Aging and Arthroplasty The effect of aging on joints varies considerably from person to person. By age 80, almost everyone develops some type of degeneration in the knees, elbows, hips, and shoulders. – Osteoarthritis is at least partially age-related. – Aging results in thinning of the articular cartilage and decreased production of synovial fluid in joints. – Ligaments shorten and lose elasticity.
Joint arthroplasty is the surgical implantation of an artificial joint. The most commonly replaced are the hips, knees, and shoulders. – Partial hip replacements involve only the femur, while total hip replacements involve both the acetabulum and head of the femur. Aging and Arthroplasty
Potential complications of arthroplasty include infection, blood clotsand nerve injury.
