What is an ACL Injury?

download (2)An ACL injury  happens when there is a tear of the anterior cruciate ligament (ACL), this is one of the primary ligaments in the knee. ACL injuries are most common in a sport that requires you stop suddenly. This could be jumping, foot but, tennis, gymnastics, football, downhill, volleyball.

Many people say they hear or feel at the time that the ACL injury occur. The knee may begin to swell feel wobbly and unstable; then it will become too painful to carry weight.

Depending on how severe your ACL injury, treatment may include and rehabilitation exercise to help you regain strength and stability or energy or surgery to replace the torn ligament accompanied by recovery. A proper training program may help decrease the risk of an ACL injury.

Anterior Cruciate Ligament (ACL)Symptoms and Causes of an ACL Injury

The signs and symptoms of an ACL injury can include the following:

  • A loud “pop” or “popping” sensation in the knee
  • Severe pain and an inability to continue activity
  • Swelling that begins within a few hours of the injury.
  • Lost of range of motion
  • A feeling or instability and the inability to carry any weight on you knee.

Once you have any of these symptoms, you should see a doctor immediately. The knee joint is one of the most complex bone structures in the body, consisting of bones, tendons, ligaments, and other tissues that work to provide movement and provide strength and stability to the leg. It’s important to get a quick and accurate diagnosis from the doctor to determine, the amount of severity for injury to get proper treatment.

ACL_Injury1Causes of a torn ACL

Ligaments are tough cords of tissue that joins one bone to another, The ACL, one of two ligaments that intersect in the middle of the knee, connects your thighbone (femur) to the shinbone or tibia and helps stabilize the knee joint.

  • Most ACL injuries happens during a fitness or sports activity that can place stress on knee:
  • Slowing down sliding and changing direction (cutting)
  • Pivoting direction with your foot firmly planted on the floor
  • Stopping suddenly
  • Receiving a direct collision or blow to the knee, such as a football tackle,
  • Receiving a collision or direct strike to the knee, like a football tackle
  • Landing from a jump incorrectly.

Once the a ligament is damaged, there is normally a partial or complete tear through the tissue. A mild injury may stress over overstretch the ligament but leave it intact.

What are the Risk Factors for Developing an ACL injury?

Women are more prone to have an ACL injury than men who engage in the same sports. Research has indicated some reason for the differences in risk.

Women athlete tend to exhibit strength a strength imbalance in the thighs with the muscle at the front of the thigh or quadriceps, being stronger than muscles at the back (hamstrings) The hamstring helps prevent the shinbone from moving too far forward moving the can overextend the ACL.

In research comparing jumping and landing for men and women athletes, women tend to be more prone to land from a jump in a way that will increase the stress on their knees.

These studies suggest that trying to strengthen muscles of the large and lower techniques, as well as training to improve your jumping and landing techniques, may help to reduce the higher ACL injury risk for women.

People who have an ACL injury are at higher risk of developing knee osteoarthritis, in which the joint cartilage deteriorates as well the smooth surface roughens. Arthritis may occur even after a person has had surgery to reconstruct the ligament.

Multiple factors can include the risk of arthritis, such as the seriousness of the original injury, the appearance of related injuries in the knee joint or the level of active after treatment.

Diagnosis of ACL injury

The doctor will ask to check your knee for swelling and tenderness; he would compare your injured knee to your uninjured knee. He or she may also move your knee into various positions to evaluate the range of motion and overall function of the joint.

Your diagnosis can be made by the physical seam alone, but you may need to have other tests to rule out any other causes to determine the serious of the injury. These test may include:

X-rays may be needed rule out a bone fracture. X-rays can not value soft tissues, such as tendons and ligaments.

An MRI 0 magnetic resonance imaging, An MRI use radio waves and a strong magnetic field to develop an image of broth hard and soft tissues in your boy. An MRI can show the extent of anACL injury and signs of damage of there tissues in the knee.

Ultrasound – This uses sound waves to visualize internal structures, ultrasound may be used to check for injuries in the ligaments, muscles tendons of the knee.

ACL Injury Treatment

The first thing you will need to do is get first-aid care to decrease pain, and swelling ideally after injury your knee. RICE model of self-acre at home:

Rest- get rest necessary for healing and limits weight stress on the knee.

Ice – when you’re awake, try to ice your knee at least every two hours for 20 minutes at time

Elevation is important – Lie down with your knee propped up on pillows

Compression Warp an elastic bandage or compression wrap around your knee.


Medical treatment for An ACL injury should start with serval week fo rehabilitative therapy. A physical therapist will teach you how to do exercise that will perform either with continued supervision or at home. You can also wear a brace to stabilize the knee and use crutches for a some time to avoid putting weight on your knee.

The priority of rehabilitation is toe reduced pain and swelling, restore your knee’s full range of motion, and strengthen muscles. This course of physical therapy may say successfully treat an ACL injury of people who are mostly inactive, engaging in moderate exercise and recreational activities, or perhaps play sports that put less stress on the knees

Anterior Cruciate Ligament (ACL) Surgery

Surgery for anterior cruciate ligament involves repairing or reconstructing the ACL.

Your doctor may recommend surgery if:

You are an athlete and would like to continue in the sport, specifically, if the sport consists of cutting, jumping or pivoting.
You are younger age and active
The ACL injury is causing the knee to buckle during everyday activities
More than on ligament of the cartilage in your knee is injured.

During ACL recon Sur icon, the surgeon, removes the damaged ligament and ligament and replaces it with a segment of the tendon – tissue similar to a ligament that attaches muscle to bone. Thos replacement tissues are called a graft. Your surgeon will utilize a part of the tendon from another area of the knee or a deceased donor for muscle tendon. The graft will be used as scaffolding on which the alignment tissue can grow.

After the surgery, the person will resume another stage of rehabilitative therapy. After successful reconstruction energy and rigorous rehabilitation, you can get restored stability and function to the knee, after can return to their sport after eight to 12 months.
