## Abstract Squeaking is a cause for concern in total hip arthroplasty (THA). However, the definition of this sound remains vague. Our goals were to characterize spectrally the squeaking in vitro under lubricated conditions and to compare the in vitro frequencies to in vivo frequencies. Four patien
## Abstract Although impingement between the neck of the metallic stem and the ceramic liner has been suspected to be the cause of ceramic liner failure in ceramicβonβceramic total hip arthroplasty (THA), no report has directly demonstrated microscopic damage on ceramic liner. We performed 18 reope
## Abstract Hardβonβhard hip implants were thought as a solution to wear problems affecting polyethylene. Alumina ceramic and metal articulations are harder, biocompatible, and result in reduced wear and particles to the surrounding tissue. Alumina ceramic hip implants produce lower wear rates than
