KRONOS vs. Breg T-Scope Braces for ACL Reconstruction

This study is comparing two different knee braces, the KRONOS brace and the Breg T-Scope brace, after anterior cruciate ligament (ACL) reconstruction surgery. The KRONOS brace is a new type of brace that can help take pressure off your knee joint. Researchers want to see if the KRONOS brace helps reduce pain and improve recovery better than the standard Breg T-Scope brace. They will measure how well your knee can straighten (extension deficit) one year after surgery. You may be able to join if you are over 18, speak English, are having your first ACL reconstruction surgery, and don't have other knee ligament problems. The current status of this study is unclear.

Study design
This is an interventional study with 40 participants, comparing two different braces. Participants will be randomly assigned to receive either the KRONOS brace or the Breg T-Scope brace.
What's involved
Participants will be fitted with their assigned brace at their initial clinic visit after joining the study, or in the operating room.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for one year after their surgery to measure their knee's ability to straighten.
