[Why are we revising our primary knee arthroplasties? An evaluation of the causes for revision of primary knee arthroplasties over a five-year period (2018-2022)].

knee arthroplasty revision surgery in our environment is determined by different patterns depending on the chronology. Joint stability is the main determinant of revision in the first two years, while aseptic loosening seems to predominate in the long term, with infection in the background. Revision of primary knee arthroplasty remains to be a surgical challenge, as 11.8% of patients required an additional revision surgery, especially in younger patients.
