Septic complications are on the rise and aseptic loosening has decreased in total joint arthroplasty: an updated complication based analysis using worldwide arthroplasty registers.

Abstract in brief

• Septic complications, such as infections, are becoming the main reasons for revision surgeries in total knee replacements (TKA) and are also increasingly significant in total hip replacements (THA), signaling a shift from previous leading causes like aseptic loosening.
• Aseptic loosening, which was once the most common cause for both THA and TKA revisions, has decreased in relative risk over the past decade, though it remains a primary reason for reoperation.
• The study, based on data from national joint registries across seven countries, highlights changing trends in revision causes, with infections now playing a larger role compared to earlier years.
