Lubrication Effect of Polyvinyl Alcohol/Polyethylene Glycol Gel for Artificial Joints
نویسندگان
چکیده
One of the most common problems encountered by patients using artificial joints is high wear rate. In this study, a polyvinyl alcohol/polyethylene glycol (PVA/PEG) gel was prepared through cross-linking reaction between alcohol (PVA) and polyethylene (PEG) solutions. This can lubricate joints, thereby lowering their coefficient friction (COF) increasing service life. Various techniques, such as Fourier transform infrared spectroscopy, X-ray diffraction, Raman spectra, photon thermogravimetric analyses, were used to analyze structure synthetic gel. The tribological results indicated that gel’s lubrication effect optimum when it contained PVA (10 wt%) PEG (15 wt%). An average COF 0.05 obtained under load 10 N at speed 1.0 cm/s. addition, rate reduced in comparison distilled water. Furthermore, biological tests proved PVA/PEG highly biocompatible. Thus, study introduces novel technique prepare gels improve performance joints.

Lubrication and wear modelling of artificial hip joints: A review
The tribological performance of artificial hip joints is a critical issue for their success, because adverse tissue reaction to wear debris causes loosening and failure. Many studies on wear and lubrication of hip prostheses have been published in the last 10 years, mostly on experimental tests. Theoretical/ numerical models have been proposed for investigating geometrical and material paramete...
متن کاملSynovial Joints and Lubrication mechanisms
Synovial joints form the most important feature of the human body as they represent the centers of the most essential and basic activity in the human beings, which is motion. A synovial joint can be described as a load carrying system consisting of two mating bones with tangential and /or normal motions. The bone ends, which are usually spherical in appearance, are covered with a soft sponge li...
متن کاملTowards a New Model for Synovial Fluid Lubrication and Wear of Artificial Joints
Surface wear of metal-on-metal (MoM) hip joints is an ongoing problem that can result in the formation of nano-wear particles and premature failure of the prosthesis. Wear is essentially controlled by the properties of the synovial lubricating film and the nature of the articulating surface. The interfacial film thickness formed within the loaded contact zone during the gait cycle is the most i...
متن کاملModes of lubrication in human hip joints.
Cadaveric hip joints were tested in a hip function simulator which subjected the femoral head to a cycle of loading and oscillation similar to that experienced during walking and measured the frictional torque transmitted to the acetabulum. Silicone fluids with viscosities from 10-2 Pa s (pascal second) to 30 Pa s were used as lubricants and the transition from mixed to full fluid film lubricat...
متن کاملSupramolecular synergy in the boundary lubrication of synovial joints
Hyaluronan, lubricin and phospholipids, molecules ubiquitous in synovial joints, such as hips and knees, have separately been invoked as the lubricants responsible for the remarkable lubrication of articular cartilage; but alone, these molecules cannot explain the extremely low friction at the high pressures of such joints. We find that surface-anchored hyaluronan molecules complex synergistica...
