Summary

This study looked at how sleep health impacts recovery quality in 174 adults after hip or knee replacement surgery. Participants wore activity monitors and kept sleep diaries to track their sleep patterns. The goal was to see if poor sleep leads to worse recovery, helping doctors improve patient care before and after surgery.
