Arthroplasty

The definition of arthroplasty is surgical joint replacement. During the procedure, your healthcare provider removes a damaged joint and replaces it with an artificial joint. The artificial joint (prosthesis) can be metal, ceramic or heavy-duty plastic. The new joint looks like the natural joint and moves in a similar way.

Most often, surgeons replace the hip joint, knee joint or shoulder joint. Providers call these procedures hip arthroplasty, total knee arthroplasty and shoulder arthroplasty. In the United States, surgeons perform about 500,000 hip replacements and more than 850,000 knee replacements every year.

Before arthroplasty, you may need several tests to evaluate your overall health such as blood work, an electrocardiogram and a chest X-ray. Depending on your health history, you may need to visit your primary care provider or another specialist for pre-operative evaluation. Some procedures require a CT scan or MRI for surgical planning.

A new joint usually lasts about 10 to 15 years. But everyone has different results after arthroplasty. Talk to your provider about what you can do to take care of your new joint. If your joint replacement wears out after 15 years, it may be possible to revise it with a new joint.

For the last 45 years,[when?] the most successful and common form of arthroplasty is the surgical replacement of arthritic or destructive or necrotic joint or joint surface with a prosthesis.[medical citation needed] For example, a hip joint that is affected by osteoarthritis may be replaced entirely (total hip arthroplasty) with a prosthetic hip. This would involve replacing both the acetabulum (hip socket) and the head and neck of the femur. The purpose of this procedure is to relieve pain, to restore range of motion and to improve walking ability, thus leading to the improvement of muscle strength.

He specializes in total joint arthroplasty of the hip and knee with numerous experiences. He is the Deputy Editor of Journal of Arthroplasty, Honorary Member of Hip Society and Founding Chairman of Arthroplasty Society in Asia (ASIA). Prof Wang is the president of Chinese Academy of Orthopedic Surgeons(CAOS) and the past President of Chinese Orthopedic Association(COA). Up to now, Prof Wang has published 137 peer-reviewed SCI papers, including 108 papers entitled by the first authors and corresponding authors.

Arthroplasty publishes original articles and reviews concerning joint replacement or the treatment of its complications, including clinical applications, surgical experience and prosthetic design. The journal will especially focus on the novel advances in the field of arthroplasty, including new technologies, biomaterials, prosthetic design etc.

But, the term "joint replacement" often scares people which is why many doctors use the term arthroplasty instead. Even so, joint replacement isn't as invasive as it sounds. Often, the surgeon just needs to remove a small part of your joint and replace it in a surgery known as partial joint replacement. But, this is only after they've tried various noninvasive methods first such as pain management and physical therapy.

These days, most arthroplasty surgeries are minimally invasive, which means the surgeon only has to make small incisions for removing and replacing damaged joint materials. Modern arthroplasty benefits are less damaging to tissue from surgery and quicker recovery times.

Shoulder arthroplasty is a very successful surgery for reducing pain and restoring mobility in people who have end-stage shoulder arthritis and sometimes following a serious shoulder fracture. Shoulder arthroplasty helps relieve pain and restore shoulder:

In knee arthroplasty, the surgeon removes portions of your bones that form your knee joint and replaces them with artificial implants. It's performed mainly for relieving stiffness and pain that osteoarthritis causes.

If you decide on knee arthroplasty, talk with the surgeon to see if you're an ideal candidate for minimally invasive surgery. This could involve less pain and a faster recovery than open surgery. If just one part of the joint of your knee is damaged, see if partial knee replacement may be an option for you. With this procedure, the surgeon will remove one side of your joint.

Hip arthroplasty is where the surgeon removes and replaces portions of your femur (thighbone) and pelvis that form your hip joint. They perform this procedure mainly for relieving hip stiffness and pain hip arthritis causes.

Individuals who have had arthroplasty can still go on to live active, functional lifestyles. One huge part of any rehabilitation program is exercise for restoring mobility, function, and strength to the impact joint and your surrounding muscles. Talk with your doctor about what a proper, post-operative rehabilitation plan might include.

Total knee arthroplasty (TKA) is one of the most successful and effective surgical options to reduce pain and restore function for patients with severe osteoarthritis. The purpose of this article was to review and summarize the recent literatures regarding patient satisfaction after TKA and to analyze the various factors associated with patient dissatisfaction after TKA. Patient satisfaction is one of the many patient-reported outcome measures (PROMs). Patient satisfaction can be evaluated from two categories, determinants of satisfaction and components of satisfaction. The former have been described as all of the patient-related factors including age, gender, personality, patient expectations, medical and psychiatric comorbidity, patient's diagnosis leading to TKA and severity of arthropathy. The latter are all of the processes and technical aspects of TKA, ranging from the anesthetic and surgical factors, type of implants and postoperative rehabilitations. The surgeon- and patient-reported outcomes have been shown to be disparate occasionally. Among various factors that contribute to patient satisfaction, some factors can be managed by the surgeon, which should be improved through continuous research. Furthermore, extensive discussion and explanation before surgery will reduce patient dissatisfaction after TKA.

The goal of the Arthroplasty Fellowship is to provide a comprehensive educational experience in total joint arthroplasty. Our faculty and the overall educational experience help the fellows refine their skills in the management of patients needing total joint replacements and revisions. The fellows develop their skills as educators, and they learn the basics of orthopaedic research.

Work alongside leading shoulder surgeons navigating the latest indications and strategies for total shoulder arthroplasty. From evaluation and planning through surgical application and post-operative management, advance your skills and discover technical pearls to optimize success.

These Guidelines for Medical Necessity Determination (Guidelines) identify the clinical information that MassHealth needs to determine medical necessity for knee arthroplasty. These Guidelines are based on generally accepted standards of practice, review of the medical literature, and federal and state policies and laws applicable to Medicaid programs.

Joint replacements involve removing a damaged joint and replacing it with prosthetic parts. You might have a total joint replacement, where a surgeon replaces the entire joint. A total joint replacement is also called a total joint arthroplasty. Or, you might have a partial joint replacement, where a surgeon removes and replaces only the damaged portion.

Originally this was called cement disease or aggressive granulomatosus.It is a histiocytic response that occurs as a result of macrophage reaction to any of the components, that are shed of the surface of the components of the arthroplasty.Nowadays it is mostly seen in non-cemented hips as a reaction to small polyethylene wear particles.Radiographically these aggressive granulomatous lesions present as focal radiolucencies around the prosthesis.The condition tends to occur between 1 and 5 years after surgery and is associated with smooth endosteal scalloping. The key feature is that it produces no secondary bone response.These characteristics help to distinguish small particle disease from infection, which often has more aggressive features, although the distinction is not always possible.Although particle disease is a result of polyethylene wear, you will not always see evident findings of polyethyleen wear in the acetabular cup,but whenever you see an eccentric position of the femoral head within the cup, look for focal lucencies.Large focal defects may be seen while the prosthesis is still stable.Particle Disease is relentlessly progressive with loosening, fracture and destruction of bone.Sometimes revision of a stable THA is needed because more bone loss would make revision surgery impossible.

Incidence post-operative: - cemented THA: 0.4% - press fit prosthesis: 2.5% - revision hip arthroplasty: 7.2% Usually it does not affect outcome, but may require cerclage cables. Sometimes a control perforation is placed by the surgeon during revision to aid in removal of the previously placed femoral component. Fractures during follow up are a result of loosening, particle disease, infection or severe cases of stress shielding.

Knee arthroplasty is a surgery to replace parts of the knee joint that have been damaged by arthritis or injury. This could involve resurfacing the joint, in which metal and plastic parts are used to replace the ends of the bones at the joint as well as the kneecap. Or it may be a total knee replacement, in which the entire joint is replaced with a prosthesis.

In hip arthroplasty, the surgeon removes damaged parts of the hip joint and replaces them with artificial parts. These may be made of metal, plastic, or ceramic. It may be needed when the hip is damaged from osteoarthritis, rheumatoid arthritis, or injury. 041b061a72
