A Novel Robotic Technique for Mapping Patellofemoral Kinematics in Total Knee Arthroplasty
Computer assistance has significantly improved precision in total knee arthroplasty (TKA). Current robotic systems address tibiofemoral kinematics, ignoring the patellofemoral joint. This described TKA technique allows assessment and adjustment of patellofemoral kinematics. Reproducible landmarks on...

| description | Computer assistance has significantly improved precision in total knee arthroplasty (TKA). Current robotic systems address tibiofemoral kinematics, ignoring the patellofemoral joint. This described TKA technique allows assessment and adjustment of patellofemoral kinematics. Reproducible landmarks on the tibial tubercle, trochlea, and patella are defined. With the “Special Point” function of the CORI surgical system, arcs of points are recorded dynamically. This records trochlear groove translation, patellar tracking, patellar tilt, and tibial tubercle rotation. During implant trials, special points are recollected to determine how these four parameters have changed compared to the native knee. Component adjustments can be made to optimize patellofemoral kinematics without compromising tibiofemoral balance. This may be a tool to mitigate patellofemoral maltracking and may improve TKA outcomes. Further studies are required to investigate outcomes. |
