MCL Knee Pain

Knee injuries are common, and one of the most common types of knee injuries is an MCL (medial collateral ligament) injury. The MCL is a band of tissue on the inside of the knee that helps to keep it stable. When the MCL is injured, it can cause pain and instability in the knee.

In this article, we will discuss the causes, symptoms, treatments, and prevention of MCL knee pain.

What is MCL Knee Pain?

The MCL is a band of tissue that connects the thigh bone to the shin bone on the inside of the knee. It helps to stabilise the knee joint and prevent it from bending inward. MCL injuries occur when there is damage to this ligament, which can happen due to a direct blow to the outside of the knee or from twisting or bending the knee in the wrong direction.

Common Signs and Symptoms

The most common symptom of an MCL injury is pain on the inside of the knee. The pain may be mild or severe, and it may be worse when you put weight on the affected leg. Other symptoms may include swelling, stiffness, and tenderness along the inside of the knee. In more severe cases, you may feel a popping or tearing sensation at the time of injury.

How Can It Be Treated?

The treatment for MCL knee pain depends on the severity of the injury. Mild MCL injuries can often be treated with rest, ice, compression, and elevation (RICE) or follow the PEACE and LOVE protocol. You may also need to wear a brace or use crutches to keep weight off of the affected leg. Over-the-counter pain medications can help to relieve pain and inflammation.

For more severe MCL injuries, physiotherapy helps strengthen the muscles around the knee and improve range of motion. In some cases, surgery may be necessary to repair the damaged ligament.


MCL injuries can often be prevented by taking certain precautions, such as warming up properly before exercising, wearing protective gear (such as knee pads), and using proper technique when jumping or landing. Strengthening the muscles around the knee can also help to prevent MCL injuries.


MCL knee pain can be a frustrating and painful condition, but it is treatable with the right care. By taking the necessary precautions and seeking prompt medical attention, you can reduce your risk of MCL injuries and get back to your normal activities as soon as possible.
