Anatomic Versus Traditional Over-the-top Single-bundle In Arthroscopic Reconstruction Of Anterior Cruciate Ligament

Objective: To compare the recent clinical results of the arthroscopic single-bundle ACLreconstruction with traditional over-the-top and anatomic femoral insertions.Method: The curative results and follow-up data were retrospective analyzed in63caseswith ACL injure which were treated with ACL reconstruction in Tongji hospital ofHuazhong University Of Science And Technology from October2010to October2012.Allcases were performed single-bundle reconstruction with autogeneic hamstring tendons anddivided into2groups according to surgical opinions as group of traditional over-the-topACL reconstruction, and group of anatomical ACL reconstruction.To compare and analyzethe functions of knee after3to6months of operation respectively.The knee functions wereevaluated by active joint flexion degree,Pivot shift test,Lachman test,IKDC and Lycholmscores.Result: The active joint flexion degree:3cases presented5~10°extension limitation in CSBwith no flexion limitation;no flexion limitation and extension limitation in ASBcases.Lachman test:all cases presented negative Lachman test after3to6months ofoperation in ASB;in CSB6cases presented Lachman test positive after3to6months ofoperation.Negative pivot shift was66.7%in ASB vs41.7%in CSB.Lysholm and IKDCscores increased significantly after operation, however, there’s no significance differentbetween two groups on these two scores.Conclusion: ASB reconstruction resulted in better anteroposterior and rotational stabilitythan CSB reconstruction.However, these differences are small and may not be clinicallyrelevant. So further follow-up clinical study are needed.
