Polyethylene Wear Debris From a Knee Simulator Model: Effect of Crosslinking and Counterface Material
INTRODUCION: Improved wear resistance of crosslinked UHMWPE has been well demonstrated in both hip and knee [1-4]. A reduction of 70% can be shown in knee simulators from conventional crosslinked tibial inserts (CXPE) gamma-irradiated at 3.5Mrad to 7Mrad highly crosslinked inserts (HXPE). Hip simulator models indicated that debris size decreased with increased crosslinking [5]. In the knee it h...
متن کاملUsing a surrogate contact pair to evaluate polyethylene wear in prosthetic knee joints.
With recent improvements to the properties of ultra-high molecular weight polyethylene (UHMWPE) used in joint replacements, prosthetic knee and hip longevity may extend beyond two decades. However, it is difficult and costly to replicate such a long in vivo lifetime using clinically relevant in vitro wear testing approaches such as walking gait joint simulators. We advance a wear test intermedi...
متن کاملInvestigation of Wear Behavior of Biopolymers for Total Knee Replacements Through Invitro Experimentation
The average life span of knee prosthesis used in Total Knee Replacement (TKR) is approximately 10 to 15 years. Literature indicates that the reasons for implant failures include wear, infection, instability, and stiffness. However, the majority of failures are due to wear and tear of the prosthesis. The most common biopolymer used in TKR is Ultra High Molecular Weight Polyethylene (UHMWPE). Pr...
متن کاملMobile or fixed unicompartmental knee prostheses? In-vitro wear assessments to solve this dilemma.
The unicompartmental knee prosthesis is an attractive alternative to total knee arthroplasty. Current UKP devices can be subdivided into two groups based on different design principles: fixed bearing knees, where the ultra-high molecular weight polyethylene meniscal component snap or press fits into the tibial tray, and mobile bearing designs which facilitate movement of the insert relative to ...
متن کاملA Low Conforming, Low Wear Solution in Fixed Bearing Total Knee Prostheses
Introduction: Ultra High Molecular Weight Polyethylene (PE) remains the primary bearing surface of choice in total knee replacements (TKR). Traditionally Archard’s Law is used to predict wear rates in hip and knee prostheses. This assumes that the volume of wear between two articulating surfaces is proportional to the applied load and sliding distance. However it has been shown that this is a s...
