Torn knee ligament
Causes:
Torn knee ligament occurs when at least one of the main ligaments inside the knee gets sprained and the condition gets to harsher so the ligament ruptures. Basically, there are four main ligaments; Medial collateral ligament(MCL), Lateral collateral ligament(LCL), Anterior cruciate ligament(ACL) and Posterior cruciate ligament(PCL). All these ligaments have different functions.
- MCL is located between femur and tibia. It helps protect the knee joint from the outer side forces, and it controls the amount of movement of knee. For the MCL injury, it happens mostly during the sports, especially in soccer and in rugby when the players have to tackle each other. When they tackle, their legs are stretched and the outer

- ACL is located inside the knee joint. It connects anterior tibia and posterior femur diagonally. It controls the backward and forward movements of the knee. Also, it regulates the tibia bone from moving in front of the femur. ACL injury usually happens when the people suddenly twist their knee in the opposite way after they jump and land. So, volleyball and basketball players are most likely to have this injury. Also, when the patient has ACL injury, most of them also has other injuries in different ligaments.
- And, PCL located inside the knee joint. It connects posterior tibia and anterior femur diagonally. It controls the backward and forward movements of the knee. ACL and PCL are diagonal to each other so they also known as cross ligaments. PCL injury is not a common knee injury since PCL is more secure than ACL. PCL injury mostly happens when the patients have car accidents in the situations where the knee hits a part in the car.
