The knee is a complex joint which consists of bone, cartilage, ligaments and tendons that make joint movements easy and at the same time more susceptible to various kinds of injuries.
Anterior Cruciate Ligament (ACL) Tears
The anterior cruciate ligament, or ACL, is one of the major ligaments of the knee that is located in the middle of the knee and runs from the femur (thigh bone) to the tibia (shin bone). It prevents the tibia from sliding out in front of the femur. Together with posterior cruciate ligament (PCL) it provides rotational stability to the knee.
The medial collateral ligament (MCL), a band of tissue present on the inside of your knee joint, connects your thigh bone and shin bone (bone of your lower leg). The MCL maintains the integrity of the knee joint and prevents it from bending inward.
Knee sprain is a common injury that occurs from overstretching of the ligaments that support the knee joint. A knee sprain occurs when the knee ligaments are twisted or turned beyond its normal range causing the ligaments to tear.
Posterior Cruciate Ligament Injuries
Posterior cruciate ligament (PCL), one of four major ligaments of the knee is situated at the back of the knee. It connects the thighbone (femur) to the shinbone (tibia). The PCL limits the backward motion of the shinbone.
The knee is a complex joint of the body which is vital for movement. The four major ligaments of the knee are anterior cruciate ligament, posterior cruciate ligament, medial collateral ligament and lateral collateral ligament. They play an important role in maintaining the stability of the knee.
Ligaments are the fibrous tissue brands connecting the bones in the joint and stabilizing the joint. Knee joint has 2 sets of ligaments–collateral ligaments (medial and collateral ligaments) that connect the bones on outer side of the knee and cruciate ligaments (anterior cruciate ligament and posterior cruciate ligament) those present inside the joint. Multi-ligament injury is the injury to multiple ligaments at the same time. Damage to three or more ligaments may cause joint dislocation.
Medial Collateral Ligament Tear in Adults
The medial collateral ligament (MCL) is the ligament that is located on the inner part of the knee joint. It runs from the femur (thighbone) to the top of the tibia (shinbone) and helps in stabilizing the knee. Medial collateral ligament (MCL) injury can result in a stretch, partial tear, or complete tear of the ligament. Injuries to the MCL commonly occur as a result of a pressure or stress on the outside part of the knee. Anterior cruciate ligament (ACL) may be torn along with a MCL injury.
