Osteoarthritis and Rheumatoid Arthritis and its Pathophysiology
Osteoarthritis (OA) is a noninflammatory, age-related disorder with a genetic factor associated with it and is best described as a wearing and tearing down of the articular cartilage in the synovial joint that commonly occurs in the knees, ankles, hips, hands, fingers, and wrist (Huether & McCance, 2017). In OA the articular cartilage is broken down due to thinning and the process of fibrillation which causes pain with weight bearing and use of the body part (Huether & McCance, 2017). As a result of the breakdown of the cartilage which leaves the subchondral bone vulnerable, the bone becomes sclerotic, develop cyst, and osteophytes that lead to erosion of the articular cartilage …show more content…

As an autoimmune disease, the synovial cells are affected and causes synovial membrane and joint damage because synovial fibroblast and the immune response initiates the release of cytokines, enzymes, prostaglandins that cause synovial tissue to thicken and loss of bone due to an abnormality in the immune response that causes a condition called synovitis (Huether & McCance, 2017). Because the signaling immune pathway is altered in the processes it causes additional inflammation, enzymes migration to the area, and ingrowth of blood vessels that allow more fibroblast to be able to travel to ligaments, tendon, other fibrous joint located throughout the body that contributes to its systemic effect (Huether & McCance, 2017). As a result of this process, inflammation spreads to surrounding ligaments, tendons, and affected joints and people experience joint pain, decrease mobility, and deformity (Huether & McCance, …show more content…

Osteoarthritis frequently affects the small finger joints and thumb, as well as the knees (Rheumatoid Arthritis.org, 2016). RA affects several joints in comparison to OA that affect one joint or area (Rheumatoid Arthritis.org, 2016). Osteoarthritis affects more people than rheumatoid arthritis. According to Rheumatoid Arthritis.org, (2016), 27 million people develop osteoarthritis and around 1.3 million people develop rheumatoid arthritis. Although OA is more prevalent in the population, females tend to be diagnosed are higher rates and experience the pain and stiffness alike (Rheumatoid Arthritis.org, 2016). RA appears in people between the age of thirty and sixty years of age. Osteoarthritis generally develops later in life. The signs and symptoms of RA are joint pain, stiffness, swelling joints, symmetrical symptoms, stiffness lasting greater than 30 minutes in the AM, fatigue, fever, and malaise (Rheumatoid Arthritis.org, 2016). In comparison, OA symptoms feature joint pain and stiffness which is unequally distributed and experienced in hands, fingers, knees, spine, and hips with stiffness in the AM lasting less than 30 minutes (Rheumatoid Arthritis.org, 2016). Another note is that with RA other diseases involving the lung, heart, musculoskeletal problems are common and continuous problems from the effects of inflammation (Huether & McCance,
