Saint Josephs’s Medical Center Welcomes New Orthopedic Surgical Team and ARTHUR

As part of its new orthopedic practice, Saint Joseph’s Medical Center introduced its new state-of-the art surgical robot. Called 

ARTHUR, the robot uses Stryker’s Mako™ Robotic-Arm Assisted Technology to perform robotic assisted orthopedic surgery for partial and total knee replacement and total hip replacement procedures. 

ARTHUR is part of the hospital’s ongoing investment in enhancing its orthopedic services with Southern Westchester Orthopedics and Sports Medicine joining Saint Joseph’s Medical Practice, PC. The new orthopedic practice is led by renowned orthopedic surgeons, David Lent, MD, FAAOS, and Eric Spencer, MD, FAAOS. 

ARTHUR stands for Advanced Robotic Technology for Human Ultra-precise orthopedic Reconstruction. The robot was named through a contest held by Saint Joseph’s Medical Center which attracted hundreds of entries from area residents. The winning entry was from Thomas Melillo, Director, Communications and Public Relations, Saint Joseph’s Medical Center

Yonkers Mayor Mike Spano was on hand March 13 to welcome the hospital’s new orthopedic team and to meet ARTHUR. 

Mako Robotic-Arm Assisted Technology is an innovative solution that combines robotic precision with the skill and expertise of orthopedic surgeons. This state-of-the-art technology allows for personalized surgical plans based on the patient’s unique anatomy, resulting in improved outcomes, faster recovery times, and enhanced patient satisfaction.

With the Mako system, patients requiring orthopedic surgery undergo a pre-surgical CT scan to create a precise 3D model of their joint. This serves as the foundation for the development of a customized surgical plan tailored to the individual patient. During the operation, the surgeon guides the robotic arm, following the pre-operative plan and making real-time adjustments as necessary. The system ensures precision within predetermined boundaries, minimizing the risk of complications commonly associated with traditional joint replacements.
