Summary

This study tests whether nurse-led telehealth visits can detect complications and support recovery as well as in-person visits after total knee replacement. About 98 adults who had their first knee replacement will receive follow-up care either through a mobile app or at the clinic. The goal is to see if telehealth is a safe and convenient option that reduces travel and improves patient satisfaction.
