Where is the medial mensical root in the knee? What is the purpose of a j brace? Does popping of the knee joint mean that the meniscus is torn?

The Attachment: The meniscus is c-shaped. At each end is a firm attachment to the bone. That's the meniscus root. A j brace helps stabilize the patella (kneecap). A torn meniscus is one reason for the knee to pop. ...Read more

I have chronic clicking and clunking of the knee joint. What coul be the problem?  What is the difference of a displacement of the root or meniscus?

Could be arthritis: The clicking and clunking can be arthritis or a cartilage tear. The meniscus is a piece of cartilage that acts like a shock on a car. It goes in between the two bones. But like shocks on a car, it can wear out and tear. The second part of your question is the same thing. They are describing the part of the meniscus -- i.e. The root of the meniscus -- which is where it attaches to. ...Read more

Is a displacement of the medial meniscus root a tear? What kind of damage is being done every time the knee clunks?

Something slipping: In the knee there is both a medial meniscus and a lateral meniscus. The meniscus is cartilage and it can tear and it can slip. Slipping can be felt as you suggest but other things can cause a clunk like the patella - the kneecap. Imaging studies can actually show slippage. Does your knee lock. Locking is a common complaint of meniscus tears. To tell if you have damage you need evaluation. ...Read more

Does a displcement of the meniscal root mean that there is a tear? Where is the articular cartilage in the knee? What is the purpose of having that?

Meniscus - surgery: You are quoting detailed anatomy inside the knee, likely from an MRI report. It describes a tear in the meniscus cartilage, which lines the inside of the knee so bones can glide against each other smoothly. This usually needs surgery to correct, but the surgery can be done through a tiny incision with a scope. Find more info @ http://orthoinfo.Aaos.Org/topic.Cfm?Topic=a00358. ...Read more

What are the symptoms of a meniscus tear? What does it mean when a MRI says a displacement at the meniscus root? Does that cause a knee to lock?

What are the symptoms of a meniscus tear? What does it mean when a MRI says a displacement at the meniscus root? Does that cause a knee to lock?

Giving way: Meniscal tears usually cause mechanical instability. The primary symptom is buckling or giving out. A displaced meniscus can cause the knee to lock. The meniscal root is where it attaches either in the front or back of the knee. Depending on your age it can be repaired or removed but is almost always a surgical treatment. See a good orthopedic surgeon. ...Read more

What causes a knee joint to lock up? Is a displacement ot the mensicus root considered a tear? What is medium size joint effusion mean?

What causes a knee joint to lock up? Is a displacement ot the  mensicus root considered a tear? What is medium size joint effusion mean?

A meniscus tear: The most common cause of a locked knee is a large meniscus tear. When this happens, a portion of the meniscus gets stuck in a bad spot. This doesn't allow the knee to move freely, causing it to lock. Displacement of the meniscus root is a certain kind of tear. Sometimes, it can be repaired which can be hard. See an experienced surgeon. An effusion is fluid in the knee, likely from the tear. ...Read more

What are the symptoms of a displaced meniscus? Is a displacement the same as a medial extrusion? Please explain

Meniscal tears: A displaced meniscus tear can cause clicking, catching, and locking. A displaced tear may be displaced into the center of the joint which will be more symptomatic. An extruded meniscus is displaced out of the joint and itself does not cause pain but the joint space narrowing can cause pain. Removal or meniscectomy of an extruded meniscus usually does not relieve pain. ...Read more
