Ajay Premkumar

About

Dr. Ajay Premkumar is a leading orthopedic surgeon and researcher whose work centers on the application of advanced technology in joint arthroplasty, with a specific focus on unicompartmental knee arthroplasty (UKA) and total hip arthroplasty (THA). His major contributions lie in critically evaluating and refining the use of robotic-assisted and computer-navigated systems to improve surgical precision and patient outcomes. In a landmark network meta-analysis (2021, 11 citations), Dr. Premkumar demonstrated that robotic-assisted UKA yields superior clinical and radiographic results compared to conventional and navigated techniques. He has also pioneered the concept of the "functional acetabular safe zone" in THA (2022, 6 citations), challenging traditional static targets by advocating for patient-specific, functional pelvic positioning to enhance implant stability. His work on the technically demanding lateral UKA (2023, 5 citations) and his analysis of national trends in technology-assisted navigation (2025) underscore his commitment to evidence-based adoption of surgical innovations. With a growing citation impact and a focus on practical, patient-centered solutions, Dr. Premkumar is shaping the future of precision joint replacement.
