In both groups, grafts were fixed at 30\u00b0 of flexion with a total tension of 80\u00a0N. The following evaluation methods were used: clinical examination, KT\u20101000 arthrometer (MEDmetric, San Diego, CA) measurement, muscle strength, Tegner activity score, Lysholm score, subjective rating scale regarding patient satisfaction and sports performance level, graft retear, contralateral ACL tear, and additional meniscus surgery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Fifty\u2010three patients (25 in SB group and 28 in DB group) who were followed up for a minimum of 3\u00a0years (mean, 69\u00a0months; range, 36 to 140\u00a0months) were evaluated.
