Mobile- vs. fixed-bearing total knee replacement
BACKGROUND AND PURPOSE It is unclear whether mobile-bearing (MB) total knee arthroplasties reduce the risk of tibial component loosening compared to fixed-bearing (FB) designs. This randomized study investigated implant migration, periprosthetic bone mineral density (BMD), and patient-reported outcomes (Oxford knee score)-all at 2 years-for the P.F.C. Sigma Cruciate Retaining total knee arthrop...
متن کاملWear Comparison of Fixed vs. Mobile Bearing Total Knee Replacements
INTRODUCTION: The debate between fixed-bearing and mobile-bearing systems continues due to the lack of clinical evidence showing survivorship of one to be superior to the other [1,2]. Delport et al report similar tibiofemoral kinematic patterns with respect to axial rotation during flexion and also femorotibial translation [3]. Conversely, Huang et al show a significant difference between the t...
متن کاملFixed or mobile-bearing total knee arthroplasty
Fixed and mobile-bearing in total knee arthroplasty are still discussed controversially. In this article, biomechanical and clinical aspects in both fixed and mobile-bearing designs were reviewed. In biomechanical aspect, the mobile-bearing design has proved to provide less tibiofemoral contact stresses under tibiofemoral malalignment conditions. It also provides less wear rate in in-vitro simu...
متن کاملFixed- 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 randomised to undergo TKA using a fixed- or mobile-bearing prosthesis. Patients w...
متن کاملEarly aseptic loosening of a mobile-bearing total knee replacement
Background and purpose - Registry-based studies have reported an increased risk of aseptic tibial loosening for the cemented Low Contact Stress (LCS) total knee replacement compared with other cemented designs; however, the reasons for this have not been established. We made a retrieval analysis with the aim of identifying the failure mechanism. Patients and methods - We collected implants, cem...
