Total knee arthroplasty (TKA) is a common treatment for osteoarthritis to reduce pain and improve function. Preserving the posterior cruciate ligament (PCL) or not depends on the condition and quality of the PCL. In case of preserving the PCL, cruciate-retaining (CR) inserts can be used, with their several advantages of keeping the PCL intact. In case of substituting the PCL, a new insert design is introduced (anterior-stabilizing (AS) insert), which has several advantages over the traditionally used posterior-stabilizing (PS) insert, like preserving bone, reducing operative time and limiting wear. However, little is known about the long-term survival of the AS insert. In this retrospective cohort study, we will investigate the long-term survival of TKA with a CR insert compared to an AS insert using the Dutch Arthroplasty Register by comparing the revision rate and the reasons for revision.
