Abstract Background All-inside anterior cruciate ligament reconstruction (ACLR) is a novel technique that has gained attention due to its minimally invasive and graft-saving properties. However, studies comparing MRI-based graft maturity between all-inside standard ACLR are lacking. Purpose This study focused on the functional, knee laxity, characteristics of single-bundle ACLR. Study Design Randomized controlled trial (RCT). Methods Fifty-four patients were randomly assigned an group ( n = 27) or 27). Using same rehabilitation strategy. The Tegner, International Knee Documentation Committee, Lysholm scores recorded at postoperative months 3, 6, 12 assess functional recovery. MRI was conducted measure signal/noise quotient (SNQ) intra-articular maturity. A higher SNQ indicates lower laxity assessed using GNRB arthrometer month 12. Results significantly than 6 p < 0.05). There no statistical difference in two groups 3 > Both exhibited highest middle region graft, followed by proximal region, distal region. Functional improved for both had 0.05) correlation Conclusions show good outcomes; however, relatively group. Moreover, techniques poor best Graft with inferior early stages. function Trial registration Clinical numbers: ChiCTR1800018543 . Date registration: 09/23/2018.
