Two independent observers analyzed preoperative and immediate postoperative computed tomography scans of 20 open (group O) and 20 arthroscopic (group A) procedures. Defect and ICBG characteristics of the J\u2010shaped graft in the en\u2010face view and axial plane were manually assessed by multiplanar reconstructed computed tomography scans. Variances in terms of graft positioning were analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      No significant variances in arthroscopic graft positioning were observed. The graft position in the en\u2010face view was comparable in both groups, with the superior extent of the arthroscopic graft (40\u00b0 \u00b1 9\u00b0 [inferior extent, 139\u00b0 \u00b1 16\u00b0]) lying significantly higher than the superior extent in group O (50\u00b0 \u00b1 13\u00b0,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .005 [inferior extent, 147\u00b0 \u00b1 21\u00b0;\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .178]).

The arthroscopic graft in the axial plane showed a significantly steeper impaction angle (34.8\u00b0 \u00b1 7.8\u00b0 vs 26.9\u00b0 \u00b1 9.9\u00b0,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .010), with a significantly increased medial offset compared with group O (6.6 \u00b1 1.7\u00a0mm vs 5.4 \u00b1 1.3\u00a0mm,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .024). The mediolateral step formation, however, was not significantly different (2.9 \u00b1 1.1\u00a0mm in group A vs 3.2 \u00b1 0.8\u00a0mm in group O,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .289).
