Influencing factors of high-grade pivot shift in ACL injuries based on 3T MRI

Motivation: Anterior cruciate ligament (ACL) reconstruction surgery often fails to fully restore the natural knee joint function. Goal(s): Investigate if factors like anterolateral ligament abnormalities (ALL), lateral and medial posterior tibial slope (LPTS and MPTS), lateral and medial collateral ligament injury (LCL and MCL), and intraoperative lateral and medial meniscus injuries (LM and MM) are linked to high-grade pivot shift in ACL injuries. Approach: Case-controlled subjects were imaged using 3T MRI to analyze the effects of these factors. Results: LPTS, ALL, and LM injuries in ACL cases may be high-risk factors associated with high-grade pivot shift. Impact: In future treatment of ACL injuries, it may be necessary to consider the impact of these risk factors and improve surgical strategies, to improve outcomes, facilitate recovery, and minimize the occurrence of long-term complications.
