Abstract

This article focuses on comparing revision rates following total hip replacement (THR) in younger Australian patients (under 55 years) with primary diagnoses of avascular necrosis (AVN) versus osteoarthritis. Using data from the Australian Orthopaedic Association National Joint Replacement Registry from 1999 to 2022, the study found that patients with AVN had a higher overall revision rate, particularly due to early postoperative infections and dislocation/instability, compared to those with osteoarthritis. No significant differences were observed in revisions for implant loosening or periprosthetic fracture between the groups. Despite the increased revision risk in AVN patients, 10-year implant survival rates were high (approximately 94%), supporting THR as a viable treatment option for younger patients with AVN.
