Guideline #:  CG-SURG-53 Publish Date:    12/27/2017
Status: Reviewed Last Review Date:    11/02/2017

Description

This document addresses elective total hip arthroplasty (THA) for hip damage severe enough to require replacement, when performed as an elective, non-emergent procedure and not as part of the care of a congenital, acute or traumatic event such as fracture (excluding fracture of implant and periprosthetic fracture). This procedure is also referred to as total hip replacement (THR) surgery, where the femoral head and acetabulum are replaced with a prosthesis that is anchored to the bone.

Note: Please see the following related documents for additional information:

Clinical Indications

Elective total hip arthroplasty is considered medically necessary when criteria are met for any of the following indications:

  1. Persistent, symptomatic degenerative joint disease (DJD), rheumatoid arthritis including juvenile rheumatoid arthritis/juvenile idiopathic arthritis (JRA/JIA) or hemophilic arthropathy as indicated by all of the following:
    1. Imaging evidence of significant joint destruction and cartilage loss (for example, hip joint destruction, severe narrowing, bone deformities); and
    2. Requires treatment as a result of disabling pain; and
    3. Individual has failed at least 3 months of non-surgical conservative therapy*; and
    4. Individual has limited hip function secondary to disease that interferes with ability to carry out age-appropriate activities of daily living (ADL); or

Discussion/General Information

In the standard total hip replacement operation, the femoral head and neck are removed, and the femoral canal (marrow space) is reamed-out. The damaged hip joint is replaced with an artificial prosthesis composed of two or three different components: 1) the head, (a metal ball, for example, stainless steel or cobalt chrome) that replaces the original femoral head, 2) the femoral component (a metal stem placed into the femur) and 3) the acetabular component (a plastic cup made of high-density polyethylene) that is implanted into the acetabulum. The stem may be secured using bone cement or press-fit for the bone to grow into it.

Hip replacement surgery is one of the most frequently performed inpatient procedures in the United States. According to the Centers for Disease Control and Prevention, nearly 332,000 THAs are performed annually in the United States (CDC, 2010). This number is expected to grow as the population ages. The vast majority of cases of THAs are due to degenerative joint disease, also known as osteoarthritis (OA). Approximately 14% of U.S. adults will be affected by OA during their lifetime. The rate of affected adults increases to 33.6% in those aged 65 years and older. However, OA does not always progress to the point where surgery is recommended; the need for elective THR surgery is limited to individuals who present with pain, impaired function interfering with ADLs, imaging evidence of significant joint destruction and cartilage loss, and failed conservative therapy. While OA progression cannot be reversed, conservative treatment can frequently slow or mitigate the progression of the disease. THA when done electively aims to re-establish functional joint movement and alleviate chronic joint pain associated with hip damage due to degenerative joint disease. Elective arthroplasty is used for reconstruction of a damaged hip joint resulting in refractory chronic joint pain or functional disability and to enhance quality of life. While hemophilia arthropathy is not a common condition, the hip joint can be affected by the disease. Bleeding into joints causes progressive damage to the articular cartilage leading to cartilage loss, pain and loss of function. These changes may ultimately lead to hip arthroplasty if conservative measures fail to alleviate symptoms.

The diagnosis of OA typically is made with the combination of clinical examination, laboratory testing and radiologic assessment, with x-ray images considered the gold standard in identifying OA and evaluating severity of disease. There several radiographic scoring systems which classify the extent of joint damage based upon pathophysiological joint signs visualized on radiographic images. Significant joint destruction can typically be visualized on radiological exams as subchondral cysts, subchondral sclerosis, osteophytes (bone spurs), joint narrowing, joint malalignment or subluxation, bone attrition or osteonecrosis.

Rheumatoid arthritis is a chronic inflammatory and progressive disease characterized by symmetrical joint involvement, which causes pain, swelling, stiffness, and loss of function in the joints. If left untreated, it may lead to joint destruction and progressive disability. Rheumatoid arthritis affects 2.1 million Americans usually striking people between the ages of 20 and 60, and people in their mid to late fifties are especially vulnerable. Rheumatoid arthritis is three times more common in women than in men. The traditional nonsurgical approach consists of non-steroidal anti-inflammatory drugs (NSAIDs) to reduce pain, swelling, and inflammation, plus a disease-modifying antirheumatic drug (DMARD) such as methotrexate to slow the course of the disease and prevent joint and cartilage destruction, physical therapy, or assistive devices. Total hip arthroplasty is considered for individuals who have exhausted other conservative treatment options. (AAOS, 2014)

Juvenile idiopathic arthritis (JIA), also known as juvenile rheumatoid arthritis (JRA), commonly occurs in children between ages 7 and 12 years old. JRA affects an estimated 300,000 children in the United States and approximately 1 in every 1,000 children develop some type of juvenile arthritis. In a study examining the arthroplasty rates between 1991 and 2005, Mertelsmann-Voss and associates (2014) noted that the rates of arthroplasty in the JIA population have significantly decreased. The authors suggest this decrease might be due to the effectiveness of DMARDs and biologic agents in preventing end-stage joint destruction if initiated early in the disease process. THA procedures in this population can be complex, structural abnormalities may exist, bone quality is frequently compromised, multiple joint involvement is common and due to the small size proportions, limiting implant options. This may contribute to poorer long term outcomes. THA provides an alternative for children with JRA who have failed medical treatment.

An elective THA may be considered as an option among other alternatives, weighing the potential risks and benefits prior to proceeding with total hip replacement. Complications associated with THA include deep venous thrombosis, pulmonary embolus, deep prosthetic infection, or periprosthetic fracture. Less than 1.0% of individuals undergoing THA die within the 30 day post-operative period. Approximately 10% of those who undergo THA will continue to experience residual pain for 6 or more months following surgery. A number of conservative interventions have been shown to be effective in controlling the symptoms of OA.

The OA Research Society International (OARSI) published recommendations in 2008 on the management of hip osteoarthritis recommending that orthopaedic surgical intervention proceed after more conservative treatment options were exhausted. Conservative treatments recommended include pharmacological interventions, such as capsaicin, paracetamol (acetaminophen), topical and oral non-selective non-steroidal anti-inflammatory drugs (NSAIDS), oral COX-2 inhibitors, and intra-articular glucocorticoids. OARSI recommended several core treatments appropriate for all individuals including but not limited to:

In 2012, the American College of Rheumatology (ACR) published updated recommendations for the use of nonpharmacologic and pharmacologic therapies in OA of the hip, including cardiovascular (land based or aquatic) and resistance exercise as well as weight loss in those who are overweight and the use of one of the following: oral or topical NSAIDS, Tramadol or intra-articular corticosteroid injections in those individuals who have failed full dose acetaminophen therapy.

Obesity is an independent risk factor for multiple diseases including joint deterioration (Perry, 2016). Within the overall population, the increase in the incidence of total joint arthroplasty parallels the rising rate of obesity. There is a general consensus that the risk of short term post-operative complications increases as weight increases, including wound infections, component malposition and in-hospital mortality (Perry, 2016). There does appear to be an increased revision rate for overweight or obese individuals five or more years following the initial surgery although this risk appears to be only moderately higher (Perry, 2016). Obese individuals have reported equivalent or superior clinical outcome satisfaction scores (Perry, 2016). There appears to be few options for those individuals with DJD who are overweight or obese. Smith and colleagues (2016) noted that those individuals with OA are at a greater risk of gaining weight due to reduced activity. While the authors of many of the studies recognized the increased complexity related to performing THAs on this population, the majority of studies recommended not withholding joint replacement surgery for overweight or obese individuals (Perry, 2016; Suleiman, 2012). The American Association of Hip and Knee Surgeons (2013) notes that TKA may be considered in obese individuals and states “expectations are for a steady, but slower improvement in the severe obese compared to non-obese patients post operatively”.

The World Federation of Hemophilia 2012 guidelines for the management of hemophilia recommend a similar treatment plan for those affected with chronic hemophilic arthropathy. Recommended conservative therapies include analgesics such as COX-2 inhibitors, physiotherapy to preserve strength and function, casting, bracing, orthotics, walking aids or home or activity modifications. If conservative treatment fails, joint replacement surgery might be needed for severe disease.
