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.

Outcome Measures
Primary Outcomes (1)
Evaluation of Bone Tunnel Footprint Localization Accuracy
The localization of bone tunnels is evaluated by comparing the deviation of each tunnel's position from its preoperative planned position at one week post-surgery (hereinafter referred to as "bone tunnel deviation value"). At one week post-surgery, each participant undergoes CT three-dimensional imaging of the knee joint on the surgical side, and the bone tunnel positions of the reconstructed ACL on the femur and tibia are measured. The measurement of the femoral tunnel uses the Bernard and Hertel method, measuring the ratio of the center point of the femoral tunnel relative to the Blumensaat line in terms of the horizontal length and height of the lateral femoral condyle. The measurement of the tibial tunnel uses the Stäubli and Rauschning method, measuring the ratio of the center point of the tibial tunnel in relation to the anterior-posterior and medial-lateral dimensions of the tibial plateau. Each research center has designated researchers review the images, and each tunnel cente

Study Arms (2)
Robotic Surgery after Preoperative Navigation
EXPERIMENTALAfter planning the preoperative bone tunnel using the navigation system from Naton Robotics, robotic surgery will be performed on the day of the operation.
Traditional Arthroscopic Surgery after Preoperative Navigation
ACTIVE COMPARATORAfter 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.
Interventions
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.

- Masking Details
- Throughout the clinical study, efforts should be made to keep participants blinded; however, since participants can learn which surgical instruments they used by obtaining a copy of their hospital records upon discharge, the blinding in this clinical study should be maintained as much as possible until the participants automatically unblind themselves.
