How to recognize pain on the outside of the knee and what you can do
Pain on the outside of the knee is common, especially in people who run, cycle, or often move on uneven terrain. It is often due to an overload or injury of the structures on the outside of the knee. This could be runner's knee, an injury to the outer meniscus, or in some cases, an injury to the lateral collateral ligament. Regardless of the cause, the right measures can help you reduce pain and return to activity faster.
Possible symptoms
The pain is often experienced as a sharp or burning sensation on the outside of the knee during exertion. It can develop gradually during longer activities or appear suddenly with a specific movement. In some cases, swelling or stiffness also occurs, making it difficult to fully bend and straighten the knee. With runner's knee, the pain often disappears with rest but quickly returns when activity is resumed.
- Sharp or dull pain during exertion, especially during or after running
- Tenderness localized to the outer side of the knee joint
- Swelling or a feeling of warmth over the area
- Pain that subsides with rest but returns with movement – especially when running, cycling, or climbing stairs
Common causes of pain on the outside of the knee
One of the most common causes is runner's knee, where the tight iliotibial band rubs against the outside of the femur, causing irritation. It is common among runners and cyclists but can also affect people who train a lot on hills or uneven terrain. The pain can also be caused by an outer meniscus injury that occurs with twists or rapid sideways movements. In rarer cases, it may be an injury to the lateral collateral ligament, usually after a strong lateral load. In older people, lateral osteoarthritis, where the cartilage on the outside wears down, can cause long-term pain and stiffness.
The difference between outer and inner knee pain
Pain on the outside is most often linked to runner's knee, outer meniscus injury, or lateral collateral ligament injury, while pain on the inside is often due to inner meniscus injury, MCL injury, or strain from overpronation. By distinguishing between these, you can choose the right treatment and aids.
When you should seek medical care
Many complaints resolve with self-care, but there are times when you should seek a professional assessment. If you experience severe pain that does not improve in a few weeks, if the knee is unstable, or if you suspect a ligament or meniscus injury, it is wise to contact medical care. For long-term stiffness and pain, an investigation for osteoarthritis may be needed.
What you can do yourself
For acute problems, it is good to reduce the activity that triggers the pain. Rest does not mean total stillness – walking, light cycling, and non-weight-bearing exercises for the outside of the knee can be beneficial. Stretching the hip and thigh muscles can relieve runner's knee, while strength training for the hips and core helps stabilize the knee joint. A knee brace that offloads the outside of the knee can provide support and reduce pain during activity.
Exercises that can relieve pain on the outside of the knee at home
Start with simple movements and gradually increase as the pain subsides.
A good exercise is to stand on one leg and slowly bend the knee a few centimeters, hold your balance for ten seconds, and switch legs. You can also lie on your side and lift the upper leg straight up and down at a calm pace to strengthen the outside of the hip. A third exercise is to stand with your feet wide apart and slowly shift your weight from side to side, which loosens and strengthens both legs.
Preventive advice
To avoid recurring problems, it's good to vary your training and avoid sudden increases in intensity. Strength training for the hips, core, and thighs gives the knee better stability during lateral loads. The right shoes for your foot type and terrain adapted to your activity also reduce the risk of recurrence.
Our products that can help you
We offer knee braces that provide support for runner's knee and lateral loading, as well as elastic bandages that provide compression and relief. For extra stability during lateral movements, you can choose models with reinforced side stays. Find the support that suits your needs and return to a more active everyday life.
Do knee braces help with pain on the outside of the knee?
Yes, a knee brace can relieve pressure on the outside of the knee and provide support during activity. It is particularly useful for runner's knee or after minor ligament injuries.
What is the most common cause of pain on the outside of the knee?
The most common cause is runner's knee, also known as iliotibial band syndrome, where a tendon band rubs against the outside of the knee during exertion.
Can pain on the outside of the knee go away on its own?
Yes, many complaints are relieved with rest, adapted exercise, and stretching. The recovery time can vary from a few weeks to several months depending on the cause.
How do I know if I have runner's knee?
With runner's knee, the pain is usually felt during activity, especially when running or cycling, and it disappears with rest. It can return quickly when you start to exert yourself again.
Can an outer meniscus injury cause the same symptoms as runner's knee?
Yes, both can cause pain on the outside of the knee, but a meniscus injury often causes locking, swelling, and sometimes instability in the knee joint.
What exercises are good for pain on the outside of the knee?
Strength exercises for the hips and thighs, such as side leg lifts and single-leg squats, can provide stability. Stretching the hip and iliotibial band can reduce tension.
How can I prevent pain on the outside of the knee?
By gradually increasing training volume, using the right shoes, training hip and core strength, and avoiding repetitive movements, you reduce the risk.
When should I seek medical care for pain on the outside of the knee?
If the pain is severe, does not improve after a few weeks, or if the knee feels unstable, you should contact medical care for an assessment.
