Anterior Cruciate Ligament

Anterior cruciate ligament injury

Introduction

Anterior cruciate ligament (ACL) is one of the most traumatized ligaments of the knee joint. Among the other entire knee ligament anterior cruciate injured more often, such as anterior cruciate ligament ruptures occur 15-30 times more frequently than the posterior cruciate ligament ruptures. The mechanism of injury ACL is most often associated with sports and often lies in valgus bending leg and pronation. To determine the anterior cruciate ligament rupture physician diagnoses, most of which is indicative of MRI. Anterior cruciate ligament injury is the knee injury which is cause mainly due to the sport activities. These types of injuries are found in people who are usually involved in sports such as basketball; football, volleyball and tennis are considerably more prostrate to ACL injuries.

Discussion

The ACL connects the back-side of the femur to the front-half of the tibia, passing behind the kneecap. This union can prevent a forward displacement of the tibia on the femur, while the posterior cruciate ligament (PCL) prevents backward displacement of the tibia on the femur, both combined provides rotational stability to the knee. The ruptures of this ligament are common to aggressive physical activity, especially when impacts occur causing knock-knees forced the leg, requiring surgery for their reconstruction. This may be by arthroscopy or open surgery. For the new ligament, tissue can be used an auto-graft or allograft. However, the operation is not necessary to some patients performing little physical activity, who can lead a normal life without this ligament after muscle strengthening rehabilitation. The Lachman test or drawer test (and possibly other tests associated with clinical or radiographic) detect an ACL tear (Frank and Jackson, 1997).

Symptoms

Damage in the anterior cruciate ligament injury is usually preceded by the knee, after which there is pain and swelling of the knee strong. ...
