A torn meniscus is confirmed with a Magnetic Resonance Imaging (MRI) scan, the gold standard for visualizing soft tissues, though doctors use physical exams with maneuvers like the McMurray test or Thessaly test to suspect one, and X-rays rule out other issues like arthritis. An MRI provides detailed images showing the tear's location and severity, guiding treatment decisions.
Imaging tests
But X-rays can help rule out other problems with the knee that cause similar symptoms. Magnetic resonance imaging (MRI). This uses a strong magnetic field to produce detailed images of both hard and soft tissues within your knee. It's the best imaging study to detect a torn meniscus.
Treatment for meniscus tears focuses on controlling pain and inflammation. Initial management of meniscus tears involves the common approach in sports medicine of RICE: Rest, Ice, Compression, and Elevation of the affected leg. If needed, pain medication can also be prescribed. Crutches can be used to move around.
Can a torn meniscus cause ankle swelling? Following surgery for a torn meniscus, excess fluid in the body may reach the ankle and cause swelling that will subside within days/weeks.
For lateral meniscus tears McMurray is the most sensitive, specific, and accurate test with the largest positive predictive value and likelihood ratio. For tears in anterior cruciate ligament, medial and lateral menisci, together, joint-line tenderness is the most sensitive and McMurray is the most specific.
You may not need magnetic resonance imaging (MRI) or arthroscopy. If your symptoms are moderate to severe, or if your doctor thinks you have a meniscus tear and other knee injuries, your doctor may recommend either an MRI or arthroscopy. Some doctors prefer to do arthroscopy instead of MRI.
Three key signs of a meniscus tear are pain (especially with twisting or bending), swelling and stiffness, and a catching, locking, or popping sensation in the knee, sometimes accompanied by difficulty fully straightening the leg. You might feel a "pop" at the moment of injury, and symptoms often worsen over a few days.
A patient with a meniscus tear will complain of knee pain and swelling on the inner (medial) or outer (lateral) side of the knee. There will be pain with deep knee bending, walking, twisting, and exercise. There can be a sensation of the knee giving way and mechanical symptoms such as locking, catching, or clicking.
Perimeniscal injections: a new gold standard for meniscus tear treatment. Perimeniscal injections offer a promising new pathway in the conservative management of degenerative meniscus tears. Degenerative meniscus tears are a common cause of persistent knee pain, especially in ageing and active populations.
Iliotibial Band Syndrome. ITBS is a common source of pain in athletes. Although the iliotibial band (ITB) can become inflamed proximally and present as hip pain, it most commonly presents at the lateral aspect of the knee and can mimic a lateral meniscus tear.
Meniscus damage is most frequently seen between the ages of 15 and 30 or between the ages of 45 and 70. Damaging or losing part of the meniscus can lead to short-term symptoms related to the meniscus damage and/or longer-term symptoms of arthritis due to the lack of the knee's normal shock absorber.
Understand exactly what surgery is planned, along with the risks, benefits, and other options. If you take a medicine that prevents blood clots, your doctor may tell you to stop taking it before your surgery. Or your doctor may tell you to keep taking it. (These medicines include aspirin and other blood thinners.)
One study published in the American Journal of Sports Medicine found that patients who received PRP injections reported reduced pain and improved function compared to those who underwent surgery. These findings suggest that PRP therapy can be a highly effective and non-invasive treatment option for meniscus tears.
There is a specific meniscal test called the 'McMurray's test' that your physiotherapist may additionally carry out to help establish your diagnosis.
Symptoms of a meniscus tear may be different for each person, but some of the most common symptoms are: Pain in the knee joint: usually on the inside (medial), outside (lateral) or back of the knee. Swelling. Catching or locking of the knee joint.
Pain, especially when twisting or rotating your knee. Difficulty straightening your knee fully. Feeling as though your knee is locked in place when you try to move it. Feeling of your knee giving way.
Corticosteroid Injections
Although corticosteroids injected directly into the knee do not heal a meniscus tear, they may reduce swelling and discomfort. Some people may experience long-lasting relief. Your doctor may inject a small amount of anesthetic into the knee along with corticosteroids.
Arthroscopic Meniscus Surgery
Arthroscopy is a minimally invasive procedure that uses a special device (called an arthroscope) equipped with a light, camera and magnifying lenses. An arthroscope allows the surgeon to see into the knee joint without creating a large incision (cut).
The most common side effect is mild pain and swelling at the injection site that goes away on its own. About 1% of people have a more severe reaction called an injection flare. It causes fluid to accumulate in the joint, with significant swelling and pain.
Symptoms may go away but can come back from overuse or when you do activities that involve twisting. The pain may come and go over a period of years if the tear isn't treated. Larger tears usually cause more pain and immediate swelling and stiffness.
Not everyone who tears their meniscus will need to wear a brace, but some people do. If you need to wear a knee brace, you may need to wear it for up to six weeks or longer. Sometimes it's necessary to use crutches and a knee brace in the early stages of your recovery.
Cycling in Rehabilitation
Riding a stationary bike is often recommended during rehabilitation following surgery to repair a torn meniscus, according to the AAOS. Stationary bikes can be easily programmed to provide little resistance to your knee joint. They can also help you regain normal range of motion in your knee.
Over 4-6 weeks, the pain and swelling may decrease and activities of daily living may become tolerable. However, athletic activities may reproduce pain and swelling. Sometimes even activities of daily living such as going up and down stairs or getting in and out of cars may produce pain in a knee with a torn meniscus.
Arthritis (a breakdown of cartilage in the joints) can also lead to a meniscus tear. It's also a common sports injury in people who play sports, even in children and teenagers.
Nonsurgical treatments, such as anti-inflammatory medications and rehabilitation with a physical therapist may help some people with a torn meniscus. Other patients will need surgery, which entails either trimming or repairing the meniscus. Treatments may also depend on whether the tear is traumatic or degenerative.
