摘要：

Knee kinematics after total knee arthroplasty is dictated primarily by implant geometry and native soft tissue constraints. This study highlights the importance of a functioning posterior cruciate ligament in limiting excessive anteroposterior translation in a mobile bearing knee design that relies on native posterior cruciate ligament integrity and postarthroplasty tensioning for stability rather than any inherent mechanical design stability, such as anterior rails or stops.
