Magnetic resonance imaging is the gold standard, first choice for investigation of suspected meniscal tears.
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.
The Childress (duck waddle) test provokes compressive force on the posterior horn of the meniscus causing pain. The Steinmann I test is carried out with the knee flexed at 90 degrees and a sudden external rotatory force is applied on the tibia to test the medial meniscus. The result is pain along the medial joint line.
You will have a physical examination to find out if you have a torn meniscus and to rule out other knee injuries. Your doctor will check both knees for tenderness, range of motion, and knee stability. X-rays are usually done. Based on your symptoms and the physical examination, your doctor may diagnose a meniscus tear.
There is often sharp pain when you twist or squat. 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.
Continuing to walk on the affected leg can aggravate your symptoms, making pain and stiffness worse in as little as a few days. Plus, suffering a torn meniscus may also increase your risk of complications, like developing osteoarthritis in that knee.
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.
Meniscus tears are the most frequently treated knee injuries. Recovery will take about 6 to 8 weeks if your meniscus tear is treated conservatively, without surgery. If your symptoms persist after 3 months or your symptoms become significant, your doctor may recommend surgery to repair the tear.
Will a knee brace help a torn meniscus? Yes. Although knee braces do not heal or treat your meniscus tear directly, they can provide extra support and stability for your knee while your meniscus injury heals. A good brace will protect your knee and take the pressure off your meniscus, allowing it to rest.
AM3101 is an injectable drug being developed as a therapy to reduce the frequency of complications and morbidities associated with failed meniscal repair surgery. Meniscal tears, particularly in the portion of the tissue lacking sufficient blood supply, are often irreparable and require removal of the disease tissue.
Avoid activities that aggravate your knee pain, especially any activity that causes you to twist, rotate or pivot your knee. If your pain is severe, using crutches can take pressure off your knee and promote healing.
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.
Most meniscal tears improve with time and physiotherapy. Physiotherapy will include load modification e.g. reducing your running and walking and reduction or avoidance of the movements and activities that make your pain or swelling worse. This advice will also be accompanied with a comprehensive exercise programme.
Left untreated, a meniscus tear can limit your daily life and ability to participate in exercise and sports. In serious cases, it can develop into long-term knee problems, like arthritis.
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.
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.
Another clear sign of a meniscus tear is a general lack of movement. The injured person will be unable to walk or apply pressure on the knee without pain. The knee becomes difficult to move, and the person may even be unable to stand without assistance. A lack of mobility is a clear sign that medical help is needed.
Range of motion may be limited due to pain, swelling, and/or mechanical limits from the tear. Daily activities such as walking up and down the stairs, walking down a hill, kneeling, and squatting are often made difficult due to increased pain in the knee.
A horizontal meniscus tear is one of the easiest types of tears to repair in the knee. Rather than removing the portion of the meniscus that is damaged, the surgeon will try to sew together the circumferential fibers of the meniscus back together.
Without a meniscus, you might gradually develop knee pain and arthritis of your joint. Replacing your meniscus may provide significant pain relief. It may also help prevent arthritis in your joint. This can develop when your cartilage becomes frayed and rough.
Rest your knee when possible. Do not squat or kneel. Take pain medicines exactly as directed.
