In Vivo Assessment of Robotically Performed Total Knee Arthroplasty for Posterior-Cruciate and Bi-Cruciate Retaining and Substituting Implants

Description

The presentation discusses a study on the in vivo assessment of robotically performed total knee arthroplasty (TKA). The presenter expresses gratitude and shares their positive experience at the conference, before outlining the research. This study, undertaken alongside surgeons from the Chinese University of Hong Kong, investigates the efficacy of robotic systems in enhancing surgical precision and postoperative outcomes in knee surgery, particularly focusing on kinematic outcomes using fluoroscopy.



The research evaluates two types of robotic surgery systems: the cruciate-stabilized system and the cruciate-retaining system, comparing various Stryker triathlon implants. Through methods familiar to the audience, weight-bearing kinematics were measured during activities like deep knee bends, with an emphasis on comparing posterior rollback and axial rotation between different implant types.



Key findings indicate that the bi-cruciate systems achieve better lateral motion, mirroring non-implanted knees, although some implant designs still fall short of imitating the natural knee's motion. The trends observed suggest that while robotic assistance may enhance certain surgical aspects, it does not necessarily result in superior clinical outcomes compared to previous studies. The presentation concludes by emphasizing the need for further research, addressing the limitations of the study, and referring to additional sources.
