The Clinical Efficacy of Anterolateral Complex Augmentation in Patients With ACL Rupture Combined With Excessive Internal Tibial Rotation Subluxation: A Bidirectional Cohort Study
This project aims to establish a high-quality, large-scale, single-center bidirectional cohort study to evaluate the postoperative clinical efficacy of ACLR combined with ALC augmentation in a specific high-risk population-patients with ACL rupture exhibiting excessive internal tibial rotation subluxation (EIRTS) on preoperative MRI. The study population will consist of patients with primary ACL rupture, and high-risk individuals will be identified based on the presence of EIRTS on preoperative knee MRI. The exposure group will undergo ACLR combined with ALC augmentation, while the control group will receive standard ACLR. Observational indicators will include all baseline patient characteristics and postoperative clinical outcomes.

Inclusion Criteria:
* Age ≥ 18 years; Primary unilateral ACL rupture; Preoperative knee MRI completed at our institution; Diagnosis of excessive internal tibial rotation subluxation (EIRTS) based on preoperative MRI measurements (i.e., internal rotation tibial subluxation \[IRTS\] \> 5.8 mm); Patient has been informed of the study details and has provided written informed consent to participate in this cohort study.
Exclusion Criteria:
* Concomitant injury to the medial collateral ligament (MCL), lateral collateral ligament (LCL), or posterior cruciate ligament (PCL); History of contralateral knee injury; History of patellar dislocation; History of prior knee surgery.
Primary outcome measure(s)
Graft Failure Rate — At 2 and 5 years postoperatively Graft failure was identified based on physical examination findings and postoperative MRI scans at the designated follow-up time points.
Return to Pivoting Sports: Rate and Time — At 2 and 5 years postoperatively The rate and timing of return to pivoting sports were recorded at each follow-up time point.
