Wear 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 کاملA kinematic comparison of fixed- and mobile-bearing knee replacements.
Mobile-bearing posterior-stabilised knee replacements have been developed as an alternative to the standard fixed- and mobile-bearing designs. However, little is known about the in vivo kinematics of this new group of implants. We investigated 31 patients who had undergone a total knee replacement with a similar prosthetic design but with three different options: fixed-bearing posterior cruciat...
متن کاملMidterm Clinical and Radiographic Results of Mobile-Bearing Revision Total Knee Arthroplasty.
BACKGROUND Constrained implants are frequently required in revision total knee arthroplasty (TKA) and are associated with an increase in aseptic component loosening and damage or wear to the constraining mechanisms, compared with primary TKA. The purpose of the following study was to evaluate the midterm clinical and radiographic results including the incidence of bearing complications in a gro...
متن کاملMidterm results of mobile-bearing total knee arthroplasty in patients younger than 65 years.
This study evaluated 117 patients younger than 65 years (average, 56 years) in whom mobile-bearing total knee arthroplasties were inserted. All patellae were resurfaced with a mobile-bearing patella implant. Followup averaged 102 months (range, 60-171 months). The average knee score was 91 points, with a pain score of 27 points (possible 30 points). There were eight (7%) revision surgeries in t...
متن کاملMobile-bearing knee replacement: concepts and results.
In summary, if TKRs are to be performed in patients who are younger and more active than those who had the initial procedures in the 1970s and 1980s, better wear performance is imperative for long-term durability, especially if surgeons continue to consider the versatility associated with modular knee-replacement systems to be a necessity. At least with some designs, including the Oxford knee a...
