[2015] Kristine Bartlett: Orthopedics

Types of Arthritis that May Lead to Knee ReplacementOsteoarthritis occurs when cartilage on the gliding surface of the knee begins wearing away, causing pain and stiffness. When the cartilage wears away completely, the bones rub directly against each other causing decreased mobility and chronic pain. Osteoarthritis is most common in people 50 and older, but is also prevalent in those with a family history of arthritis or those with lifestyles that stress the joints, such as athletes and laborers.Rheumatoid arthritis is actually an autoimmune disease in which the body’s immune system begins to attack the synovial membrane causing it to become inflamed and overproduce synovial fluid (the fluid that lubricates your joints). More importantly, the process also causes damage and wear to the articular cartilage.Traumatic arthritis results from a serious knee injury, such as a fracture, ligament damage or meniscus tear. The impact of the accident also causes mini trauma to the articular cartilage which over time, develops into osteoarthritis, causing knee pain and stiffness.
