Squeaking friction phenomena in ceramic hip endoprosthesis: Modeling and experimental validation
Mechanical Systems and Signal Processing(2015)
摘要
The modern evolution of ceramic bearing surfaces for total hip arthroplasty has allowed longer implant longevity with lower amounts of osteolysis. It has been applied to younger patient expecting improved survivorship compared with traditional bearing surfaces. However, the phenomenon of an audible squeaking produced by implants during daily activities is reported as an annoying complication for patients.
