Audible snap in the knee

An audible snap can be from a tear or rupture of the anterior cruciate or posterior cruciate ligaments. Snapping of the knee can also be from a patellae dislocation or subluxation. 

Thickened area of the knee joint capsule (plica) can cause an audible snap as it is moved. A maligned patella can also produce an audible snap and is quite frequent in runners who run uphill. Other injuries that cause this symptom are listed below:
  • ACL Sprain

    ACL Sprain

    Anterior Cruciate Ligament injury or 'ACL injuries' are common in contact sports and especially those that are combined with sudden change of direction such as soccer or football. Often ACL tears do not occur in isolation and are in most cases are associated with damage to other structures within the knee such as the cartilage or the collateral ligaments.

  • Lateral Knee Ligament Sprain

    Lateral Knee Ligament Sprain

    A lateral ligament sprain is a knee ligament injury involving a tear to the ligament on the outside of the knee and is most likely following a direct blow to the inside of the knee.

  • Knee Sprain

    Knee Sprain

    A knee sprain is an injury or damage to any of the four ligaments which support the knee.

  • Acute Knee Injuries

    An acute knee injury usually occurs suddenly through either trauma or a twisting action. Pain in the knee can vary in severity from very mild to very severe and this depends on the injury mechanism (how the injury occurred) and the forces involved during the impact. It is strongly advised not to carry on playing if you have acute knee pain as this can easily progress to a chronic pain or to more complex knee injuries.
