## 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 Hard‐on‐hard 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
## Abstract Our 32 and 38 mm alumina ceramic‐on‐metal (COM) bearings were run in a hip simulator study for comparison with 32 mm metal‐on‐metal (MOM) controls. The 32 mm MOM bearings demonstrated an overall wear rate of 1.58 mm^3^/million cycles (Mc) that was comparable to previous simulator studie
## Abstract Hip resurfacing arthroplasty has become a popular alternative to conventional hip surgery. Surface replacements with bearing sizes of 55 mm (__n__ = 5) and 39 mm (__n__ = 5) were tested in a hip simulator for 15 million cycles (Mc). Wear debris was isolated from the serum lubricant and
