Summary

This study looks at whether using a 3D patient-specific alignment during knee replacement surgery leads to better walking, less pain, and stronger muscles. Researchers will measure movement, pain, and strength in 45 adults who had surgery two years ago. The goal is to understand if custom alignment helps people recover more naturally.
