6What is the role of joint replacement surgery?
Section snippets
The burden of disease
Changes in both population demographics and age-related quality of life expectations present the modern physician with a major challenge in managing degenerative conditions of the musculoskeletal system. In Western society, advances in treating the leading medical causes of mortality have progressively pushed average life-expectancy into the eight and ninth decades. Data from the United States of America indicate that those over age 65 comprise the fastest growing segment of the population.1
Effectiveness evaluation of joint replacement surgery
With the increasing cost of health care, there is a growing demand that the costs of treatment be justified by proven measurement of quality of life improvement. In determining the appropriate utilisation for joint replacement surgery, and thus defining its role in the treatment of degenerative disorders, effectiveness evaluation is critical. Regional variations in the frequency of joint replacement procedures and the lack of consensus regarding many aspects of related patient care, have
The growing importance of national joint replacement registers
Quality improvement in all aspects of the process of joint replacement surgery, from materials and component design, to surgical technique, to patient care, requires organised, longitudinal data collection as outlined above. In recent years, spurred by the pioneering efforts of Sweden and Norway, there has been a growing interest in the formation of national joint replacement registers that systematically follow all patients who undergo a specific replacement procedure.17., 18., 19. While the
Factors contributing to the evolution of joint replacement surgery
As has been substantiated in several national registers in recent years, the incidence of joint replacement procedures has increased at a faster rate than can be ascribed solely to the effects of population increase and population ageing.18., 19., 20., 21., 22. Projection data from the USA estimates that the number of total knee replacements in the female population will reach 274 000 procedures per year in 2030 versus roughly 155 000 per year today.1 The projections for total hip replacement
Effectiveness of joint replacement surgery
With this background of relevant issues, the following sections will discuss our current understanding of the effectiveness of joint replacement surgery in treating a variety of arthritic conditions.
Indications and contraindications
One way to tackle questions regarding the role of a treatment modality is to define conditions for which it should not be used in absolute and relative terms. The main absolute contraindication to any joint replacement surgery is active infection. This includes not only localised septic arthritis and osteomyelitis but also regional and systemic infection elsewhere in the body. Tooth abscesses, urinary tract infections and sinusitis, although remote from the affected joint, may haematogenously
Revision joint replacement
A detailed discussion of revision joint replacement is beyond the scope of this chapter but the following brief review highlights how the likelihood of revision surgery influences the primary process. While the quality and reliability of joint replacement surgery has advanced markedly over the past three decades, experience continues to demonstrate the finite lifespan of prosthetic components. Survivorship rates vary extensively depending on the factors mentioned above. It is impossible to
Summary
Joint replacement surgery represents one of the most significant advancements in the history of orthopaedic surgery and is widely accepted as an effective treatment for end-stage arthritis. The role of joint replacement surgery should be defined in terms of critical outcomes analysis. When the myriad of contributing factors is considered, it becomes apparent that the quantitative measurement of health-related quality of life improvement after joint replacement surgery cannot be divorced from

The potential application of a Cobalt Chrome Molybdenum femoral stem with functionally graded orthotropic structures manufactured using Laser Melting technologies
2013, Medical HypothesesCitation Excerpt :It has also been identified that future revision rates could continue to rise due to younger and more physically demanding individuals requiring joint arthroplasty. The prospects of revision surgery in this instance will have a significant effect on the longevity of orthopaedic implants [2]. Cementless fixation of the femoral stem by means of bone ingrowth has historically been used in younger and more active individuals who have undergone THA [3].

2011, Journal of Surgical ResearchCitation Excerpt :On one hand, it has become one of the most frequent causes of hospital admission for elective surgery, and its demand is projected to increase in the future: driven by the progressive shift towards an older population, characterized by a higher prevalence for arthritic disease [3]. On the other hand, in recent years, the mean age for primary intervention has shifted towards much younger ages [4]. Finally, implants tend to wear out with time and they need to be replaced through revision surgery.
The potential of stem cells in the treatment of knee cartilage defects
2010, KneeCitation Excerpt :Total knee replacement is a successful procedure for especially the less active older patient, although patients do not appear to return to normal function [11]. Despite improvements in biomaterials, implants and surgical techniques, the limited lifespan of prostheses make it less desirable for the younger and more active patients who put increased stresses and strains on their joint replacement [12]. For this group there is still a need to try and postpone or avoid the need for revision and re-revision surgery.

Typically performed on individuals between 65 and 80 years old joint replacement surgery is now being performed on individuals as young as 40 or as old as 90 (Parsons and Sonnabend, 2004). Individuals in their 40s and 50s have more rapid aseptic loosening from polyethylene wear.
