cause of primary Osteoarthritis - unknown cause of secondary Osteoarthritis - trauma or infection, hemarthrosis, and osteonecrosis Osteoarthritis - disease that: -originates in the cartilage and affects underlying bone, soft tissue, and synovial fluid -slow progressive degeneration of joint structures -loss of mobility, chronic pain, deformity and loss of function Osteoarthritis can be known as either - OA or DJD Incidence of Osteoarthritis - -most common joint disease -before age 50, higher in men -65+ years: 60% men, 70% women -40 million in U.S. -adults over 30: 6% OA of the knee and 3% at the hip Structures involved in Osteoarthritis - -most common are the weight bearing joints- hip and knee -shoulder -lumbar -cervical spine -1st CMC -MTP joints Risk factors of Osteoarthritis - Growing evidence of systemic factors -genetics -nutrition and weight control -obesity -joint laxity -estrogen use -bone density -muscle weakness -serious injury and inherited predisposition= 50% of hands, hips and knees Men: occupational activities Women: post-menopausal Pathophysiology of Osteoarthritis -
~disorder of the whole synovial joint Stress causes thinning and a progressive loss of cartilage, inflammation develops, resulting in: -bony overgrowth at joint origin (spurs, osteophytes) -ligament laxity -progressive muscle weakness -Atrophy -Loss of function Signs and symptoms of osteoarthritis - -slow or sudden onset -tenderness on palpation and pain with activity -bony enlargement -limited joint ROM/stiffness -Crepitus (audible creaking of joints) -Inflammation -Joint effusion -typically starts on one side of the body and is an aching pain Heberden's nodes effect which joint because of malalignment and joint deformities with osteoarthritis?
