A joint is where the ends of two or more bones meet. There are different types of joints within the body. For example, the knee is considered a “hinge” joint, because of its ability to bend and straighten like a hinged door. The hip and shoulder are “ball-and-socket” joints, in which the rounded end of one bone fits into a cup-shaped area of another bone.
When Is Total Joint Replacement Recommended?
Several conditions can cause joint pain and disability and lead patients to consider joint replacement surgery. In many cases, joint pain is caused by damage to the cartilage that lines the ends of the bones (articular cartilage)—either from arthritis, a fracture, or another condition.
If nonsurgical treatments like medications, physical therapy, and changes to your everyday activities do not relieve your pain and disability, your doctor may recommend total joint replacement.
Preparing for Surgery
In the weeks before your surgery, our surgical team will spend time preparing you for your upcoming procedure. For example, we will check your general health, and you may require several tests — such as blood tests and a cardiogram — to help plan your surgery.
There are also many things you can do to prepare. Talk to your doctor and ask questions. Prepare yourself physically by eating right and exercising. Take steps to manage your first weeks at home by arranging for help and obtaining assistive items, such as a shower bench, handrails, or a long-handled reacher. By planning ahead, you can help ensure a smooth surgery and speedy recovery.
Total joint replacement surgery takes a few hours. The procedure is performed in a hospital or outpatient surgery center.
During the surgery, the damaged cartilage and bone is removed from your joint and replaced with prosthetic components made of metal, plastic, or ceramic. The prosthesis mimics the shape and movement of a natural joint. For example, in an arthritic hip, the damaged ball (the upper end of the femur) is replaced with a metal ball attached to a metal stem that is fitted into the femur, and a plastic socket is implanted into the pelvis, replacing the damaged socket.
