Knee Meniscus Injury
Meniscus is a C-shaped pad of cartilage placed inside the knee joint between femur and tibia, one at medial and the other at the lateral aspect of the joint. Meniscus play a big role in absorbing shock from the impact during weight bearing and also providing stability of the joint.
Meniscus injury is very common. It can be an isolated injury or can be associated with other ligament injury of the knee joint. Meniscal tear can affect different parts of the meniscus and with different patterns or can be a different combination of all. Common patterns of injuries are bucket handle, radial, transverse, and can affect body, horn and root. Pain, swelling, locking are usually the common symptoms. MRI is the investigation of choice for diagnosis.
Though meniscus plays a great role in absorbing shock of impact from weight bearing its injury has a huge impact in progression of arthritis. Preserving meniscus by repair has a better prognosis than resection. But sometimes sacrifice becomes inhabitable.
