They can potentially be used to streamline post-THA follow-up to high-risk patients. We aimed to determine whether the long-term revision risk in THA relates to patient-reported measures at 2 and 5 years. Methods In a single-institution cohort of primary THA procedures, we examined the association between 2-year and 5-year pain and Mayo Hip Scores and the risk of revision. Results The absolute scores at 2 and 5 years were both significantly associated with the risk of revisions. Every 10-unit decline in the 2-year Mayo Hip Score <60 was associated with a significant 50% increase in the risk of revision (hazard ratio, 1.5 per 10 units; 95% confidence interval, 1.3-1.8). Similarly, every 10-unit decline in the 5-year Mayo Hip Score <60 was associated with almost doubling of the risk of revision (hazard ratio, 1.9 per 10 units; 95% confidence interval, 1.7-2.1). Conclusion We conclude that patient-reported outcomes in THA have prognostic importance and can be taken into account when planning frequency of aftercare. This will improve the efficiency of follow-up in large registry-based follow-up efforts.
