Polyethylene wear is related to patient-specific contact stress in THA.
Original language description
BACKGROUND: General numerical models of polyethylene wear and THA simulators suggest contact stresses influence wear. These models do not account for some patient-specific factors. Whether the relationship between patient-specific contact stress and wearapply in vivo is unclear. QUESTIONS/PURPOSES: We therefore determined whether (1) contact stress distribution at the prosthesis-cup interface and (2) hip geometry and cup inclination are related to wear in vivo. METHODS: We retrospectively reviewed theradiographs of 80 patients who had aseptic loosening of their THAs as determined by radiographic criteria. RESULTS: Linear penetration and volumetric wear correlated with peak contact stress.
