Summary

This study tested whether a special non-compressive bioactive garment helps people recover better than standard TED stockings after total knee replacement. Twenty-three patients wore either the new garment or the standard hose, and researchers measured pain, swelling, range of motion, and painkiller use. The goal is to find a more comfortable way to reduce pain and swelling right 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
Non-compressive bioactive garment (device)
What this could lead to
If this garment works better than standard stockings, it could give people a more comfortable way to recover after knee replacement surgery with less pain and swelling.
What could go wrong
This is a very small, early study with only 23 participants, so results may not apply to everyone. The garment might not prove better than the current standard care.
