Wear of moderately cross-linked polyethylene fixed bearing knee replacements
Cross-linked polyethylene has been explored as an alternative to conventional polyethylene in total joint replacement in order to reduce wear volume and decrease failure through polyethylene wear debris induced osteolysis [1]. Due to the demands of a total knee replacement, moderately cross-linked polyethylene is recommended to retain mechanical properties [2]. This study aims to investigate th...
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 کاملPolyethylene wear in uncemented knee replacements.
Isolated wear of the polyethylene tibial component led to failure in five of a series of 108 uncemented porous-coated knee replacements. The clinical features included pain, effusion and instability with progressive varus deformity. In all cases there was extensive wear on the medial side of the polyethylene surface of the prosthesis. The mechanism of such wear is complex, being due in part to ...
متن کاملSimulating Wear On Total Knee Replacements
Wear on total knee replacements (TKRs) is an important criterion for their performance characteristics. Numerical simulations of such wear has seen increasing attention over the last years. They have the potential to be much faster and less expensive than the in vitro tests in use today. While it is unlikely that in silico tests will replace actual physical tests in the foreseeable future, a ju...
متن کاملIn-vitro wear of fixed and mobile bearing unicompartmental knee replacements
Introduction Unicompartmental knee replacement (UKR) is an increasingly popular surgical intervention for the treatment of osteoarthritis, involving the replacement of only one compartment of the natural knee. There is promising clinical literature which shows excellent long term survivorship of both fixed and mobile bearing UKR, with fixed bearings showing more consistent long-term performance...
