Types of Meniscus Tear
Determining the type of meniscus tear is an important factor in drawing up a treatment plan that is specific not just to the individual’s health but also to the injury. In general, there are six common types of meniscus tears.
Intrasubstance or Incomplete Tear: This type of tear is the most common where the meniscus is only partially torn. This type of tear is seen as a natural occurrence due to wear and tear as the body ages. Incomplete tears start appearing around the age of 20 and 30. These tears usually do not need any surgical intervention and are termed as stable injuries.
Radial Tear: This type of tear is the most common that requires surgery. The tear occurs in the avascular zone, or the area that does not receive any blood supply. This makes healing of the tear near impossible and the only option is to remove the damaged parts of the meniscus.
Horizontal Tear: A horizontal tear can be repaired surgically depending on its location. If it is located in the vascular region, then it can be simply stitched together and the tear will heal. However, of the tear is located in the avascular region then healing will not be possible and the damaged portion will have to be removed.
Flap Tear: This type of tear is rare. A portion of the meniscus comes away as a flap and gets caught in the knee. The offending flap can be removed surgically to ease movement in the joint.
Complex Tear: This type of tear is a combination of different types of tears and hence is hard to repair. This tear is usually a combination of a radial tear and a horizontal tear and is usually not repaired.
Bucket-Handle Tear: This a large type of horizontal tear that required urgent medical care. Because a large portion of the meniscus is torn, it could result in limited motion of the knee or even cause the knee to get stuck. To restore movement to the knee, immediate surgical attention will be required.
