What is an ACL Tear?

An ACL tear is an injury to the anterior cruciate ligament (ACL) in your knee. The ACL acts like a strong, flexible band that stabilizes your knee during movement. When it tears, it can cause pain and make activities like running and jumping difficult.

How Does it Happen?

ACL tears often occur when the knee twists too much or receives a hard impact. This injury is common in sports such as soccer, basketball, and football, but it can also happen during everyday activities. Many people hear a “pop” when the ACL tears, which is a sign that something is wrong.

How to Tell if You Have an ACL Tear

Common signs and symptoms include:

  • Pain: Especially when walking or putting weight on the knee.
  • Swelling: The knee may look swollen and larger than usual.
  • Weakness: The leg might feel weak or difficult to move.
  • Instability: A sensation that the knee is wobbly or giving way when standing or walking.

What Causes an ACL Tear?

ACL tears can result from:

  • Sports Injuries: Sudden stops, quick direction changes, or collisions during sports.
  • Awkward Landings: Landing improperly from a jump or pivoting with the foot planted.
  • Car Accidents: Impact on the knee can sometimes cause an ACL tear.

Types of ACL Tears

  • Partial Tear: Only part of the ACL is damaged.
  • Complete Tear: The entire ACL is torn into two parts, usually requiring more intensive treatment.

How Can an ACL Tear Be Treated?

Treatment depends on severity, age, and activity level:

  • Rest and Physical Therapy: For less severe tears, rest combined with targeted exercises helps healing.
  • Braces or Supports: To stabilize the knee during recovery.
  • Medications: Pain relievers and anti-inflammatories reduce discomfort and swelling.
  • Surgery: Often necessary for complete tears or highly active individuals to repair the ligament.

What to Expect During ACL Recovery

  • Rest: Time off from sports and activities to allow healing.
  • Physical Therapy: Exercises to restore strength, flexibility, and knee function.
  • Medications: As needed to manage pain.
  • Surgery Recovery: Following surgeon instructions and attending follow-ups for those who undergo surgery.

Can ACL Tears Be Prevented?

You can reduce your risk by:

  • Warming Up: Prepare your muscles before physical activity.
  • Strengthening Muscles: Strong leg muscles support and protect the knee.
  • Practicing Good Technique: Use proper methods when jumping, landing, or changing direction.
