Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study is tracking 600 people who receive a special hip implant called the MPACT dual mobility cup during total hip replacement. The main goal is to see how many implants are still working well after 10 years. Researchers will also measure how well the hip functions using a standard score. The study is currently recruiting participants aged 18 to 80 who need a first-time hip replacement.

What this could mean

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

Active substance
MPACT dual mobility hemispheric cup (hip implant device)
What this could lead to
If successful, this could confirm that the MPACT cup lasts at least 10 years in most patients, supporting its use in hip replacement surgery.
What could go wrong
This is an observational study without a comparison group, so results may not prove the cup is better than other implants. Long-term follow-up may also have dropouts.
