ACL Reconstruction Recovery Study with Ermi Knee Extensionater

This study is looking at ways to help people recover full knee movement after ACL (anterior cruciate ligament) surgery. It compares standard physical therapy to physical therapy combined with a device called the Ermi Knee Extensionater, which helps with stretching at home. You might be able to join if you are 14-65 years old and are having your first ACL reconstruction using a specific type of graft. The main goal is to see if adding the Ermi Knee Extensionater helps improve your knee's range of motion (how far it can bend and straighten) at 2 weeks, 6 weeks, and 3 months after surgery. The study is currently unclear on its recruitment status and plans to enroll 58 participants.

Study design
This interventional study aims to enroll 58 participants. It compares two groups: one receiving standard physical therapy and another receiving standard physical therapy plus a home device.
What's involved
Participants will receive standard physical therapy. Those in the device group will also use the Ermi Knee Extensionater daily at home, with stretching protocols provided preoperatively. Knee range of motion will be measured at baseline, 2 weeks, 6 weeks, and 3 months.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for at least 3 months, with measurements taken at 2 weeks, 6 weeks, and 3 months after surgery.
