Strategies for Improving the Prosthetic Trochlea Design Based on Differences in Trochlea Morphology Between Femoral Components Set in Kinematic and Mechanical Alignment 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 model. Trochlear morphology is described along the arc length of…

Strategies for Improving Implant Design Based on Differences in Tibiofemoral Kinematics of a Low-Conforming Total Knee Arthroplasty Implanted With Calipered Kinematic Alignment and the Native Knee

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. Kinematics are defined by laxities and resting positions of the…

Calipered Kinematic Alignment Total Knee Arthroplasty Performed With Specific Manual Instrumentation, Verification Checks, and a Decision Tree

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 a decision tree. The treatment of 4726 primary TKAs performed…
