Introduction

The anterior cruciate ligament is a ligament in the centre of the knee. It is attached on one side to the femur, the other to the tibia. It is very solid. Its role is essential in the rotation of the knee. Its role is to maintain against each other, the tibia and femur during the twisting of the knee. It can break at a significant twisting, which exceeds its capacity. It is a severe sprain. The movements of everyday life do not require the anterior cruciate ligament. It occurs during movement of pivotal rotation of the body from the foot gets stuck (Ireland 1999, 150).Discussion

'Unhappy triad' injuries and risk factor

The most common injury to the medial collateral ligament (40% of cases) is avulsion from its tibial attachment, followed equally by tears at its midpoint and its proximal portion. Much less frequent are injuries at the ligament's femoral attachment given the strength of this attachment and the firm connections the ligament has at this point with the thigh Apo neurosis, which is also attached to the epicondyle; in the event of an avulsion, there is a displacement of the bony structures. In distal tears, which can affect the whole of the attachment, the ligament appears warped, retracted and edematous.

The following three injury types are commonly found in the ACL in decreasing order of importance: l. a complete tear (usually of the superior attachment); 2.a partial tear (with concomitant fraying of a few strands and ligament insufficiency); 3.a avulsion at the tibial spine with bone migration. Posterior cruciate ligament lesions are rare. In normal patients seek medical care several hours after sustaining their injury. It is then more challenging to examine them since they often present with a more or less intense synovial reaction. Such a reaction does not unmistakably indicate the presence of an intra-articular lesion, since it only occurs in about half of all cases and, when an injury exists, its intensity is sometimes unrelated to the severity of the injury. An effusion may be completely absent because the tear may be extra-articular or because the fluid has escaped its original site through the capsule, diffusing into the neighbouring tissues; in some cases, patients develop ecchymosed that can reach up to the ankle (Kirkendall 2000, 64).

Edema is on the lateral side of the knee. It is normally located in the area occupied by the ligaments, as well as ecchymosed in the region of the pesanserinus or of the fibular head, is some of the most frequent findings, the intensity of the oedema reaction being greatest in the outermost area. Mobility is substantially impaired because of the contracture and the pain. Under pressure, pain is felt all along the ligament; the pain increases sharply at the rupture site. The Moraga's manoeuvre can prove useful for the exploration of the ligament (placing the ankle of the involved leg at the healthy knee, a forceful adduction is carried out by exerting a downward pressure on the joint. Under examination since it makes it possible to feel the ligament strands as they become taut thereby identifying discontinuities or ...
