Study Seeks the Ideal Technique and Construct for Aseptic Revision TKA
A study assessing re-revision total knee arthroplasty (TKA) based on the components revised, the implant choice, and the construct fixation received the 2025 AAHKS Surgical Techniques and Technologies Award at the recent annual meeting of the American Association of Hip and Knee Surgeons.
The study from Australia used national registry data to retrospectively review outcomes among more than 21,000 patients who had undergone an aseptic revision TKA between September 1999 and December 2023. The researchers recorded the revision TKA construct used (stems and/or cones/sleeves) and the components exchanged (femur, tibia, and/or liners).
The primary outcomes were:
- All-cause re-revision
- Re-revision for loose components
The results showed that higher all-cause re-revision and component loosening occurred among patients who had a TKA revision:
- With a tibial stem only; no sleeves/cones
- Without the use of stems or sleeve/cones
- With partial revision of the tibia or femur
The researchers concluded that in aseptic revision TKA, exchange of both femoral and tibial components with stems and cones/sleeves in the revision construct has the lowest re-revision and component loosening rates.
