Common Knee Disorders
Traumatic injury to the knee
Rheumatoid (inflammatory) arthritis
The knee is a major weight-bearing joint that is held together by muscles, ligaments, and other important soft tissue. Cartilage is the material inside the joint that provides shock absorption to the knee during weight-bearing activities such as walking or stair climbing.

Bones, ligaments, cartilage, and tendons all work together to build a healthy knee.
