Does Neutral Mechanical Alignment Improve the Durability of Revision Total Knee Arthroplasty?

 

Dallas, November 3, 2018 — “While neutral mechanical alignment remains a useful goal in revision total knee arthroplasty, factors other than static coronal alignment may be as important in determining durability,” a study presented at the 2018 Annual Meeting of the American Association of Hip and Knee Surgeons concluded.

Author, Matthew P. Abdel, MD, and co-authors, Nicolas Reina, MD, PhD, Christopher G. Salib, MD, Robert T. Trousdale, MD, Daniel J. Berry, MD and Mark W. Pagnano, MD, hypothesized that a neutral alignment achieved in revision total knee arthroplasty procedures would result in better long-term implant durability and positive functional outcomes for patients. They compared aseptic loosening, re-revisions and Knee Society Scores in neutrally-aligned and outlier revision total knee arthroplasty groups.

In studying the 981 knee revisions in 846 patients in a large cohort between 2004 and 2014, they “could not demonstrate a difference in functional outcomes or 10-year implant survivorship” in those knees in the neutrally aligned group and those in the outlier groups.
