Insights

Revision surgery for infected hip arthroplasty has a higher persistent infection rate than aseptic loosening. The risk of reinfection after successful revision continues for many years.

Area of Science:

  • Orthopedic Surgery
  • Infectious Disease

Background:

  • Infected arthroplasty poses significant challenges in revision surgery.
  • Understanding long-term infection persistence is crucial for patient outcomes.

Purpose of the Study:

  • To evaluate the long-term infection persistence after revision surgery for infected hip arthroplasty.
  • To compare infection rates with revision for aseptic loosening.

Main Methods:

  • Retrospective review of 98 hips (96 patients) undergoing revision for infected arthroplasty.
  • Analysis of persistent infection and late reinfection rates.
  • Follow-up of 70 hips with initially successful revision for a mean of 5.9 years.

Main Results:

  • Infection persisted in 28 out of 98 hips.
  • In 70 hips with initially successful revision, 10% developed infection after 3 years and 26% after 10 years.
  • The infection rate after revision for septic arthroplasty is higher than for aseptic loosening.

Conclusions:

  • Revision surgery for infected arthroplasty has a higher risk of persistent infection.
  • The risk of developing late infection after initially successful revision continues for many years.
  • Long-term surveillance is essential for patients undergoing revision for infected arthroplasty.
