Arthritis is a multifactor process in which we often see the articular cartilage as the center of pathology. However, other influences such as the synovium, supportive soft tissues (ligaments, muscles, tendons and capsules), anatomic position or alignment, and the subchondral bone and marrow play important roles in disease progression. The fundamental goal of the treatment of lower extremity joints is to stave off arthritis and preserve motion.
