It is the ligaments which connect one bone to another. The ligaments which are outside your knee joint are known as the medial collateral ligament as well as the lateral collateral ligament. These provide your knee with stability as well as limit the amount that it can move from side to side. The medial collateral ligament is found on the inner side of your knee. It is taut when your leg is straight. Even though it’s a strong ligament but it can be sprained or completely ruptured. Such knee ligament injury happens in case you twist your straightened leg or are knocked sideways.
The lateral collateral ligament is similar to a thin, strong cord which runs on the outer side of your knee. Knee ligament injury may be classified as grade 1 in case it is a sprain with no tearing of the ligament. Besides, grade 2 refers to a partial tear of the ligament while grade 3 is due to a complete tear of the ligament.
The ligaments inside your knee joint provide stability to your knee, when it is in various positions. The other knee ligament injury refers to the soft tissues around your knee, which can also be injured. Soft tissue refers to any tissue in your body which isn’t a bone.
In case you play a sport which involves twisting your upper leg while you have your foot planted on the floor, you may tend to tear the cartilage in your knee. This cartilage may become worn down as you get older, which makes it easier to tear even after a minor injury. Overuse of your knee can also result in knee ligament injury as you may tear a patellar tendon, which connects your kneecap to your thigh muscle. The symptoms for most ligament injuries tend to be similar, no matter which has been damaged.
