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 .
[Prospective randomized comparative study of early functional outcome of 2 knee joint endoprosthesis systems--rotation plateau versus fixed polyethylene inlay].
AIM Different systems are used for total knee arthroplasty ( TKA ) . Compared were a press-fit femur condyle replacement system with fixed tibial PE-inlay versus a rotating tibia component system with an emphasis on the early functional results . METHOD Patient selection and the use of the  Knee Society Score for this r and omized and prospect i ve study were based on the directives for TKA of the german Society for Orthopaedic and Trauma Surgery ( DGOT ) . We examined the patients post-operatively after 1 week , 2 weeks , 6 weeks , 3 months , 6 months , and 1 year . RESULTS After 6 weeks an increase of the total knee score could be seen in both groups . The total knee score of the rotating tibia component  increased from 93.96 pre-operatively to 113.57 after 6 weeks , to 139.82 after 3 months , to 154.32 after 6 months , and to 159.65 after one year . The total score with the fixed PE-inlay increased from 79.75 to 111.5 after 6 weeks , to 128.25 after 3 months , to 134.08 after 6 months , and to 130.08 after one year . CONCLUSION After 6 weeks the implant with the rotating tibia component showed a lasting higher score as compared to the implant with a fixed PE-inlay component using the same early rehabilitation and mobilization techniques
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 .
