The other day, after a vicious jujitsu session at the gym, I noticed some pain coming from the side of the knee on the inner side of my leg. After some research, I found out that I had sustained a medial collateral ligament injury. Fortunately, my sprain appears only light, and I should be back at the gym in a short amount of time. Here’s a summary of what I learnt about MCL injuries…

What is a MCL injury?

A medial collateral ligament tear is a common type of knee injury, which often affects athletes, particularly those in contact sports. This type of injury is commonly referred to as a knee sprain. The MCL connects the thighbone to the shinbone along the inner side of the knee and provides stability to the joint.

As with other types of sprains, a MCL injury is the result of tearing or over stretching of the ligament. Typically, those receiving a MCL sprain will have incurred this injury through a sudden impact to the outer side of their knee. Such a force can push the knee laterally inwards, causing the MCL to stretch and eventually tear or become entirely detached from one of the bones it normally connects to.

Symptoms of a MCL Tear

Common symptoms of an MCL sprain is pain focused around the inside of the knee joint. Tenderness, swelling, redness, heat or bruising may also manifest as a result from this injury. In severe cases, the knee joint may feel completely unsupported when bearing weight. Such a sensation may be indicative of a complete detachment of this ligament to the bone.

How to treat a MCL sprain

Once a medial collateral ligament injury has been identified, it is important to immediately rest the affected knee joint. Further stress or movement can exasperate the injury causing additional damage to the ligament.

Applying ice to the inner side of the knee joint can minimize swelling, pain, and internal bleeding. It is recommended that ice is applied to the region for 20 minutes every two hours for the first 2 to 3 days. When ice is not available, any cold item that can be pressed upon the knee joint can be used. Even a wet towel is better than nothing.

Depending on the severity of the injury, rehabilitation or surgery may be needed in addition to resting the joint.  Always consult a physician, such as a qualified sport doctor, to ensure the best outcome for an injury involving the MCL. During recovery, mobility will often be affected, with some people needing crutches or a knee brace to assist their leg when walking.

Most MCL injuries can be healed overtime by properly resting the knee joint. To prevent future injuries to the knee, it is important to always warm up and stretch before performing physical exercise.
