Hannes Vermue

About

Hannes Vermue is a leading researcher in orthopaedic surgery, with a primary focus on the clinical and economic evaluation of robotic-assisted total knee arthroplasty (TKA). His work critically examines how robotic systems impact surgical precision, patient outcomes, and healthcare costs. Vermue’s major contributions include demonstrating that while robot-assisted TKA has a learning curve for surgical time, it does not compromise component alignment or gap balancing—a finding from his highly cited 2020 study (123 citations). He has also advanced the field by systematically reviewing the evidence for various robotic systems (63 citations) and by using Markov decision analysis to assess cost-effectiveness (47 citations), providing crucial data for hospital adoption decisions. Beyond technical outcomes, Vermue has explored patient-specific alignment and standardized laxity testing, with a recent randomized controlled trial (2025) showing no clinically important improvements from intraoperative robotic laxity assessment at two years. His work challenges assumptions and guides evidence-based integration of robotics into the operating theatre, making him a key voice in the evolution of modern knee arthroplasty.
