Meniscus tears can occur during a rotating movement while bearing weight, such as when twisting the upper leg while the foot stays in one place during sports and other activities.
The ends of the 3 bones in the knee — the femur, tibia, and patella — are covered with cartilage. Cartilage is a smooth material that covers the ends of the bones and cushions them where they meet. It allows the joint to move easily and acts as a shock absorber. Between the bones of the knees are 2 crescent-shaped discs of connective tissue, called menisci. These also act as shock absorbers, protecting the lower part of the leg from the weight of the rest of the body.
Meniscus tears can occur during a rotating movement while bearing weight. One example would be twisting your upper leg while the foot stays in place during sports and other activities. Tears can be minor, with the meniscus staying connected to the knee, or major, with the meniscus barely attached to the knee by a thread f cartilage.
Symmptoms of a torn meniscus may be different for each person. Some of the most common symptoms are:
Pain, especially when holding the knee straight
Swelling and stiffness
Knee may click or lock
Knee may feel weak
The symptoms of a torn meniscus are similar to other medical conditions or problems. Always see your health care provider for a diagnosis.
In addition to a complete medical history and physical examination, diagnostic procedures for a torn meniscus may include the following:
X-ray. A diagnostic test that uses invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs onto film.
Magnetic resonance imaging (MRI). A diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body; can often determine damage or disease in a surrounding ligament or muscle.
Arthroscopy. A minimally-invasive diagnostic and treatment procedure used for conditions of a joint. This procedure uses a small, lighted, optic tube (arthroscope) that is inserted into the joint through a small incision in the joint. Images of the inside of the joint are projected onto a screen; used to evaluate any degenerative and/or arthritic changes in the joint; to detect bone diseases and tumors; to determine the cause of bone pain and inflammation.
Specific treatment for a torn meniscus will be determined by your doctor based on:
Your overall health and medical history
How bad your injury is
How well you can tolerate specific medications, procedures, and therapies
The length of time it will take to heal
Your opinion or preference
Treatment may include:
Medication, such as ibuprofen
