Lateral knee pain may occur due to various conditions.
Anterior Cruciate Ligament Injury
This type of knee injury tears or overstretches a ligament that causes pain on outside of knee radiating down leg. You may experience a complete or partial tear.

Iliotibial Band Syndrome
When a band of connective tissue rubs on the outside of your knee, it will lead to iliotibial band syndrome development.
The lateral knee has a thick band of fibrous tissue known as the iliotibial band, and they usually run from your hip to below your knee on the outer side of the leg.
You will notice an increased soreness and inflammation from your thigh bone to your knee if there is a continuous and vigorous bending and straightening of the leg.

Lateral Cartilage Meniscal Injury
Meniscal injury is highly associated with meniscal cartilages damage inside your knee. The meniscal cartilages are essential as shock absorbers and can easily tear when you twist your knee while the foot is on the ground.
Sportspeople have a high chance of experiencing this type of injury due to the constant change of direction in most sports- such as soccer and basketball.
Besides, people who perform manual or construction labor can experience this kind of pain. Additionally, old age contributes to meniscus injury because of wear and tear.
Lateral Collateral Ligament Injury
A ligament is thick fibrous tissue that joins two bones together. And the collateral ligament runs down on the outer side of the knee.
Blows inside your knees lead to collateral ligament injury. The impact stretches from the lateral side (outside) of your knee and damages the ligament.
