Meniscus and Articular Cartilage Tears

Written by kneepaincure.com   

Meniscus and Articular Cartilage Tears are extremely common. Younger people have tough and rubbery meniscus. Tears occur most frequently as a result of forceful twisting trauma. Older people experience a weakening meniscus, making them susceptible to injury even from simple squatting or negotiating stairs. Younger people have tough and rubbery meniscus. Tears occur most frequently as a result of forceful twisting trauma. 

To repeat, the meniscus acts like a gasket between the femur above and the tibia below. The meniscus fills in the space between the round femur and the flat tibia. The meniscus acts like a gasket, helping to distribute the weight from the femur to the tibia. Without the meniscus, any weight from the femur would be concentrated on one spot on the tibia. Now the weight is distributed which also serves to protect the articular cartilage.

The meniscus can be torn in several ways. The entire inner rim of the medial meniscus can be torn. Also, there can be a flap torn from the inner rim, or the tear can be degenerative where a portion of the meniscus is frayed and torn in multiple directions.

The symptoms are pain along the joint line, and locking as the leg is extended and pulled back. In effect, the leg catches in the hinge mechanism of the joint. The leg can not straighten or be fully bent.

Constant rubbing of the torn meniscus against the articular cartilage can cause deterioration on the surface, leading to degeneration of the joint and possible arthritis. These tears can give rise to synovial fluid which can make the knee stiff and swollen.

X-rays do not uncover tears, while the MRI shows clearly the presence of damage. Generally, if the obvious symptoms exist, arthroscopy can confirm the diagnosis and extract the torn pieces in the same procedure. After the injury, it is important to ice the knee to reduce any swelling and mitigate pain. If the knee is locked, surgery may be required to repair the tear. Degenerative tears in older people are usually not repairable. After surgery, rehab should commence immediately, particularly to build up the quadracep muscle through leg extensions.
