Crossed, anterior and posterior cruciate ligaments are located in the knee and help to guide the movement of the joint. Specifically, the anterior cruciate ligament (ACL) is the main obstacle to previous translation of the tibia and also limits its ability to rotate internally.


What kind of injuries can suffer ACL?

Although the LCA may be damaged as a result of trauma, injuries usually occur without physical contact, when an individual race brakes suddenly, when a rotation of the body with the fixed foot on the ground or reception comes a jump knee misplacement. These injuries occur most often in athletes than in the general population, especially in females.

In the last decade it has been shown to prevent certain movements and gestures and specific training to increase neuromuscular coordination can significantly reduce the number of injuries.


If torn ligament, should always be used when surgery?

Conservative treatment, nonoperative therapy involves physical, functional recovery followed by joint. In some weeks you can restore mobility and function of the joint pain, especially when there are no associated lesions. However, many patients who choose to undergo this treatment over time new episodes of instability and sometimes suffer other injuries (typically menisci) leading the patient to consult again the specialist in traumatology .

Surgical treatment is recommended input to athletes and patients with physically demanding, they perceive his knee is unstable or have associated lesions.

Surgical techniques to repair the anterior cruciate ligament

LCA breaks are not usually repaired by suturing since this treatment has shown in the past a high failure rate. The usual surgical treatment is to replace the injured ligament by a tendon graft, taken from the patient or donor.

The technique is used to perform arthroscopically and is drilled bone tunnels in the insertion sites of the original ligament in the femur and tibia, and placing the graft so that faithfully reproduces the anatomy of the native ACL.


How long the rehabilitation of anterior cruciate ligament?

The rehabilitation process consists of several phases, aimed at reducing postoperative inflammation, recover mobility of the joint, the strength of the muscles that control and responsiveness. In addition, the graft undergoes a process of integration and progressive remodeling that usually lasts more than six months. Therefore, although a disciplined patient with the rehabilitation process can feel good relatively soon, the ligament will not have reached sufficient strength until it has fulfilled this time.

In patients younger than 20 years because of the high rate of ACL rerupturas intervened to have found, it is recommended to take special care with the rehabilitation process and prolong the period of return to sport.
