Andrew I. Spitzer

About

Andrew I. Spitzer is a leading orthopedic surgeon and researcher whose work centers on advancing surgical outcomes through technology, particularly in total knee arthroplasty (TKA) and postoperative recovery. His major contributions lie in two key areas: the use of robotic-assisted systems to improve surgical precision and patient function, and the application of wearable activity monitors to transform postoperative care. His highly cited 2019 study (154 citations) on wearable activity monitors demonstrated that objective measurement of early ambulation after major surgery can predict length of stay, offering hospitals a data-driven tool to enhance recovery protocols. In robotic-assisted TKA, his 2024 retrospective study (20 citations) showed that robotic assistance reduces the need for soft-tissue releases, leading to improved functional outcomes. He has also investigated image-free robotic systems, such as the VELYS™, finding they can improve Knee Society Function Scores compared to manual instrumentation. Spitzer’s work bridges cutting-edge technology and practical clinical application, providing evidence that helps surgeons adopt innovations that directly benefit patient mobility and recovery.
