Pain on the outer (or lateral) part of the knee can be caused by an injury. It may also be the result of inflammation in a band of tough fibrous tissue that runs down the outside of the thigh, and attaches to the front of the tibia (shin bone). Pain in this area may also be caused by arthritis.

What is the outside of your knee called?
The outside half (farthest away from the other knee) is called the lateral tibial plateau, and the inside half (closest to the other knee) is called the medial tibial plateau. The patella glides through a special groove formed by the two femoral condyles called the patellofemoral groove.
Can you tear all the ligaments in your knee?
