Bone-Patellar tendon–bone autograft maturation is Efficaciou
The primary purpose of this study was to evaluate the second-look arthroscopic findings 1 year postoperatively and (MRI) findings 2 years after anterior cruciate ligament reconstruction (ACLR) using bone-patellar tendon–bone autograft (BTB) or hamstring tendon autograft (HT).

75 patients with primary ACL injuries were divided into either the BTB group (n=30) or HT group (n=45). When using HT, an anatomical double-bundle ACLR was performed. BTB was indicated for athletes with sufficient motivation to return to sporting activity. Graft maturation on second-look arthroscopy was scored in terms of synovial coverage and revascularization.

Results:
--Arthroscopic findings showed that the graft maturation score in the BTB group was significantly greater than that in the anteromedial bundle and posterolateral bundle in the HT group.

--The mean MRI-SNQs were as follows: BTB, 2.3±0.5; AMB, 2.9±0.9; and PLB, 4.1±1.1. There were significant differences between BTB, AMB, and PLB.

--Second-look arthroscopic maturation score and MRI-SNQ value significantly correlated for BTB, AMB, and PLB.

--No significant differences were detected in clinical scores. There was a significant difference in the knee laxity evaluation.

Based on morphological and MRI analyses during anatomical ACLR, BTB maturation is superior than that of double-bundle HT, despite no significant changes in clinical scores.
