A torn meniscus is quite possibly the most widely recognized knee wound. Also, there is not just one way where you can get your meniscus torn. There are different types of meniscus tear.
Any action that makes you strongly turn or pivot your knee, particularly when putting your full weight on it, can prompt a torn meniscus.
Every one of your knees has two C-shaped bits of the ligament that behave like a pad between your shinbone and your thighbone (menisci). The shinbone is the tibia and the thigh bone is the femur.
A torn meniscus causes pain, tenderness, and swelling. You likewise may feel a problem with knee movement. You will also experience difficulty extending your knee completely and feel like your knee locks while walking.
Anatomy Of The Knee And Meniscus
There are two menisci in our knees :
The major meniscal functions are:
In the lacking lateral cruciate ligament, menisci fill in as joint stabilizers. It gives the articular ligament sustenance. It helps to carry out movement without friction.
It also works with joint locking, forestall hyperextension, and ensures the joint stays put.
During knee flexion, the femoral condyles glide posteriorly on the tibial level related to the tibial interior turn. The lateral meniscus goes through double the anteroposterior interpretation of the average meniscus during knee flexion.
This interpretation keeps the femur from reaching the back edge of the tibial plateau.
The meniscus is partitioned into three zones: the red-red, the red-white-and the white-white.
The zones are separated by vascularization and hence recuperating potential. The red-red zone is the optimal zone of the meniscus. It is excellent vascularized and has a decent mending rate.
The red-white zone is the center third with less vascularization but can heel at times. The white-white zone has no blood vessels at all and accordingly can’t mend.
What Is A Meniscus Injury?
Patients portray meniscal tears in an assortment of ways. There are also many types of meniscus tear. Knowing where and how a meniscus was torn assists the specialist in deciding the best treatment.
Area – A tear might be situated in the front, body, or back. A back tear is the most well-known. The meniscus is separated into the external, center, and inward thirds.
The third where the tear is found will decide the capacity of the tear to recuperate since blood supply in that space is basic to the mending cycle. Tears in the external 1/3 have the most obvious opportunity with regards to recuperating.
What Are The Symptoms Of Types Of Meniscus Tear
Intense tears are frequently sports-related. They are generally the aftereffect of a twisting injury in the more athletic and sporty adult populace.
Manifestations of an intense tear are generally pain, swelling, and development abnormalities. At the point when the tear impedes typical knee movement, the knee can “catch” or “bolt” as it moves.
Degenerative tears are more normal in the elder populace. The patient may encounter continued swelling, yet, frequently can’t remember a particular physical issue.
The swelling additionally might be the aftereffect of a physical issue brought about by a minor development. Mechanical manifestations, for example, knee bolting, frequently exist. Or then again, the patient may essentially encounter torment.
Complete- A tear is considered complete if it goes completely through the meniscus and a piece of the tissue is isolated from the remainder of the meniscus.
On the off chance that the tear is still part of the way appended to the body of the meniscus, it is considered deficient.
Partial- A partial tear can be steady or temperamental. A steady tear doesn’t move and may mend all alone.
A precarious tear permits the meniscus to move strangely and is probably going to be an issue on the off chance that it’s anything but precisely adjusted.
There are 4 major types of meniscus tears. These include:
1) Radial Tear
Radial tears of the meniscus, are the most well-known kind of meniscus tear. These tears are inside the avascular zone of the meniscus, where there is no blood supply, and in this way, there is little limit to these tears to mend.
2) Complex Tear
A complex tear implies there is a blend of tear patterns.
Ordinarily complex tears are not treated with meniscus surgery. In some conditions, a portion of the torn meniscus can be taken out, while different bits can be fixed.
3) Horizontal Tear
A horizontal meniscus tear is probably the least common kind of tear to fix in the knee. Maybe than eliminating the segment of the meniscus that is harmed, the specialist will attempt to sew together the circumferential strands of the meniscus back together.
The area is vital to meniscus fix. The more vascular segments of the meniscus, near the external edge, have a more noteworthy potential for mending than do regions that are all the more halfway situated in the knee.
4) Bucket Handle Tear
A bucket handle tear is when the meniscus tears from the between in a horizontal way such that it forms a flap-like structure that represents a bucket handle and can turn anteriorly and posteriorly.
Alternate ways you can encounter a bucket handle tear include:
- climbing steps
- hunching down
- twisting of the knee while taking a stumble when strolling
Now and again, you can have a persistent bucket handle tear because of degenerative changes in your knee joint.
At the point when joint pain causes the bones of your knee joint to rub against one another, regions can get sporadic and unpleasant rather than smooth. These progressions make it’s anything but a can deal with tear to happen.
Other less common types of meniscus tear include – longitudinal tear, vertical tear, and horizontal types of meniscus tear.
Diagnosis Of Types Of Meniscus Tear
The doctor will initially take a background marked by the injury to help decide whether the signs and indications may propose meniscal harm and the type of meniscus tear.
Next, the specialist will assess the knee for swelling and tenderness in a physical assessment. The knee will be tender when pushed on the harmed side where the tibia and femur meet.
The McMurray’s test is a test where the specialist applies pressing factor and moves the knee from directly to twisted to straight again to perceive what positions cause torment or getting (signs of a meniscal tear).
The specialist may utilize imaging to survey the measure of harm and types of meniscus tear. X-rays can show any breaks or ligament conditions in the knee. A thin joint space or bone changes show bone-on-bone scouring and joint inflammation.
If the analysis is not yet satisfactory, an MRI (Magnetic Resonance Image) might be requested to uncover harm to ligaments and menisci. This test is 70 – 95% exact in uncovering from the different types of meniscus tear, and can likewise show any tendon harm.
The Bottom Line For Types Of Meniscus Tear
Although there are various types of meniscus tear, it is important to rule out from all the types of meniscus tear, which one the individual has suffered. This will help in charting out the appropriate treatment protocol for a speedy recovery.
