Beneficial Effect of Curved Dilator System for Femoral Tunnel Creation in Preventing Femoral Tunnel Widening after Anterior Cruciate Ligament Reconstruction
Round 1
Reviewer 1 Report
The authors compare the results for ACL reconstruction using two techniques for femoral tunnel creation: reaming through antero-medial approach versus curved dilator system. Actually, they are comparing the femoral tunnel widening at 2 years from surgery. Since widening of the femoral tunnel is a well-known and potentially dangerous complication of ACL reconstruction, this comparison might be of practical use for the attending orthopedic surgeons Even though CDS system use is not the only technical option to avoid the tunnel widening, their results demonstrate it is effective. The study is well conducted and the results are very nicely presented.
There are some minor issues
Fig. 1 – Are these pictures from the same patient? When were they acquired? Immediately after surgery or 2 years later? It would be useful to mention these details.
References are not numbered in order of appearance in the text and are numbered twice in the reference list

Reviewer 2 Report
Exclusion criteria should be added. Inclusion criteria should be expanded and more detailed information should be given.
In the material method section, a descriptive explanation of Lysholm score and subjective International Knee Documentation Committee (IKDC) scores can be given with a few sentences.
Information about inter-rater and intrarater reliability is not provided in the measurements made. This can be measured using statistical methods such as Cohen's kappa coefficient, intraclass correlation coefficient (ICC), or Fleiss' kappa.
