Menisk käkled
Meniskerna är två broskkuddar som det finns två av i vardera knäled. Dessa två broskbitar ligger på varsin sida av knäet inne i själva leden. De viktigaste funktionerna är: Att bilda en "grop" där lårbenet kan röra sig utan att benet går ur led i förhållande till underbenet. A torn meniscus is one of the most common knee injuries. Any activity that causes you to forcefully twist or rotate your knee, especially when putting your full weight on it, can lead to a torn meniscus.
What Is a Meniscectomy?
Each of your knees has two C-shaped pieces of cartilage that act like a cushion between your shinbone and your thighbone. A torn meniscus causes pain, swelling and stiffness. You also might feel a block to knee motion and have trouble extending your knee fully. The meniscus is a C-shaped piece of tough, rubbery cartilage that acts as a shock absorber between the shinbone and the thighbone. It can be torn if you suddenly twist your knee while bearing weight on it.
Conservative treatment — such as rest, ice and medication — is sometimes enough to relieve the pain of a torn meniscus and give the injury time to heal on its own. In other cases, however, a torn meniscus requires surgery. 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:.
Contact your doctor if your knee is painful or swollen, or if you can't move your knee in the usual ways. A torn meniscus can result from any activity that causes you to forcefully twist or rotate your knee, such as aggressive pivoting or sudden stops and turns. Even kneeling, deep squatting or lifting something heavy can sometimes lead to a torn meniscus. In older adults, degenerative changes of the knee can contribute to a torn meniscus with little or no trauma.
Performing activities that involve aggressive twisting and pivoting of the knee puts you at risk of a torn meniscus. The risk is particularly high for athletes — especially those who participate in contact sports, such as football, or activities that involve pivoting, such as tennis or basketball. A torn meniscus can lead to a feeling of your knee giving way, inability to move your knee as you usually do or persistent knee pain.
You might be more likely to develop osteoarthritis in the injured knee. Mayo Clinic does not endorse companies or products. Advertising revenue supports our not-for-profit mission.
