Kim JH, Oh E, Yoon YC, et al. - In this study, the clinical, second-look arthroscopic, magnetic resonance imaging (MRI), and dynamic contrast enhanced-MRI (DCE-MRI) findings were compared between remnant-tensioning single-bundle (RT-SB) and double-bundle (DB) anterior cruciate ligament reconstruction (ACLR). Researchers randomized 67 individuals with acute or subacute anterior cruciate ligament (ACL) injury to undergo RT-SB or DB ACLR. They assessed 26 patients in the RT-SB group and 28 patients in the DB group applying stability tests (Lachman test, pivot-shift test, and KT-2000 arthrometer) and multiple clinical scores. The RT-SB ACLR exhibited comparable outcome to the DB ACLR in terms of knee stability, clinical scores, MRI findings, and second-look arthroscopic findings for acute or subacute ACL injury. Furthermore, the graft of RT-SB ACLR exhibited better graft vascularity than those of DB ACLR applying DCE-MRI on 1-year postoperatively.
