Total Hip Replacement
If your hip has been damaged by arthritis, a fracture, or other conditions, common activities such as walking or getting in and out of a chair may be painful and difficult. Your hip may be stiff, and it may be hard to put on your shoes and socks.
Common Causes of Hip Pain: Osteoarthritis.Rheumatoid arthritis.Post-traumatic arthritis, Avascular necrosis. Childhood hip disease.
In a total hip replacement (also called total hip arthroplasty), the damaged bone and cartilage is removed and replaced with prosthetic components.
Recovery: The success of your surgery will depend in large measure on how well you follow your orthopaedic surgeon's instructions regarding home care during the first few weeks after surgery.
