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 کاملPolyethylene wear in total hip arthroplasty.
Polyethylene wear increasingly has been blamed for osteolysis and granuloma formation after total joint arthroplasty. The authors evaluated the wear difference between bearing surfaces of stainless steel, cobalt chrome, and titanium alloy. They also compared cemented all-polyethylene molded cups with cemented metal-backed molded acetabular cups. These were compared with molded and machined poly...
متن کاملReview Article: Polyethylene wear and osteolysis in total hip arthroplasty.
Polyethylene wear has been accepted as a major cause of osteolysis in total hip arthroplasty. Submicron particles, which are secondary to abrasive wear, migrate into the effective joint space and stimulate a foreign-body response resulting in bone loss which is mainly mediated by macrophages. Diagnosis depends on serial radiographic evaluation and frequent follow-up. Polyethylene wear and osteo...
متن کاملFive-Year Experience of Vitamin E-Diffused Highly Cross-Linked Polyethylene Wear in Total Hip Arthroplasty Assessed by Radiostereometric Analysis.
BACKGROUND Vitamin E-diffused highly cross-linked polyethylene (VEPE) was developed to reduce oxidation without compromising mechanical strength. The purpose of this study was to evaluate VEPE in vivo using radiostereometric analysis (RSA) and patient-reported outcome measures (PROMs). METHODS Fifty-one hips were enrolled. Each patient received a VEPE liner, a porous titanium shell, and an un...
متن کاملIn Vivo Wear Particles of Annealed Highly Cross-Linked Polyethylene in Total Hip Arthropalsty
INTRODUCTION: Polyethylene wear particles induce cytokine release by macrophage, which leads to osteolysis and aseptic loosening in total joint arthroplasties. Generation of polyethylene wear particles is one of the most important factors that affecting mid-term and long-term results of total hip arthroplasty (THA). Therefore, to reduce wear generation and to achieve better long-term results of...
