This study investigated patient reported outcomes, and associations with improvement in quality of life 12-months after total hip arthroplasty (THA). Materials and methods: Adults (n = 433) undergoing THA for osteoarthritis between January 2017 and October 2020 in a large publicly funded tertiary hospital in New Zealand. Participants completed patient reported outcome measures of pain, function and quality of life (QOL) preoperatively, 6- and 12-months following THA. Clinically significant changes in domains of pain and function were associated with improved QOL, even when pre-operation scores were controlled for. The largest gains in all three domains occurred in the pre-to 6-month post-operation period. Baseline demographic variables such as gender and comorbidities were not associated with change in QOL pre-to post-operation. However, although modest, age at surgery was negatively correlated with change in QOL. THA contributes to substantial improvements in QOL, pain and function outcomes, and although possibly tempered by age, these relationships are likely to be inter-related and mutually reinforcing. Future QOL outcomes research should also consider the impacts on QOL improvement of other aspects of functioning such as psychological and social wellbeing.
