The major meniscal functions are:
  • to alter the pressure across the knee during weight-bearing
  • Act as a shock absorber
  • fill in as optional joint stabilizers
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.
The femoral condyles glide posteriorly on the tibial level related to the tibial interior turn during knee flexion. 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.

Degenerative tears are more normal in the elder populace, mostly an early sign of osteoarthritis. 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.
  • 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.
  • A partial tear can be steady or temperamental. A steady tear doesn’t move and can mend all alone.

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 significant 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. It forms a flap-like structure that represents a bucket handle and can turn anteriorly and posteriorly.

The McMurray’s test is 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 narrow joint space or bone changes show bone-on-bone scouring and joint inflammation.
