What will mri of knee show

When the ACL is torn in a sports injury you feel a pop and the knee gives out making it hard to walk. When the ACL tears more gradually there is often no specific moment or pop; knee pain and a sense that your knee cannot hold your weight comes on gradually. A ligament, like cartilage, does not show up on x-ray; therefore, a torn ACL is best seen on MRI and does not show up on x-ray. Arthritis is the result of inflammation on the knee.

This can occur due to trauma, gradual degeneration of the smooth cartilage in the knee joint osteoarthritis , or due to an underling problem rheumatoid arthritis. Arthritis causes thinning of the cartilage in the joint, rough surfaces, and can even result in loose bodies of cartilage floating in the fluid of the knee joint. All these changes in the knee due to arthritis can be seen on MRI; however, a knee x-ray is a valuable tool for your orthopedic surgeon to assess the overall stage of arthritis in your knee.

How do you know if your knee problem is serious? A knee problem is serious if you have any red flags sudden onset of pain so severe you cannot walk; deformity of the knee; a red, hot, swollen knee; history of cancer; unexplained weight loss; blood in your urine, stool, or vomit then the problem could be serious, and you need an urgent evaluation.

As you can tell, this type of urgent examination is most often done in a hospital emergency room. Fortunately, knee problems are rarely life threatening, and most of the time the evaluation is done outside the hospital.

So, do you need an MRI of your knee? If you have any red flags, then you need an MRI right away. Since most issues get better on their own without medical treatment then if you have no red flags and are within the first 3 weeks after injury then an MRI can wait. If your knee pain is not getting better on its own after three weeks you should see a doctor.

She will perform a physical examination, x-ray, and blood tests for infection. The results of these tests will decide whether you need an MRI. If you are over 55, your knee x-ray shows signs of arthritis, and the physical exam is not suspicious for a torn meniscus or ACL, then you have arthritis and should start rehabilitation; in this case an MRI is not needed. On the other hand, if your arthritis is not better after three weeks of rehabilitation such as physical therapy then you should try a hyaluronic acid synvisc, euflexxa, hyalgan, monovisc, orthovisc, supartz injection.

These injections help lubricate the synovial fluid of the knee, and often relieve pain for weeks to months. If you are still severely impaired from advanced arthritis of the knee despite hyaluronic acid injection, then it is time to see an orthopedic surgeon who specializes in partial knee replacement surgery or total knee replacement surgery for muscle sparing robotic assisted partial or total knee replacement. There is a slight chance of an allergic reaction if contrast material is used during the test.

But most reactions are mild and can be treated using medicine. If you breastfeed and are concerned about whether the contrast material used in this test is safe, talk to your doctor. Most experts believe that very little dye passes into breast milk and even less is passed on to the baby.

But if you are concerned, you can stop breastfeeding for up to 24 hours after the test. During this time, you can give your baby breast milk that you stored before the test. Don't use the breast milk you pump in the 24 hours after the test. Throw it out. Follow-up care is a key part of your treatment and safety.

Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to keep a list of the medicines you take. Ask your doctor when you can expect to have your test results.

An MRI can be used to detect chronic tendinitis inflammation of the tendon or tendon ruptures although this is usually apparent on physical examination.

In cases of tendinitis—such as that seen with "jumper's knee"—an MRI will usually reveal progressive knee injury in the form of scarring, inflammation, and malformations of the tendon itself.
