A prosthetic knee with an artificial ACL/PCL. The prosthetic knee includes a femoral component and a tibial component. The artificial ACL/PCL connects the femoral component and the tibial component and includes an anterior cruciate ligament portion connecting an anterior anchor point on the tibial component to a posterior anchor point on the femoral component, and a posterior cruciate ligament portion connecting a posterior anchor point on the tibial component to an anterior anchor point on the femoral component. The artificial ligament may be provided as single length of material and may be pre-assembled into an ACL/PCL module having portions that may be inserted into at least one of the femoral component or the tibial component. A system is also provided for total knee replacement that includes a selection of femoral components, tibial components, and one or more ACL/PCL modules of varying sizes.
