Inflammatory Response in Robotic Total Knee Arthroplasty Versus Conventional Jig-Based and the Correlation with Early Functional Outcomes: Results of a Prospective Randomised Controlled Trial 

Description

In this video presentation, orthopedic trainee Andreas Fontalis from University College London discusses a randomized controlled trial (RCT) comparing robotic and jig-based conventional total knee arthroplasty (TKA). Fontalis highlights the high rates of patient dissatisfaction with TKA despite good clinical outcomes, indicating the necessity of preserving the periarticular soft tissue envelope to enhance rehabilitation results. The presentation dives into quantitative measures of surgical invasiveness, with inflammation markers serving as surrogates. Results show that robotic-assisted surgeries lead to reduced local and systemic inflammatory responses, indicated by significant decreases in IL-6 levels shortly post-operation. Fontalis clarifies the correlation of inflammation markers with early functional outcomes, particularly pain levels, demonstrating a moderate relationship with knee flexion and extension. He concludes that while the robotic approach minimizes inflammation, the study suggests further exploration into long-term outcomes to optimize surgical procedures for patient satisfaction.
