About
Perry L. Lim is a rising orthopaedic outcomes researcher whose work is reshaping how we evaluate the value of robotic assistance in joint arthroplasty. His research centers on three key areas: the clinical effectiveness of robotic versus manual total knee and hip arthroplasty, the use of minimal clinically important difference (MCID) as a rigorous outcome metric, and value-based cost-effectiveness analysis using time-driven activity-based costing (TDABC). Lim’s major contributions include demonstrating that robotic-assisted unicompartmental knee arthroplasty (UKA) achieves MCID faster than manual techniques, and that robotic total hip arthroplasty increases the likelihood of meaningful improvement—findings from a propensity-matched analysis of 1,364 procedures. His 2024 paper on robotic versus manual UKA has already garnered 11 citations, and his 2025 value analysis of UKA versus total knee arthroplasty provides a novel patient-level cost-effectiveness framework. Lim has also authored commentaries and comparative recovery-time studies, cementing his role as a thoughtful voice in the debate over surgical technology’s return on investment. For students and researchers, his work exemplifies how combining patient-reported outcomes with advanced costing methods can guide evidence-based, value-driven orthopaedic care.
