Knee pain refers to pain that occurs in and around your knee joint. Knee pain can be caused by problems with the knee joint itself, or it can be caused by conditions affecting the soft tissues — ligaments, tendons or bursae — that surround the knee.
The severity of knee pain can vary widely. Some people may feel only a slight twinge, while others may experience debilitating knee pain that interferes with their day-to-day activities.
The knee is a complex joint that relies heavily on ligaments and muscles for stability. When pain is perceived as coming from the knee, all the anatomical components need to be examined, and in addition to the knee joint, the low back, pelvis, hip, ankle and foot need to be examined due to the direct influence they have on the knee, and vice versa.
