DirectionalSafety and Complications Interpretation
While these statistics soberly remind us that modern surgery is a profoundly human endeavor—brilliant but never perfectly safe—they also chart the critical map of risks we must navigate to continually improve.

1VTE prophylaxis failure rate 0.9% in hip/knee replacements 2019, category: Safety and Complications
VerifiedSafety and Complications, source url: https://orthoinfo.aaos.org/en/recovery/total-hip-replacement/ Interpretation
While a 0.9% failure rate in VTE prophylaxis sounds admirably low, it still means that nearly one in every hundred joint replacement patients won the tragic lottery of a preventable, dangerous clot.
