Abstract

Although revision total knee arthroplasty (TKA) procedures are successful in relieving pain and restoring function in failed knees, long-term results are inferior to primary procedures. Mobile bearing (MB) revision knees can potentially improve functional performance. Clinical results of 44 MB rotating platform (RP) revision TKAs demonstrated mean knee injury and osteoarthritis outcome score (KOOS) activity of daily living score of 77 2 years postoperatively. Clinical results were put into context through wear testing which demonstrated improved wear performance compared with fixed bearing (FB) revision knees. The RP construct is a good choice for revision TKA because it permits the surgeon to align the tray for fixation, not compromise rotation of the tibial insert, and reduce transmission of shear stresses to the bone, cement and implant interface, which is a known cause of failure.
