Wear Analysis of Second-generation Highly Cross-Linked Polyethylene in Primary Total Hip Arthroplasty.
A major limiting factor in the longevity of total hip replacement is the wear rate of the hip bearing. As manufacturing technology has improved during the past several decades, much attention has been focused on developing newer generations of polyethylene that have lower rates of wear while minimizing free radical formation and subsequent osteolysis. The turning point for the manufacture of po...
متن کاملRim cracking of the cross-linked longevity polyethylene acetabular liner after total hip arthroplasty.
BACKGROUND Studies have suggested that cross-linked polyethylene bearings reduce wear rates from 40% to 100% compared with conventional polyethylene. However, the reduced mechanical properties of highly cross-linked polyethylene have the potential to be a limiting factor in device performance. We reviewed a series of retrieved acetabular liners with a fracture of the superior rim to assess the ...
متن کاملWear of Highly Cross-linked Polyethylene against Cobalt Chrome and Ceramic Femoral Heads
+*Jennings, L M; *Galvin, A L; *Fisher J +Institute of Medical & Biological Engineering, Leeds, UK [email protected] Introduction There is increasing interest in the coupling of highly cross-linked polyethylene with large diameter heads in the hip, due to the reported lower wear characteristics of highly cross-linked polyethylene compared to conventional polyethylene [1, 2, 3]. Further, ...
متن کاملIncarcerated fracture fragments of Longevity polyethylene liners after total hip arthroplasty
Highly cross-linked polyethylene liners are widely used in total hip arthroplasty because they experience lower wear rates than conventional polyethylene liners. However, the cross-linking process does decrease the resistance of polyethylene to fatigue failure and fracture. This report describes 2 cases of highly cross-linked polyethylene liner fracture occurring in association with hip disloca...
متن کاملSequentially Annealed Highly Cross-linked Polyethylene Reduced In Vivo Wear Particle Generation In TKA
Introduction: Polyethylene wear particles induce macrophages to release cytokines, which can lead to osteolysis and aseptic loosening of total joint prostheses. The generation of polyethylene wear particles is one of the most important factors that affect the midterm and long-term clinical results associated with total knee arthroplasty (TKA). Therefore, to achieve better long-term results for ...
