Abstract
Background
The aim was to describe temporal changes and associated changes in patient demographics and surgical variables, revision rate and factors associated with revision of primary hinge knee arthroplasty (HKA) in the UK.
Methods
National Joint Registry data for England, Wales, Northern Ireland and Isle of Mann was used to examine the temporal trends in patient demographics, surgical factors and indications for primary HKA usage over a 16-year (2003 to 2018) period and associated risk factors for revision.
Results
There were 4921 patient episodes with a median follow up of 5.5 (range 0 to 16.3) years. The median age was 75years and the majority were female (72.9%). There was a tenfold increase in the use of HKA (p < 0.001), with an increased relative usage in female patients (p = 0.010), but no significant changes in age (p = 0.484) or BMI (p = 0.781). There were 227 revisions performed at a median of 695days. The overall unadjusted probabilities of revision at 1, 5 and 10 years were 1.5% (95% confidence intervals (CI) 1.1to1.8), 4.4% (95%CI 3.7 to 5.0) and 6.4% (95%CI 5.5 to 7.3), respectively. Cox proportional hazard analysis demonstrated younger age (p < 0.01), male sex (hazard ratio (HR) 1.43, p < 0.01), morbid obesity (HR 2.31, p = 0.022) or previous trauma as the indication (HR 1.48, p = 0.025) were associated with an increased risk of revision.
Conclusion
There was an increase in the use of HKA with increased uptake among female patients. The revision rate was a 6.4% at 10 years, however, younger age, male sex, morbid obesity or previous trauma were associated with an increased risk of revision.
