Patient function after a posterior stabilizing total knee arthroplasty: cam–post engagement and knee kinematics

Computational modeling of the reconstructed knee is an important tool in designing components for maximum functionality and life. Utilization of boundary conditions consistent with in vivo gait loading in such models enables predictions of knee kinematics and polyethylene damage [1–4], which can then be used to optimize component design. Several recent clinical studies have focused on complications associated with the patellofemoral joint [5–6], highlighting the need to better understand the mechanics of this compartment of total knee arthroplasty (TKA). This study utilizes a computational model to characterize the impact of gait loading on the mechanics of the patella in TKA.

AbstractTotal knee arthroplasty (TKA) is a highly successful operation that improves patients' quality of life and functionality. Yet, up to 20% of TKA patients remain unsatisfied with their clinical result. Robotic TKA has gained increased attention and popularity as a means of improving patient satisfaction. The promise of robotic-assisted TKA is that it provides a surgeon with a tool that accurately executes bone cuts according to presurgical planning, as well as provides the surgeon with intraoperative feedback helpful for restoring knee kinematics and soft tissue balance. Several systems are now available, each with their own advantages and disadvantages. Evidence that the use of robotics will lead to improved implant survival, function, and patient-reported outcomes is slowly being accumulated, but this has not been clearly proven to date. Recent literature does show that the use of robotics during TKA is not associated with increased surgical time or complications. The goal of this review is to provide an objective assessment of the evidence surrounding robotic technology for TKA.
