Revision Burden: Projections in the United States and Worldwide
摘要
The revision burden of total hip arthroplasty is defined as the proportion of revision surgeries relative to the total number of arthroplasties performed. As indications for primary THA (pTHA) expand, alongside aging populations and increased life expectancies, there is an anticipated exponential rise in pTHA procedures both in the United States and globally. While the rate of revision THA (rTHA) is also expected to increase, it is projected to do so at a slower pace compared to pTHA, resulting in a decreased revision burden. Nevertheless, this decrease should not overshadow the significant challenges posed by rTHA in the future. Revision THA is a complex and resource-intensive procedure, often associated with higher risks, more frequent complications, increased costs, and less favorable outcomes compared to pTHA. Traditional causes for revision surgeries, such as aseptic loosening and instability, are increasingly being replaced by periprosthetic joint infection (PJI). Advanced surgical techniques, cutting-edge technology in surgical training, improved implant materials, and enhanced diagnostic tools may prove crucial in managing and potentially reducing the incidence of rTHA.
