Comparison of in vivo wear between polyethylene liners articulating with ceramic and cobalt-chrome femoral heads.
At yearly intervals we compared the radiological wear characteristics of 81 alumina ceramic femoral heads with a well-matched group of 43 cobalt-chrome femoral heads. Using a computer-assisted measurement system we assessed two-dimensional penetration of the head into the polyethylene liner. We used linear regression analysis of temporal data of the penetration of the head to calculate the true...
متن کاملComparison of the risk of revision in cementless total hip arthroplasty with ceramic-on-ceramic and metal-on-polyethylene bearings
BACKGROUND AND PURPOSE Ceramic-on-ceramic (CoC) bearings were introduced in total hip arthroplasty (THA) to reduce problems related to polyethylene wear. We compared the 9-year revision risk for cementless CoC THA and for cementless metal-on-polyethylene (MoP) THA. PATIENTS AND METHODS In this prospective, population-based study from the Danish Hip Arthroplasty Registry, we identified all the...
متن کاملWear of highly crosslinked polyethylene acetabular components
BACKGROUND AND PURPOSE Wear rates of highly crosslinked polyethylene (XLPE) acetabular components have varied considerably between different published studies. This variation is in part due to the different techniques used to measure wear and to the errors inherent in measuring the relatively low amounts of wear in XLPE bearings. We undertook a scoping review of studies that have examined the i...
متن کاملIs There a Benefit to Highly Crosslinked Polyethylene in Posterior-stabilized Total Knee Arthroplasty? A Randomized Trial.
BACKGROUND Polyethylene wear and osteolysis remain a concern with the use of modular, fixed-bearing total knee arthroplasty (TKA). A variety of highly crosslinked polyethylenes (XLPs) have been introduced to address this problem, but there are few data on the results and complications of this polyethylene in posterior-stabilized knee prostheses. QUESTIONS/PURPOSES In a randomized prospective ...
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, ...
