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 .
Fixed- versus Mobile-Bearing Total Knee Arthroplasty in Indian Patients
Purpose . To compare the mid-term clinical outcomes in Indian patients after total knee arthroplasty ( TKA ) using a fixed- or mobile-bearing prosthesis . Methods . 120 consecutive patients ( 50 men and 70 women ) aged 55 to 76 ( mean , 63 ) years who had arthritis of the knee with similar deformity and range of motion were r and omised to undergo TKA using a fixed- or mobile-bearing prosthesis .  Patients with mediolateral instability and infective arthritis were excluded .  Knee Society knee and functional scores , range of motion , and the presence of flexion contracture were assessed . Results . The mean follow-up duration was 3.5 ( range , 1–4.6 ) years . The mid-term outcome of the 2 groups was comparable . One patient with a mobile-bearing prosthesis had recurrent dislocation at postoperative week 2 , owing to iatrogenic medial collateral ligament injury . Conclusion . Long-term studies of both functional and radiological outcomes are needed to determine the indications for fixed- versus mobile-bearing prostheses
