Trends in types of revision for prosthetic joint infection and risk of a second revision from 1995 to 2022: A descriptive cohort study from the Danish Hip Arthroplasty Registry.

This protocol outlines a register-based cohort study utilizing Danish Hip Arthroplasty Register data from 1995 to 2022. Focusing on adult patients undergoing primary total hip arthroplasty (THA), the study categorizes revisions, particularly periprosthetic joint infections (PJI), into Debridement, antibiotics, and implant retention (DAIR), one-stage, and two-stage approaches. Annual revision numbers and the risk of a second revision after each primary type will be analyzed. The studys strengths lie in its comprehensive examination of various PJI revision methods and an extended recording period, leveraging the DHRs high completeness rates. While acknowledging potential uncertainties, the study offers valuable insights into THA revision trends, aiding in clinical practice optimization and improving patient outcomes.
