About

Cale Pagan is an emerging leader in orthopaedic surgery, with a focused research program on the optimization of robotic-assisted technology in total knee and hip arthroplasty. His work critically evaluates how modern surgical tools—particularly robotic arm assistance—affect clinical outcomes, surgical efficiency, and implant alignment. In his most cited paper, "Technology in Total Knee Arthroplasty in 2023" (33 citations), Pagan provides a comprehensive overview of the evolving technological landscape in joint replacement. He has made significant contributions to understanding the learning curve of robotic-assisted total knee arthroplasty (RA-TKA), demonstrating through cumulative sum analysis that operative times stabilize after a defined number of cases—a finding with direct implications for surgical training and OR scheduling. His comparative study on limb alignment found no difference between kinematic and mechanical alignment in robotic-assisted procedures, challenging assumptions about alignment philosophy. Pagan’s work also explores the relationship between tibial bone mineral density and patient factors like sex and age, informing fixation method choices. With a rapidly growing citation record and publications spanning 2023–2025, Pagan is shaping the evidence base for adopting robotic assistance in joint arthroplasty.
