Knee
Torn Ligaments - ACL and MCL
Your knee is a mobile joint that is stabilized by four main ligaments. The two most common ligament injuries are to the anterior cruciate ligament (ACL) found in the center of your knee, and the medial collateral ligament (MCL) located on the inside of your knee.
An ACL injury is generally caused when the foot is planted on the ground and the knee is suddenly twisted, as with a skiing accident. Injuries to the ACL and the MCL are also common among individuals who participate in contact sports such as soccer and football, where impact can occur to the side of the knee.
An injury to any of your ligaments can cause pain or weakness in your knee joint. Therefore, immediate and proper treatment can help you return to an active lifestyle and help prevent future problems with your knee. Your orthopedic physician will determine the best course of action based on the severity of your injury.
Other Common Causes of Knee Pain - Meniscus Tears and Osteoarthritis
A torn meniscus can also cause knee pain. The meniscus is another term for the cartilage inside the knee. It absorbs and distributes the forces of the body’s own weight and physical activities such as running and walking.
Meniscus tears often require surgical repair and physical therapy as they may not heal on their own. Without surgical repair, tears in the meniscus cartilage may continue to cause pain, irritation, swelling and a catching sensation.
However, it is important to remember that knee pain is not always associated with sudden injury. Pain can also arise from the breakdown of knee cartilage associated with aging and normal wear and tear of the knee joint. It is a condition called osteoarthritis, it can lead to pain, stiffness and even disability.
If you are experiencing knee pain or believe you have injured your knee then you should speak with an orthopedic physician who can determine the best course of medical treatment.
