Hip stem movement measured in new study
NCT ID NCT04879732
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study measured how much the ACTIS hip stem moves (subsides) over two years after hip replacement surgery in 64 people with hip osteoarthritis. Researchers used a special X-ray technique called RSA to compare the implant's movement to published data for similar hip stems. The goal was to see if the ACTIS stem stays in place as well as other designs.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
ACTIS hip stem (a medical device used in hip replacement surgery)
What this could lead to
If successful, this study could confirm that the ACTIS hip stem stays in place well, which may lead to better long-term outcomes for hip replacement patients.
What could go wrong
This is a small, completed study focused on measuring implant movement, not on curing disease. Results may not apply to all patients or guarantee better outcomes.
