Abstract

Introduction

Our aim was to investigate trends in the incidence rate and main indication for revision knee replacement (rKR) over the past 15 years in the UK.

Methodology

Cross-sectional study from 2006 - 2020 using data from the National Joint Registry (NJR). Crude incidence rates were calculated using population statistics from the Office for National Statistics.

Results

Annual total counts of rKR increased from 2743 procedures in 2006 to 6819 procedures in 2019 (149% increase). The incidence rate of rKR increased from 6.3 per 100,000 adults in 2006 (95% CI 6.1 to 6.5) to 14 per 100,000 adults in 2019 (95% CI 14 to 14). Annual increases in the incidence rate of rKR became smaller over the study period. The incidence of rKR was highest in patients aged 70–79 years (50 per 100,000 adults [95% CI 48 to 52]). Aseptic loosening was the most frequent indication for rKR overall (20.5% procedures). However, rKR for aseptic loosening peaked in 2012 and subsequently decreased. rKR for infection increased incrementally over the study period to become the most frequent indication for rKR in 2019 (2.7 per 100,000 adults [95% CI 2.6 to 2.9]). Infection accounted for 17.2% first linked rKR, 36.7% second linked rKR and 50.7% third or more linked rKR.

Conclusion

Recent trends suggest slowing of the rate of increase in the incidence of rKR. Infection is now the most common indication for rKR, following recent decreases in rKR for aseptic loosening. Infection was prevalent in re-revision KR procedures.
