Age-based Cut-off Point as Methodological Approach in Search for Differences in Mortality and Revision for Fixation Type: Cemented Versus Uncemented Total Hip Arthroplasty

Leiden University Medical Center·observational·Posted Nov 4, 2021·Updated Nov 15, 2021

In Brief

An observational study evaluating Cemented THA and Unemented THA for Hip Osteoarthritis. Completed, enrolled 43,789 participants across 1 site.

Detailed Summary

The goal of this study is to apply the regression discontinuity design (RD) methodology on arthroplasty registry data. The investigators aim to use an age-based cut-off for fixation type choice and estimate the causal effect of fixation type on short term mortality and revision, using a fuzzy regression discontinuity design.
