Finally , with use of a variety of vali date d measures , there was no difference between the two groups in terms of functional status at two , eight , and ten years , regardless of the measure used .
A less expensive all-polyethylene component as part of a total knee arthroplasty has results equivalent to those obtained with a cemented metal-backed tibial component .
BACKGROUND The cost of the implant as part of a total knee arthroplasty accounts for a substantial portion of the costs for the overall procedure : all-polyethylene tibial components cost considerably less than cemented metal-backed tibial components .
We performed a systematic review of the literature to determine whether the clinical results of lower-cost all-polyethylene tibial components were comparable with the results of a more expensive metal-backed tibial component .
Posterior-stabilized versus cruciate-retaining total knee arthroplasty: balancing the gap.
A prospect i ve , r and omized , double-blind trial was carried out to compare  cruciate-retaining ( CR ) and posterior-stabilized ( PS ) total knee arthroplasties ( TKAs ) . A total of 40 knees were r and omized to receive either a NexGen CR ( Zimmer , Warsaw , IN ) or a Legacy PS ( Zimmer , Warsaw , IN ) TKA . All knees were implanted with identical surgical technique , making sure to balance precisely the flexion-extension gaps before implantation of the components . At 2-year follow-up , there was no difference between the CR and the PS TKAs with respect to their Knee Society clinical , functional , and radiographic scores . These findings suggest that with careful attention to surgical technique and balancing the knee , orthopaedic surgeons should expect similar results whether they use a CR or PS TKA
