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 .
Comparison of mobile-bearing and fixed-bearing total knee arthroplasty: a prospective randomized study.
The purpose of this prospect i ve r and omized study was to compare the postoperative recovery and early results of 2 groups of patients undergoing total knee arthroplasty : 107 patients received an established fixed-bearing posterior-stabilized prosthesis ( Legacy Posterior Stabilized [ LPS ] ) , and 103 patients the meniscal-bearing prosthesis ( Meniscal Bearing Knee [ MBK ] ) .  Surgical procedures were the same for both groups except for posterior cruciate ligament management , which was sacrificed in the LPS group and spared but completely released from the tibia in the MBK group . At an average follow-up of 36 months , knee , function , and patellar scores were comparable in both groups . The LPS group showed a significantly higher maximum flexion than the MBK group ( 112 degrees vs 108 degrees ) . Using a fixed-bearing or a mobile-bearing design did not seem to influence the short-term recovery and early results after knee arthroplasty .
