MRI gives a good picture of the size of a meniscus tear and where it is. It also shows ligaments, cartilage, and tendons. MRIs of the knee are helpful to identify a meniscus tear and to find any related injuries to the ligament, cartilage, and tendons.
Because a torn meniscus is made of cartilage, it won't show up on X-rays. But X-rays can help rule out other problems with the knee that cause similar symptoms. MRI . This uses a strong magnetic field to produce detailed images of both hard and soft tissues within your knee.
An MRI is 70 to 90 percent accurate in identifying whether the meniscus has been torn and how badly. However, meniscus tears do not always appear on MRIs. Meniscus tears, indicated by MRI, are classified in three grades. Grades 1 and 2 are not considered serious.
The McMurray test is a series of knee and leg movements healthcare providers use to diagnose a torn meniscus. It's an in-office physical exam, which means your provider can perform it without any special equipment or a separate appointment.

It's not unusual for patients who are suffering with knee pain to have a “negative” MRI. This situation is relatively common. In cases of a strain or inflammation the MRI may indeed be negative for structural problems.
The sensitivity was significantly lower for tears located in the posterior horn and for vertically oriented tears. Therefore, special attention should be given to the peripheral posterior horns of the meniscus, which are common sites of injury that could be easily missed on MRI.
If you've torn your meniscus, it might take 24 hours or more for pain and swelling to begin, especially if the tear is small. You might develop the following signs and symptoms in your knee: A popping sensation. Swelling or stiffness.

Some exercises are too strenuous for people with meniscus tears. A person should not: do deep squats. do any exercise that involves pivoting or that otherwise twists the knee.
Medial meniscal root tears are associated with poor subjective knee function (24), and a relatively high proportion of these patients (31 %) require a knee replacement within five years (35), emphasising that medial root tears are part of a general degenerative process.
In severe tears, pieces of the torn meniscus can move into the joint space. This can make your knee catch, pop, or lock. You may not be able to straighten it. Your knee may feel "wobbly" or buckle without warning.

A cortisone shot usually does not help in healing of the meniscus and, hence, does not improve any mechanical symptoms. If a meniscus is repairable, then a cortisone shot is not preferred as it may impair healing of the meniscus.
Meniscal pain occurs during torsional, weight bearing knee movements (classically pivoting on the knee while walking) as a sharp stab lasting several seconds, often followed by a dull ache for several hours.
