Stop Using Tourniquets for TKA Cementation: Here's a Better Way

Exploring the radiographic data across 7 zones to understand how CO2 gas clears cancellous bone better than saline alone.

Although cemented total knee arthroplasty (TKA) is a widely successful procedure to treat many forms of arthritis, aseptic loosening remains one of the primary causes for early and late revisions. Studies and the 2017 national registries report that up to 28.7% of all revisions are due to aseptic loosening.

An evaluation of TKA failures estimated that 40% of early revisions could be avoided, in part, with optimal cement fixation. Increasing the amount of cement in the tibial and femoral bone (cement penetration) has been shown to provide a stronger bone-cement interface, which leads to increased stability and long-term survivorship of the implants.
