Regression Discontinuity Design Search for Differences in Mortality and Revision for Fixation Type of THA

NCT05108155 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 43789

Last updated 2021-11-15

No results posted yet for this study

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.

Conditions

  • Hip Osteoarthritis

Interventions

PROCEDURE

Cemented THA

THA with cement fixation

PROCEDURE
