The anterior cruciate ligament is a ligament that is inside the knee joint, is one of the ligaments responsible for giving stability to the knee. Its main function is to prevent the leg from moving forward with respect to the thigh. This ligament is anchored on one side to the femur and on the other to the tibia. The rupture of this ligament may be partial or complete; depending on the degree of rupture, the existence of ruptures of other ligaments of the knee and the muscular power of the patient may give symptoms of greater or lesser intensity.
In most cases it is due to a sports injury, they are especially frequent in impact sports in which the knees are overloaded with sudden changes of direction or jumping: football, skiing, basketball, etc.
At the time of rupture intense pain occurs in the knee accompanied by inflammation due to the accumulation of blood inside the knee, due to pain and inflammation is difficult to mobilize the knee. After recovering from the acute injury, the patient may notice instability (it is the feeling that the knee bends and gives in abruptly involuntarily, as if the knee «goes away»). Sometimes people with this broken ligament may have pain and swelling of the knee after a sports activity.
At the time of rupture when there is significant inflammation of the knee is usually evacuate the blood inside the knee using a syringe (arthrocentesis), this will relieve pain. Immobilization, which should not exceed 3 weeks, together with the use of anti-inflammatories will relieve symptoms.
After immobilization, whether you decide on surgery or not, it is advisable to perform controlled rehabilitation exercises to restore movement and strengthen the muscles of the thigh and leg. The decision to reconstruct the ligament by surgery will be made depending on multiple factors: degree of injury, symptoms that derive from the injury, sports activity, etc. … The surgery consists of removing the remains of the damaged ligament and putting a new ligament that is constructed from tendons usually removed from other points of the injured knee; There is also the possibility of using tendons extracted from the corpse.
