About

Tom Jan Gieroba is a researcher whose work sits at the intersection of orthopedic biomechanics and surgical precision, with a particular focus on lower limb alignment. His primary research areas include the reliability of radiographic measurement techniques for knee alignment, the clinical implications of the arithmetic hip-knee angle (aHKA), and the optimization of preoperative planning for total knee arthroplasty (TKA). Gieroba’s major contribution lies in systematically evaluating the consistency and accuracy of aHKA measurements derived from long leg radiographs compared to computed tomography. His 2023 study, which has garnered 25 citations, demonstrated strong inter- and intra-observer reliability for the radiographic method, providing surgeons with a more accessible, lower-radiation tool for assessing coronal alignment—a critical factor in achieving personalized TKA outcomes. This work directly supports the shift toward kinematic and functional alignment strategies in knee replacement surgery. By validating a simpler measurement technique, Gieroba has helped bridge the gap between advanced imaging and routine clinical practice, empowering surgeons to make more informed decisions. His research is particularly valuable for orthopedic trainees and clinicians seeking evidence-based approaches to preoperative planning, underscoring his role in advancing the precision and reproducibility of knee alignment assessment.
