What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

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 trial compares two types of knee replacement implants in people aged 75 and older: a standard metal-backed component and a cheaper all-polyethylene (plastic) one. The goal is to see if the all-polyethylene implant performs as well in terms of pain relief, movement, and how long it lasts. Participants are randomly assigned to receive one of the two implants and are followed for five years after surgery.

What this could mean

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

Active substance
knee replacement implant (all-polyethylene tibial component vs metal-backed tibial component)
What this could lead to
If the all-polyethylene component performs as well as the metal-backed one, it could offer a more cost-effective option for knee replacement in older adults.
What could go wrong
This is a relatively small trial, and the all-polyethylene component may not be as durable or effective as the metal-backed version over the long term.
