Gender Differences in Wear Rates for 28 versus 32 millimeter Ceramic Femoral Heads on Modern Highly Cross-linked Polyethylene at Midterm Follow-up in Young Patients Undergoing Total Hip Arthroplasty

摘要

BackgroundWe report on the midterm linear and volumetric wear of highly cross-linked polyethylene (HXLPE) and survivorship of two prospective young THA cohorts that differed by the size of ceramic femoral head used: 28 vs. 32 millimeters.
