NCT05076539

Brief Summary

This study aims to evaluate the patients' mobility and quality of life prior to their total knee replacement surgery and their progress pre-operatively and 6 months post-operatively using the smart activity tracker. We hypothesize that mobility limitation presents a strong correlation with reduced quality of life.
