CT Based Analysis of Arthroscopic Femoral Tunnel Placement in Single Bundle Primary ACL Reconstruction Using Medial Portal Technique
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 3
Abstract
Background: Achieving anatomical graft placement remains one of the major challenges in ACL reconstruction. In this study we analyzed the anatomic femoral tunnel placement of single bundle endoscopic ACL reconstruction by the medial portal technique using 3D CT reconstruction. Materials & Methods: This cross - sectional observational study was performed on 35 consecutive cases of ACL injury presenting over a period of one year. Post-operatively analysis of femoral tunnel placement was done using Mochizuki’s method. The data recorded was subjected to standard statistical analysis. Results: Our study had 29 males and 6 females between 20-50 years of age. In accord with the variance from anatomical position of femoral tunnel by Mochizuki’s method expressed as percentage {38.7% ± 2.7% as reported by Mochizuki et al}, 18(52%) patients were within the percentage group of 35-39.9. Between the percentage group of 40-44.9 there were 10(29%) patients while 4(11%) were between the percentage group of 30-34.9 and only 3(8%) patients were between 45-50. Conclusions: The use of medial portal technique allows anatomical ACL tunnel placement. This technique is not limited by the choice of graft or fixation and offers the advantage of true parallel screw placement through the same portal as that used for tunnel drilling in the case of interference fixation. The anteromedial portal technique helps in accurate position of the native footprint in ACL reconstruction.
