First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This pilot study tested a simple shoe wedge worn under the toes to help people straighten their knee after total knee replacement. Eight adults with a stiff knee (unable to fully straighten it) wore the wedge during walking for 4 weeks. The goal was to see if the wedge could reduce the knee stiffness without needing more surgery or anesthesia. This early study aims to guide future, larger research.
