Joint replacement can help relieve pain and enable you to live a fuller, more active life. If you and your orthopaedic surgeon have decided that you are a good candidate for joint replacement, you are in good company: In 2016, almost 1.25 million hip and knee replacement surgeries were performed in the United States, making it one of the most common orthopaedic procedures performed today.

Arthroplasty means the surgical repair of a joint. Orthopaedic surgeons performing an arthroplasty use metal and/or plastic parts to reconstruct degenerative, damaged, or arthritic joint surfaces in patients with severe arthritis who have failed nonsurgical treatment and have disabling function, limitation of activities of daily living, and severe pain.

You may know someone who had hip or knee replacement surgery and went home the same day. In the past, hip and knee replacement surgery required a hospital stay lasting several nights. With advances in procedural techniques, anesthesia medications, pain management and rehabilitation, some people can now have a joint replacement surgery without spending a night in the hospital.

Osteoarthritis (OA) is a common disorder caused by a loss of cartilage that affects the joints.

If you need total knee or total hip replacement surgery—and your weight is significantly higher than it should be—your doctor may advise you to lose weight before your procedure. Even though you may feel fit and healthy at your current weight, studies show that a patient with a BMI greater than 40 is more likely to experience serious complications both during and after surgery than a patient of normal weight. Your doctor wants you to be aware of these risks so that you can take steps to minimize them before your procedure.

Total knee replacement (also called knee arthroplasty) is a common orthopaedic procedure that is used to replace the damaged or worn surfaces of the knee. Replacing these surfaces with an implant or "prosthesis" will relieve pain and increase mobility, allowing you to return to your normal, everyday activities.

Total hip replacement (also known as hip arthroplasty) is a common orthopaedic procedure and, as the population ages, it is expected to become even more common. Replacing the hip joint with an implant or "prosthesis" relieves pain and improves mobility so that you are able to resume your normal, everyday activities.

During knee replacement surgery, an orthopaedic surgeon will resurface your damaged knee with artificial components, called implants.

Knee and hip replacements are two of the most commonly performed elective operations. For the majority of patients, joint replacement surgery relieves pain and helps them to live fuller, more active lives.

Hip and knee surgeons are not surprised when they find that someone who comes into the office for a problem had a hip or knee replacement done many years prior without any further follow up. Many people are unaware that they should follow up with their surgeon as part of the long-term care for joint replacements. Despite most hip and knee replacements now lasting for 15-20 years, it is important to follow up and not take your new joint for granted.
