This paper reviews the recent advancements in computational modelling of lubrication hip and knee joint replacements, especially those concerning Professor Duncan Dowson’s contribution. The review starts with development five key parameters that appeared pioneered Hamrock–Dowson formula. Then, theory approaches for mixed which artificial replacements operate are reviewed. We also discuss curren...
