Similar early mortality risk after cemented compared with cementless total hip arthroplasty for primary osteoarthritis: data from 188606 surgeries in the Nordic Arthroplasty Register Association database

摘要

Background and purpose — Current literature indicates no difference in 90-day mortality after cemented compared with cementless total hip arthroplasty (THA). However, previous studies are hampered by potential selection bias and suboptimal adjustment for comorbidity confounding. Therefore, we examined the comorbidity-adjusted mortality up to 90 days after cemented compared with cementless THA performed due to osteoarthritis.
