The Knee Joint

The knee is amongst the most complex and largest joints in the human body. It is very significant in movement. The thighbone is connected to the lower leg bones by ligaments that play a vital role of stabilizing the knee joint. In sports it is very common to get cases of knee ligament tears or strains.

Multiple injuries on knee ligament used to result in the end of an athlete's career. However, modern medicine now allows for multiple ligament injuries to be treated and enable an athlete to return to sporting activities.

Anatomy of Knee Joint

Knee Joint & Ligament AnatomyThe knee joint is formed by three bones: femur or thigh bone, shinbone or tibia and patella or kneecap. The kneecap is found in front of the joint to provide some protection. Ligaments connect one bone to another. The knee has four primary ligaments that keep it stable. In addition, the ligaments hold the knee bonds together by acting like strong bands.

Collateral Ligaments

They are located on the sides of your knee. The LCL-lateral collateral ligament is located on the outside while the MCL-medial collateral ligament is on the inside. Collateral ligaments manage sideways movement of the knee. It also supports it against unusual movement.

Cruciate Ligaments

They are located on the sides of the knee. The ACL (anterior cruciate ligament) and PCL (posterior cruciate ligament) cross each other to form an "X". The ACL is found at the front while the PCL is found at the back. These ligaments are tasked with controlling backward and forward movement of your knee.

Knee Ligament Injuries

The knee joint is prone to injuries due to the fact that it relies solely on the adjacent muscles and ligaments for stability. You can sustain a knee ligament injury through hard muscle contraction like rapid change of direction while running. Moreover, direct knee contact can also result into ligament injuries. It is also possible for you to have multiple knee ligament injuries at the same time.

Multiple knee ligament injuries can cause severe problems like disruption of nerves in leg muscles and interruption of blood supply to the limbs. In severe instances, amputation may be needed. High velocity trauma is the main cause of multiple knee ligament injuries. It can be as a result of skiing, falling from heights and traffic accidents.

Compared to the MCL, the LCL is the less likely to be injured. However, a LCL injury will result in injuries to other parts of the joint due to complexity of the anatomy of the outside knee.

Knee Ligament Injuries Treatment

People with suspected multiple knee ligament injuries need to consult an experienced orthopaedic surgeon for examination. The surgeon may enlist the services of a microsurgeon or vascular surgeon depending on the injury. The surgery conducted depends on the number of injured ligaments. It may be a 2-stage surgery or single stage surgery. If both the MCL and the ACL are torn or injured, the surgeon will reconstruct them through a single surgery.
