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 .
A randomised, controlled trial of cemented versus cementless press-fit condylar total knee replacement. Ten-year survival analysis.
We have carried out a long-term survival analysis of a prospect i ve , r and omised trial comparing cemented with cementless fixation of press-fit condylar primary total knee replacements . A consecutive series of 501 replacements received either cemented ( 219 patients , 277 implants ) or cementless ( 177 patients , 224 implants ) fixation .  The patients were contacted at a mean follow-up of 7.4 years ( 2.7 to 13.0 ) to establish the rate of survival of the implant . The ten-year survival was compared using life-table and Cox 's proportional hazard analysis . No patient was lost to follow-up . The survival at ten years was 95.3 % ( 95 % CI 90.3 to 97.8 ) and 95.6 % ( 95 % CI 89.5 to 98.2 ) in the cemented and cementless groups , respectively . The hazard ratio for failure in cemented compared with cementless prostheses was 0.97 ( 95 % CI 0.36 to 2.6 ) . A comparison of the clinical outcome at ten years in 80 knees showed no difference between the two groups . The survival of the press-fit condylar total knee replacement at ten years is good irrespective of the method of fixation and brings into question the use of more expensive cementless implants
