A joint forms 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 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 activity modifications do not relieve your pain and disability, your doctor may recommend total joint replacement.
Preparing for Surgery
In the weeks before your surgery, your surgical team and primary care doctor will spend time preparing you for your upcoming procedure. For example, your primary care doctor may check your general health, and your surgeon 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.
