Study on Polyvinyl Alcohol Hydrogel Materials for Improving the Performance of Artificial Articular Cartilage

Polyvinyl alcohol hydrogel has compatibility and biomechanical properties of human articular cartilage similar and good biological. The implantation in the human body can replace part of articular cartilage, which plays the role of bearing and alleviate the impact force. It has the prospect of clinical application. This paper introduces the research progress of polyvinyl alcohol hydro-gel materials. And compared with the characteristics of articular cartilage, clarify the possibility of repair of articular cartilage defects of the materials.
