Knee pain is the most common musculoskeletal complaint that brings people to their doctor. With today's increasingly active society, the number of knee problems is increasing. Knee pain has a wide variety of specific causes and treatments.
The knee joint's main function is to bend, straighten, and bear the weight of the body, along with the ankles and hips. The knee, more than just a simple hinged joint, however, also twists and rotates. In order to perform all of these actions and to support the entire body while doing so, the knee relies on a number of structures including bones, ligaments, tendons, and cartilage.
