Brief Summary

The ACL surgery robot features a preoperative navigation system that enhances the precision of bone tunnel placement. As the first dual-bundle reconstruction surgical robot developed in China, it integrates advanced technology to ensure accurate anatomical alignment. This multi-center study aims to evaluate the robot's effectiveness in improving surgical outcomes and reducing complications, demonstrating the potential of domestic innovations in orthopedic surgery. With its high accuracy in locating bone tunnel footprints, this robot represents a significant advancement in ACL reconstruction techniques.

The trial is designed as a randomized controlled trial (RCT) led by a prospective randomized cohort. The study is initiated by Tsinghua University's long-term professor, Yu Jiakuo, and the product has received China's Class III clinical registration certificate.

Study Groups

Robotic Surgery after Preoperative Navigation

After planning the preoperative bone tunnel using the navigation system from Naton Robotics, robotic surgery will be performed on the day of the operation.

Group Type: EXPERIMENTAL

ACL footprint localization after preoperative navigation executed by robotic arm

Intervention Type: PROCEDURE

Anterior cruciate ligament (ACL) reconstruction is performed using the preoperative navigation of Naton Robotics, followed by random assignment to either robotic surgery or traditional manual surgery. The difference between the two lies in whether the localization of the ACL footprint is performed by a human or by the robotic arm. The surgical technique is standardized as double-bundle reconstruction.

Traditional Arthroscopic Surgery after Preoperative Navigation

After planning the preoperative bone tunnel using the navigation system from Naton Robotics, a senior physician will perform traditional arthroscopic surgery on the day of the operation.

Group Type: ACTIVE_COMPARATOR

ACL footprint localization after preoperative navigation executed by rmanual execution

Intervention Type: PROCEDURE

Anterior cruciate ligament (ACL) reconstruction is performed using the preoperative navigation of Naton Robotics, followed by random assignment to either robotic surgery or traditional manual surgery. The difference between the two lies in whether the localization of the ACL footprint is performed by a human or by the robotic arm. The surgical technique is standardized as double-bundle reconstruction.
