“…Contradictory to the previous findings, TI technique placed femoral aperture at a significantly shallower position than the TT technique as measured by Harner method [ 77 ] on radiography in 2 studies (92 participants) [ 28 , 46 ] (Additional file 6 ). A consistent finding was demonstrated in one study (30 patients) [ 20 ], where the placed femoral aperture screw head of TI technique was at a significantly shallower position than that of the TT technique as measured by the quadrant method on radiography. Also, in one study (12 specimens) [ 65 ], TI technique placed femoral aperture anterior margin at a significantly shallower position than the TT technique as measured by Aglietti method [ 77 ] directly on specimen.…”

Background Femoral tunnel can be drilled through tibial tunnel (TT), or independent of it (TI) by out-in (OI) technique or by anteromedial (AM) technique. No consensus has been reached on which technique achieves more proper femoral aperture position because there have been evolving concepts in the ideal place for femoral aperture placement. This meta-analysis was performed to analyze the current literature comparing femoral aperture placement by TI versus TT techniques in ACL reconstruction. Methods We performed a comprehensive systematic review and meta-analysis of English-language literature in PubMed, Cochrane, and Web of Science databases for articles comparing femoral aperture placement by TI versus TT techniques with aperture position assessed by direct measurement or by postoperative imaging, PXR and/or CT and/or MRI. Results We included 55 articles with study population of 2401 knees of whom 1252 underwent TI and 1149 underwent TT techniques. The relevant baseline characteristics, whenever compared, were comparable between both groups. There was nonsignificant difference between TI and TT techniques in the distance from aperture center to footprint center and both techniques were unable to accurately recreate the anatomic footprint position. TI technique significantly placed aperture at more posterior position than TT technique. TI technique significantly lowered position of placed aperture perpendicular to Blumensaat’s line (BL) than TT technique, and modifications to TT technique had significant effect on this intervention effect. Regarding sagittal plane aperture placement along both AP anatomical axis and BL, there was nonsignificant difference between both techniques. Conclusion Modifications to TT technique could overcome limitations in aperture placement perpendicular to BL. The more anterior placement of femoral aperture by TT technique might be considered, to some extent, a proper position according to recent concept of functional anatomical ACL reconstruction.

“…77 Postoperative cross-sectional imaging was also frequently used to compare tunnel characteristics after ACL reconstruction. 11,18,31,60 Three magnetic resonance imaging (MRI) studies demonstrated that femoral tunnels drilled independently were more oblique in the coronal and sagittal planes as compared with TT femoral tunnels. 11,18,31 There was also evidence that the aperture of the femoral tunnel was closer to the center of the anatomic footprint when independent drilling was used.…”

One group found that reconstruction through an AMP restored the normal tibial translation profile but led to more tibial rotation than in the normal knee.…”
