Vinaya Rajahraman

About

Vinaya Rajahraman is an emerging leader in orthopaedic outcomes research, with a focused expertise in computer-assisted and robotic-assisted arthroplasty. Her work critically evaluates whether advanced surgical technologies—such as navigation and robotic systems for total hip and knee arthroplasty—translate into meaningful improvements for patients. In a landmark 2024 systematic review, she demonstrated that while these technologies enhance implant positioning, the resulting patient-reported outcome measures (PROMs) frequently fail to reach clinically important thresholds, challenging assumptions about their routine superiority. Her 2023 study on a handheld image-free robotic system for total knee arthroplasty provided early evidence on clinical, radiographic, and patient-reported outcomes, while a subsequent 2024 investigation revealed that robotic-assisted total knee arthroplasty tends to produce smaller femoral components and larger tibial baseplates compared to manual techniques—a finding with direct implications for implant sizing and surgical planning. Though early in her career, Rajahraman’s work is already shaping evidence-based discussions on the value of surgical robotics, earning citations that underscore its relevance to surgeons and researchers seeking to balance technological promise with patient-centered outcomes.
