About

A. Lahmer is a pioneering researcher in orthopaedic biomechanics, with a focused expertise in computer-assisted and robotically-assisted joint replacement surgery. His major contributions lie in experimentally validating the precision and stability of robotic bone preparation for total hip and knee arthroplasty. In his most-cited work (27 citations), Lahmer conducted a seminal experimental study comparing robotically-milled bone cavities (using Robodoc and CASPAR systems) against traditional hand-broaching, demonstrating the superior primary rotational stability of cementless stems. This foundational research directly addressed the critical challenge of implant micromotion and long-term fixation. He further advanced the field by developing a dedicated planning system for computer-assisted total knee replacement (11 citations), aiming to improve the accuracy of bone resections and prosthetic alignment. Lahmer’s work is notable for its rigorous experimental design, using synthetic femora and custom measurement apparatus to provide objective, reproducible data. His comparative studies have helped establish the clinical importance of robotic preparation in achieving optimal implant stability, influencing the adoption of surgical robotics in orthopaedics.
