Hip replacement has been performed for more than 70 years. So why don't we actually know how it's done around the world?
Approach. Fixation. Bearing surfaces. Positioning. Pre-op and post-op pathways. Practice varies wildly between countries, institutions, and individual surgeons - and in much of the world, registry data is incomplete, inconsistent, or missing entirely.
In this episode of the AHF Podcast, indefatigable host Joseph Schwab sits down with Irrum Afzal (Imperial College London) to talk about the Global Arthroplasty Practice Survey (GAPS) and the effort, with Professor Richard Field and an international group of surgeons, to map how hip replacement is really being performed worldwide.
Not how we assume it's done. Not how one registry captures it. How surgeons actually practice.
Some of what comes up:
→ Why anterior approach adoption runs ~1% in the UK but ~56% in the US -and what else might vary that we've never measured.
→ How "garbage in, garbage out" quietly undermines the registries we cite every day.
→ What a truly global picture of practice could change for patients.
As Irrum puts it: data is power, but only if the data is good.

And if you perform hip replacements, take the survey - it's under 10 minutes and open to surgeons at every stage. https://tinyurl.com/GAPSHIPS
