Collateral ligaments are located on either side of the knee and attached to the thigh and the leg.
There are two strong collateral ligaments – Medial collateral ligament (MCL) and lateral collateral ligament (LCL). They help prevent excessive movement of the knee.
Injuries to MCL are more common and it is likely to occur by any of the following ways:
Falling off with a bent knee in a knock-kneed position so that the knee is pushed inwardly and lower leg outwardly.
Being stuck on the outside of the knee as in tackle Injuries to LCL are less common and more complicated.
They are a result of direct trauma that can cause damage to a number of other tendons and ligaments.
LCL injuries may occur when:
Inside of the knee is hurt forcing it to move outwards in a bow-legged position.
A direct blow to the front of the knee.
