Abstract Articular cartilage (AC) is a specialized connective tissue able to provide low‐friction gliding surface supporting shock‐absorption, reducing stresses, and guaranteeing wear‐resistance thanks its structure mechanical lubrication properties. Being an avascular tissue, AC has limited ability heal defects. Nowadays, conventional strategies show several limitations, which results in ineffective restoration of chondral Several engineering approaches have been proposed restore the AC's...
Crosslinked vitamin-E-stabilized polyethylene acetabular cups were compared with both commercially available conventional and custom-crosslinked in terms of wear behavior, a hip joint simulator for five millions cycles, using bovine calf serum as lubricant. We correlated the experiments results chemical characterization investigated materials: Fourier transformed infrared (FTIR) spectroscopic analyses, differential scanning calorimetry, crosslink density measurements used to assess...
The hip joint replacement is one of the most successful orthopedic surgical procedures although it involves challenges to overcome. patient group undergoing total arthroplasty now includes younger and more active patients who require a broad range motion longer service lifetime for joint. It well known that wear tests have long duration they are very expensive, thus studying effects geometry, loading, or alignment perturbations may be performed by Finite Element Analysis. aim study was...
In biomechanics and orthopedics, finite element modelling allows simulating complex problems, in the last few years, it has been widely used many applications, also field of biotribology. As is known, one crucial point FEM (finite model) discretization physical domain, this procedure called meshing. A well-designed mesh necessary order to achieve accurate results with an acceptable computational effort. The aim work test a model simulate dry frictionless contact conditions hip joint...
Wear of polyethylene acetabular components hip implants is a significant clinical problem. In prosthetic surgery, wear identified as factor that limits the life implant; it known production debris can cause adverse tissue reactions may lead to extensive bone loss around implant, and consequently loosening fixation. A new class so-called Diamond-Like Carbon coatings, applied titanium femoral heads was compared ceramic metallic in terms behavior against UHMWPE using joint simulator with bovine...
Abstract The use of ceramic‐on‐ceramic (alumina‐ and zirconia‐based) couplings in hip joint prostheses has been reported to produce lower wear rates than other combinations (i.e., metal‐on‐polyethylene ceramic‐on‐polyethylene). addition zirconia into an alumina matrix (zirconia‐toughened alumina, ZTA) result enhancement flexural strength, fracture toughness, fatigue resistance. development new processing routes nonaqueous media allowed obtain high‐density ZTA nanocomposites with a very...
Various studies report a weak correlation between the average surface roughness R of metallic ballheads and observed wear rate polyethylene cups coupled to them. The aim this study is verify, with controlled in vitro experiments, whether other parameters such as total t , skewness sk are better predictors when heads present conditioning that varies substantially from specimen specimen, usually case retrieved specimens. Twelve CoCrMo (cobalt-chromium-molybdenum) were intentionally damaged...
