Outside Knee Pain (Lateral)
Lateral knee pain occurs on the outside of the knee and 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.
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.
A 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 a traumatic injury as well as degenerating over time.
The peroneal nerve is a branch of the sciatic nerve which runs down the outside of the lower leg, serving the peroneal muscles which help pull the foot upwards and inwards. Symptoms include numbness & tingling in the lower leg and are often caused by a blow to the outside of the knee.
Dislocation of the proximal tibiofibular joint occurs most commonly when the athlete sustains an impact or falls with their knee in a fully bent position. It is an injury to the joint at the top of the shin where the two shin bones meet at the knee.
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. The treatment of this knee injury depends on the underlying cause of the condition.
