Individuals with prior injury or surgery of either knee, greater than a grade 1 concomitant knee ligament injury, or ACL insertion sites less than 14\u00a0mm or greater than 18\u00a0mm were excluded. Subjects were randomized to undergo SB or DB ACLR with a 10\u00a0mm\u2010wide quadriceps tendon autograft harvested with a patellar bone block and were followed for 24\u00a0months. The primary outcome measures included the IKDC\u2010SKF and KT\u20101000 (side to side difference) and pivot shift tests. Other secondary outcomes included measures of sports activity and participation, range of motion (ROM) and re\u2010injury.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Enrollment in the study was suspended due to patellar fractures related to harvest of the patellar bone plug.

At 24\u2010month follow\u2010up there were no between\u2010group differences detected for the primary outcomes.
