Outside knee pain

Pain on the outside of the knee or lateral pain can be from the lateral collateral ligament (LCL). Side of knee pain can also indicate an issue with the head of fibula this could be from direct trauma causing a fracture or from the peroneal nerve. Side knee pain can indicate an issue with the iliotibial band (ITB) where friction and tightness can occur.

Pain on outside of knee can also be from a contusion tracking down from the quadriceps higher up. Outside of knee pain can also be caused due to a large effusion or swelling from the knee joint injury. Injuries are listed below:
  • Lateral Knee Ligament Sprain

    Lateral Knee Ligament Sprain

    A lateral ligament sprain is a knee injury involving a tear to the ligament on the outside of the knee. It is most likely occurs following a direct blow to the inside of the knee which causes overstretching of the knee. Here we explain the treatment, rehabilitation and exercises as well as strapping and taping to return you back to full fitness.

  • Iliotibial Band Syndrome

    Iliotibial Band Syndrome

    Iliotibial band syndrome is a common cause of pain on the outside of the knee caused by friction as the tendon rubs over the bone. It usually comes on gradually over time getting progressively worse until eventually running must stop. Typically the athlete will rest for a period of time until symptoms go only for them to return so far into a run when training resumes.

  • Lateral Meniscus Tear

    Lateral Meniscus Tear

    Lateral meniscus tear is an injury to the semi circular cartilage on the outside of the knee joint. Symptoms include tenderness and pain around the outside surface of the knee. Each knee joint has two crescent shaped cartilage menisci which cushion and support the knee. They can be injured by twisting or traumatic injury as well as degenerating over time.

  • Knee Synovitis

    Knee Synovitis

    Knee synovitis occurs when the synovial membrane which lines and lubricates the knee joint, becomes inflamed. Swelling or stiffness in the knee joint may develop following another injury or from arthritis or gout.

  • Knee Sprain

    Knee Sprain

    A knee sprain is a tear to any of the four ligaments which support the knee and can include lateral ligament sprains on the inside or outside of the knee, or tears to the cruciate ligaments deeper inside the knee joint. Often knee sprains are complicated involving injury to more than one ligament as well as other structures in the joint.

  • Posterolateral Corner Injury

    Posterolateral Corner Injury

    Posterolateral corner injuries cause pain at the back and outside of the knee. They are not particularly common injuries, although around half of cases occur due to sporting injuries, with road traffic accidents being another common cause.

  • 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.

  • Outside Knee Pain (Lateral)

    Lateral knee pain is that which occurs on the outside of the knee has come on gradually as opposed to an acute knee joint or ligament injury. If you are not sure what is causing your pain then why not check out our symptom checker? The most common causes of pain on the outside of the knee are Iliotibial band friction syndrome and Lateral cartilage injuries. Here we explain the most widely seen causes, less common causes of lateral knee pain as well as important injuries that should not be missed.
