Summary

This trial explores whether using a custom 3D-printed knee extender, along with a home exercise program, helps people regain knee motion after ACL surgery. Participants who had an ACL tear will use the device at home and report their progress. The study measures how quickly they achieve full knee extension and how much swelling they have. The goal is to see if this simple tool can improve recovery outcomes.
