A lateral collateral ligament (LCL) injury is usually caused by your knee being pushed outwards (away from your other knee). This may happen if you have a blow to the inside of your leg, which can happen during contact sports such as football.

This refers to pain in the front of the knee behind, or around, the knee cap also called patellofemoral pain syndrome.

ACL sprain or rupture happens to the large thick ligament in the centre of the knee. It commonly happens in contact sports when the foot is planted and the body rotates under force causing a twisting of the knee.

This is an incredibly common injury to the two C-shaped discs of cartilage inside the knee. Read more about to identify a meniscus tear, the causes, symptoms and exercises to help improve knee function.
