A torn ACL (anterior cruciate ligament) injury is a common and often debilitating condition affecting the knee. The ACL is a vital ligament that connects the thigh bone (femur) to the shinbone (tibia), playing a crucial role in stabilizing the knee joint during movements like running, jumping, and changing direction.
This type of injury typically occurs when the ACL is subjected to excessive force or stress, leading to partial or complete tearing. Sports activities such as football, basketball, soccer, and skiing, which involve sudden stops, pivoting, or direct impact to the knee, are frequent causes of ACL tears. Additionally, non-contact injuries can occur during activities like jumping and direct hits to the knee.
Symptoms of a torn ACL can vary but commonly include:
Audible or Sensory Pop: Many individuals report hearing or feeling a popping sensation at the time of injury.
Pain: ACL tears often cause immediate and intense pain in the knee, making weight-bearing difficult.
Swelling: Rapid swelling within hours of the injury is typical, indicating inflammation and possible joint damage.
Instability: The knee may feel unstable or give way during activities, impacting mobility and confidence in movement.
If you suspect a torn ACL, seeking immediate medical evaluation is crucial.
