ACL Injuries: Causes, Symptoms, Treatment, and Recovery

ACL Injuries: Causes, Symptoms, Treatment, and Recovery

Introduction

An ACL injury is one of the most common knee injuries, which is more common among athletes. ACL injury happens in the anterior cruciate ligament (ACL). It is an important ligament in the knee joint, which gives stability to the knee and makes it easy to rotate it. ACL injuries can range from minor sprains to complete tears. They often occur during activities in which you suddenly change direction, jump, or there is a direct impact on the knee. ACL injury can have significant effect. While common people may find it difficult to do everyday activities with easy, it may disrupt an athlete’s training and performance. Long-term effects include difficulty moving around and reduced quality of life.

Some sportspersons are more likely to get ACL injuries. These include soccer, basketball, football, and skiing, where your knee undergoes high-intensity movements. For individuals suffering from an ACL tear, proper diagnosis, treatment, and recovery steps are important to return to the normal routine. In this blog, we will explore the causes, symptoms, treatment options, and recovery time needed for ACL injuries. We will also tell you some preventive tips that can help you in the future.

What is an ACL Injury?

The anterior cruciate ligament (ACL) is an important ligament that gives stability to your knee. It reduces the chances of your tibia (shinbone) sliding forward during activities. It also gives rotational stability to the knee. An ACL injury can reduce your ability to walk, run, and do everyday tasks. They usually happen when a ligament is overstretched or torn due to sudden movements, like twisting, pivoting, or landing awkwardly on the ground after a jump. People who play high-impact sports are more prone to these injuries. Sometimes these injuries can also be caused by accidents or falls.

Common Causes of ACL Tears

ACL tears are most commonly caused by:

  • Excessive strain during sports: High-impact sports like soccer, basketball, and skiing put excessive strain on the knee, increasing the risk of injury.
  • Sudden Movements: Twisting or pivoting the knee in quick movements can overstretch the ACL and tear it.
  • Accidents: Unexpected falls or accidents can put undue pressure on the knee joint, damaging your ACL.
  • Improper Landing: Landing awkwardly after a jump can put too much force on your knee joint, resulting in an ACL tear.

Symptoms of an ACL Injury

It is very easy to identify an ACL injury. Given below are the common ACL injury symptoms:

  • Knee Pain: Sharp pain, often accompanied by a popping sound during the injury.
  • Swelling: Swelling may occur within hours of the injury, leading to stiffness in the knee.
  • Instability: Your injured knee may feel unstable. You may also feel that it is giving way during movement. 
  • Loss of Range of Motion: You might find it difficult to move your injured knee. This can happen because of pain and swelling.
  • Tenderness: Your knee might be sensitive to touch due to pain, at the site of ACL injury.

Diagnosis of ACL Injuries

Doctors detect ACL injuries after examining the knee in-person and doing some tests. Let us discuss some common steps for diagnosis: 

  • Physical Examination: The doctor will check if there is instability in your knee. They may compare your injured knee with the non-injured one.
  • Imaging Tests: An MRI scan is often used to get a detailed view of soft tissue injuries, including ACL tears. While X-rays cannot show ACL tears, they may be used to rule out bone fractures.

Treatment Options for ACL Tears

Treatment for ACL injuries depends on the severity of the tear and the patient’s activity level. Options include:

  • Non-Surgical Treatment: For individuals with lower activity levels, physical therapy, rest, and knee bracing may give relief and improve movement.
  • ACL Surgery: In cases of complete ACL tears, surgery may be required. ACL surgery typically involves reconstructing the torn ligament using tissue from the patient or a donor.
  • Rehabilitation: Post-surgery rehabilitation is critical to regaining full knee function. This includes physical therapy, strength training, and flexibility exercises.

Recovery and Rehabilitation Post-ACL Surgery

Recovery from ACL surgery can be a lengthy process, typically taking between 6 to 12 months. During this time, rehabilitation exercises are essential to restore knee function and strength. Key aspects of recovery include:

  • Physical Therapy: Strengthening exercises and mobility drills help improve flexibility and muscle support around the knee.
  • Bracing: Using a knee brace during rehabilitation can offer extra support as the ACL heals.
  • Activity Gradually Resumed: As healing progresses, low-impact activities like swimming or cycling may be reintroduced before returning to high-intensity sports.

Preventing ACL Injuries: Tips for Athletes

Preventing ACL injuries is possible with proactive measures such as:

  • Strengthening Exercises: Focus on exercises that improve strength in the quadriceps, hamstrings, and calf muscles to stabilize the knee.
  • Proper Technique: Athletes should be taught how to land correctly from jumps, avoid sudden pivots, and use proper body mechanics during sports.
  • Flexibility Training: Maintaining flexibility in the muscles surrounding the knee joint reduces the risk of overstretching the ACL.
  • Neuromuscular Training: Training to improve balance, agility, and control can reduce the risk of ACL injuries.
