Knee Sports Injuries
Anterior Cruciate Ligament (ACL) Tear, Medial Collateral Ligament (MCL) Injury, PCL Tear, LCL Tear.
Overview
There are four primary ligaments in the knee, all responsible for its seamless movement. Ligaments are sturdy connective tissue bands that attach bones together and reinforce the joint’s stability and strength. The four primary ligaments of the knee include the following:
- The anterior cruciate ligament (ACL), a critical ligament located in the middle of the knee, plays a crucial role in the forward motion of the tibia and the control of its rotation. Its significance in knee function cannot be overstated.
- The posterior cruciate ligament (PCL), situated at the back of the knee, is a key player in the control of the backward motion of the shin bone. Its role in maintaining knee stability is of utmost importance.
- The medial collateral ligament (MCL), an indispensable ligament, is responsible for stabilizing the inner knee. Its role in providing crucial knee support cannot be overlooked.
- The lateral collateral ligament (LCL) is a crucial ligament that stabilises the outer knee.
Causes of Cruciate Ligament Injuries
One of the most widely injured knee ligaments is the anterior cruciate ligament (ACL), which may be overly stretched and torn due to excessive knee twisting. Playing certain sports, such as soccer, football, and basketball, increases one's risk of knee ligament injuries.
Another ligament commonly susceptible to injury includes the posterior cruciate ligament (PCL) due to unexpected, direct impact to the knee from a traumatic motor vehicle accident or football attack.
Causes of Collateral Ligament Injuries
The medial collateral ligament is the most widely injured compared to the lateral collateral ligament. Tears to these ligaments are often caused by traumatic sports injuries, such as sudden, direct impact to the outer part of the knee.
Symptoms of Collateral Ligament Injuries
The knee may buckle or pop, resulting in joint swelling and pain. It’s crucial to consult with your doctor to confirm a diagnosis, as they can provide the best guidance and reassurance.
Symptoms of Cruciate Ligament Injuries
Directly after the injury, you may notice a popping sound near the area, and your leg may buckle, making it difficult to stand or place pressure on it. It's important to take immediate action and seek medical attention.
