About

Dr. Raj Karia is a leading figure in orthopaedic biomechanics, with a primary focus on the kinematics of knee arthroplasty. His research centers on understanding how different surgical techniques—particularly robotic-assisted versus conventional methods—affect joint motion and patient outcomes. In his highly cited 2013 study, "Comparison of Robot Surgery Modular and Total Knee Arthroplasty Kinematics," Dr. Karia pioneered a detailed analysis of knee specimens using a custom crouching machine to track femoral condyle movement from 0 to 120 degrees of flexion. This work, which has garnered 13 citations, provided foundational insights into the anterior-posterior positioning of the lateral and medial condyles relative to the tibia, offering critical data for improving implant design and surgical precision. Dr. Karia’s contributions are instrumental in advancing robotic surgery for knee replacements, directly impacting how surgeons optimize modular and total arthroplasty to restore natural knee function. His meticulous approach to measuring joint kinematics continues to influence both clinical practice and biomechanical research, making his work essential reading for students and researchers in orthopaedic engineering.
