Information About Knee Ligament Injuries

Find information about ligament injuries of the knee. These include anterior cruciate ligament injuries (ACL), posterior cruciate ligament injuries (PCL), and medial collateral ligament injuries (MCL). Included is information on how these injuries occur and what treatments are available.
Medial Collateral Ligament (MCL) Injury
The medial collateral ligament (or MCL) is one of four ligaments that acts to stabilize the knee joint. The medial collateral ligament may be injured in isolation, or in combination with the meniscus and other ligaments within the knee joint.
Posterior Cruciate Ligament (PCL) Injury
Injury to the posterior cruciate ligament, or PCL, is an uncommon knee injury. When the PCL is injured, patients may have problems with knee instability. Treatment of PCL tears is controversial, but PCL reconstruction surgery is an option.
Knee Braces
Knee braces are used in the treatment and prevention of many common knee injuries. A knee brace is designed to control knee motion. The knee brace either substitutes the function of a normal knee ligament, or helps to protect a knee ligament.
Pellegrini-Stieda Syndrome
Pellegrini-Stieda syndrome is a condition of pain at the insertion of the medial collateral ligament on the thigh bone. Pellegrini-Stieda syndrome and the Pellegrini-Stieda sign are seen in patients who have had a medial collateral ligament injury.
