What Causes Pain In The Knees?

Sprained Ligaments

Ligaments connect two bones together, and sprained ligaments may develop after an injury or accident. The knee is supported by four main ligaments: the anterior cruciate ligament, posterior cruciate ligament, medial collateral ligament, and lateral collateral ligament. In addition to these ligaments, many smaller ligaments are also routinely injured. Individuals who have sprained ligaments could experience swelling, pain, stiffness, and instability or buckling of the knee. Sports injuries, falls, and car accidents are common causes of this type of injury. If imaging studies confirm the presence of one or more sprained ligaments, treatment will be tailored to the specific ligament that is injured. Some types of ligament sprains may respond well to bracing, physical therapy, and other conservative treatments, and more serious sprains may need surgery.
