New sock could ease pain after knee surgery
NCT ID NCT04751942
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.
