Medical Overview

Understanding ACL injuries and their impact

What is an ACL Injury?

The anterior cruciate ligament (ACL) is one of the key ligaments that help stabilize your knee joint. The ACL connects your thighbone (femur) to your shinbone (tibia). It's most commonly torn during sports that involve sudden stops or changes in direction, jumping, and landing.

Common Causes

  • Sudden direction changes while running
  • Landing awkwardly from a jump
  • Stopping suddenly while running
  • Direct collision or tackle (football)
  • Pivoting with foot firmly planted

Symptoms

  • Loud "pop" sound at time of injury
  • Severe pain and inability to continue activity
  • Rapid swelling within hours
  • Loss of range of motion
  • Feeling of instability or "giving way"
