of a meniscus tear, the doctor can categorize the injury ...
If the tear causes continued pain, swelling, or knee dysfunction, then the tear can be removed or repaired surgically. The unhappy triad is a set of commonly co-occurring knee injuries which includes injury to the medial meniscus.
A tear in the meniscus may cause a pedunculated tag of the meniscus which may become jammed between the joint surfaces. To perform the test, the knee is held by one hand, which is placed along the joint line, and flexed to complete flexion while the foot is held by the sole (of the foot) with the other hand.
Bucket-handle tear of the lateral meniscus (red). Medial meniscus intact (green). MRI, coronal T2 *-weighted GRE sequence. The MRI image in the article. Is it the left knee or the right? Comes.amanuensis 12:20, 10 August 2013 (UTC)
