Background[ edit ] The Anterior Cruciate Ligament is the ligament that keeps the knee stable. ACL injuries can be categorized into groups- contact and non-contact based on the nature of the injury  Contact injuries occur when a person or object come into contact with the knee causing the ligament to tear.
Treatment for ACL injuries in children requires special consideration because of the location of growth plates. ACL injuries are classified by grades 1, 2, and 3. What is the anterior cruciate ligament?
The knee is a hinge joint held together by four ligaments. A ligament is a structure in the knee that holds the bones together and helps to control joint movement or motion. There is a ligament on each side of the knee the collateral ligaments and two ligaments deep inside the knee.
Both ligaments attach on one side to the end of the thighbone femur and on the other to the top of the shinbone tibia.
During activity, the ACL controls how far forward the tibia can "slide" relative to the femur: While some degree of motion or sliding is normal and is required for knee function, too much motion may damage other structures in the knee which can lead to long term problems in some patients.
How is the ACL injured? What are the symptoms? The ACL can be injured or torn in a number of different ways. The most common mechanism is that of a sudden pivoting or cutting maneuver during sporting activity, which is commonly seen in football, basketball and soccer. The ligament can also tear due to work injuries or automobile accidents.
The amount of pain experienced at the time of the injury is somewhat variable but can be quite severe. Typically, the person is unable to continue play or activity, and has the impression that a significant injury has occurred.
Immediate swelling of the knee develops at the time of injury—within the first several hours—but the extent of swelling can be limited if the knee is immediately iced or splinted.
What are the symptoms of an ACL injury or tear? How is an ACL injury diagnosed? An ACL tear can be diagnosed by a physician through a history and physical examination.
On physical examination, the physician can specifically assess the amount of motion present and determine if the ACL is torn.
Additionally, evaluation of other structures within the knee is done also, as ACL tears are often found in association with injury to other structures within the knee, such as the cartilage and collateral ligaments.
X-rays are taken to evaluate for the presence of any fractures. In many patients, an MRI scan of the knee may be ordered.
The scan can clarify the question of an ACL tear if the history and examination are inconclusive.
The scan is also useful for evaluating the cartilage or meniscus tissue in the knee if this information is necessary to make decisions regarding the best treatment for a specific patient.An ACL sprain is a tear to the anterior cruciate ligament in the knee which runs diagonally from the back of the femur (thigh bone) upwards and forwards to the front of the tibia (shin bone) and prevents the shin bone from moving excessively forward.
Deadlifts come in all shapes and sizes and can be used for a variety of training goals. This guide is going to break down the movement in-depth, teach you how to optimize your deadlift technique, and teach you how to start maximizing your deadlift training. The anterior cruciate ligament (ACL) is one of four ligaments that help stabilize the knee.
It is the most commonly injured knee ligament. ACL injury usually occurs when the knee is hyperextended (straightened) and a pivot occurs simultaneously. Prevention of Anterior Cruciate Ligament Injury Darin A.
Padua, PhD, ATC*; Lindsay J. Most ACL injuries do not involve a direct blow to the knee15–17 but rather are noncontact or indirect contact in nature, involving uncontrolled lower extremity biomechan-ics.
Thus, ACL injury prevention may be achieved by. SUMMARY OF RECOMMENDATIONS The following is a summary of the recommendations of the AAOS clinical practice guideline on the Management of Anterior Cruciate Ligament Injuries.
A nurse provides postoperative instructions to a patient who underwent reconstructive surgery for an anterior crucial ligament (ACL) injury. Which statement made by the patient indicates the need for further teaching?
