2026 AAHKS Annual Meeting: Cement-in-Cement Re-Revision TKA: Durable Survivorship at Long-Term Follow-Up

92 patients undergoing cement-in-cement re-revision total knee arthroplasty (TKA) were retrospectively evaluated to determine the long-term effectiveness of retaining a well-fixed cement mantle during revision surgery. The primary outcomes of interest were cumulative incidences of aseptic re-revision, any re-revision, and reoperation. Secondary outcomes included Knee Society Scores (KSS), radiographic loosening, and factors associated with revision risk. Outcomes were assessed at 1, 5, and 10 years, with a mean follow-up of 7 years. Overall, the results revealed that cement-in-cement re-revision TKA demonstrated relatively low rates of aseptic re-revision, significant improvements in KSS, and minimal radiographic loosening. These findings suggested that cement-in-cement fixation may provide durable implant stability and improved clinical outcomes in appropriately selected patients undergoing complex revision TKA.
