Overview Tibial forces in the medial and lateral compartments following calipered kinematically aligned (KA) total knee arthroplasty (TKA) are of high interest for two reasons. One reason is that knowledge…
Overview The fundamental principle of calipered kinematically aligned total knee arthroplasty (KA TKA) is to reproduce the flexion-extension axis of the prearthritic knee and to maintain the original collateral ligament…
Overview This chapter contains discussion and video links that assist the surgeon in performing calipered kinematically aligned (KA) total knee arthroplasty (TKA) with specific manual instruments, a verification worksheet, and…
Overview This chapter reviews the history of patient-specific instrumentation (PSI) and then outlines the design rationale, surgical techniques, and results seen in kinematically aligned (KA) total knee arthroplasty (TKA). The…
Introduction Computer-assisted surgery (CAS) or navigation has for the best part of two decades been the gold standard for accuracy and precision in total knee arthroplasty (TKA) in terms of…
Overview Robotic assistance was recently reintroduced in total knee arthroplasty (TKA) to improve surgical precision and to minimize errors. However, the technique stills focuses on mechanical alignment (MA) philosophies, with…
Overview This chapter reviews in vitro and in vivo differences in tibiofemoral kinematics between a low-conforming total knee arthroplasty (TKA) implanted with calipered kinematic alignment (KA) and the native knee….
Overview This chapter reviews differences between the morphology of the prosthetic trochlea for four different femoral components set in kinematic alignment (KA) and the native knee in the same femur-cartilage…
Overview • With calipered kinematic alignment (KA) technique, preoperative management and evaluation of the arthritic knee patient does not vary vastly from the standard evaluation. However, there are some subtle…
Overview This chapter discusses the research that is driving the change in philosophy from mechanical alignment (MA) to kinematic alignment (KA) in total knee arthroplasty (TKA). The first section discusses…
