Could a single antibiotic dose before hip replacement be just as effective as multiple doses?

NCT ID NCT05530551

First seen Jul 08, 2026 · Last updated Jul 09, 2026 · Updated 1 time

Summary

This trial investigates whether a single dose of antibiotics before hip replacement surgery prevents joint infections as effectively as multiple doses. The study involves about 20,000 adults with osteoarthritis undergoing hip replacement at hospitals across Denmark. Researchers will compare infection rates between the two antibiotic strategies to see if one dose is enough.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
antibiotics (cloxacillin, dicloxacillin, cefuroxime, or clindamycin)
What this could lead to
If one dose works as well as multiple doses, it could simplify infection prevention for hip replacement patients and reduce antibiotic use.
What could go wrong
This is a large trial, but results may not apply to other surgeries or patient groups. There is always a risk of infection regardless of antibiotic strategy.
