Bruising on the knee

Bruising on the knee occurs when bleeding from within the knee joint works its way to the surface. This is usually due to an anterior cruciate (ACL) tear or rupture. It may track down the leg due to the effects of gravity over time.

 

 

Bruising can also occur due to medial collateral (MCL) and lateral collateral (LCL) tears. Quadricep (thigh) muscle contusions can also create bruising on the knee from a direct impact or trauma. Injuries 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.

  • Knee Contusion

    Knee Contusion

    A knee contusion or bruised knee occurs due to an impact on the knee. This can be due to a fall directly onto the knee or something hitting the knee, such as a ball or club. Contusion is the medical term for a bruise. Treatment depends on how bad the injury is.

  • Knee Sprain

    Knee Sprain

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

  • Acute Patella Injury

    Acute Patella Injury

    An acute patella injury is an injury to the kneecap or patella from a direct blow or fall onto the knee. A fracture of the patella is also possible.

  • Unhappy Triad of the Knee

    Unhappy Triad

    The unhappy triad is a severe injury which involves damage to three of the four major ligaments in 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.
