Summary

This study tested whether a personalized 3D-printed surgical guide (TOKA) helps surgeons correct knee alignment more accurately than standard surgery in people with knee osteoarthritis. 56 adults aged 18-65 with medial knee osteoarthritis took part. The goal was to see if the custom guide improves the precision of bone realignment, which could lead to better long-term outcomes.
