Evaluating In-Hospital Safety and Perioperative Costs of Total Hip Arthroplasty in Super-Elderly Patients: A Nationwide Propensity Score-Matched Analysis in Japan.

ABSTRACT: Background: This study aimed to evaluate short-term outcomes, including in-hospital complications, mortality, and medical costs, after total hip arthroplasty (THA) in super-elderly patients aged ≥85 years compared with elderly patients aged 70-84 years, using a nationwide database in Japan. Materials and Methods: We conducted a retrospective cohort study using the Japanese Diagnosis Procedure Combination (DPC) database from 2011 to 2023.
