The role of isolated polyethylene exchange in total knee arthroplasty

[摘要] Total knee arthroplasty (TKA) is a very successful operation that can deliver great patient satisfaction1,2 with good implant survivorship.3 Notwithstanding this, the number of revision TKAs is on the rise for a myriad of reasons, including surgical technique and patient selection.4 Midflexion instability owing to excessive joint line alterations, as well as poor patient selection for unicompartmental arthroplasty causing early failure, have contributed to a rise in the incidence of revision TKA. In the current literature, the most common reasons for revision TKA are aseptic loosening, usually as a result of wear, and infection.2,5-8 These, together with instability and stiffness, account for 80% to 90% of all revisions.
