A Randomized Controlled Trial of Gap Balancing and Measured Resection Techniques for Bi-Cruciate Stabilized Total Knee Arthroplasty

Description

In this presentation, Jordan Broberg discusses a randomized controlled trial comparing gap balancing and measured resection techniques in bi-cruciate stabilized total knee arthroplasty (TKA). He begins by introducing the concept of bi-cruciate stabilization and referencing the JOURNEY TKA device by Smith & Nephew, which previously faced issues with high revision rates but has shown improved survivorship in its new iteration, the JOURNEY II. Broberg outlines the study's objectives, focusing on the differences in surgical techniques and evaluating implant migration, joint kinematics, and patient functional performance using various measurement tools, including radiostereometric analysis and the timed-up-and-go test. He highlights findings related to early tibial migration and indicates that both surgical approaches result in similar implant kinematics and patient outcomes, suggesting that either technique can effectively support the use of the bi-cruciate stabilized implant for TKA. The presentation concludes with a thank you to those involved in the study and mentions funding sources.
