The median age of the patients at the time of the index operation was 26 years (range, 14 to 53 years). The patients underwent surgery at a median of 12 months (range, 0.5 to 360 months) after their injury. Independent physiotherapists performed the follow\u2010up examinations at a median of 32 months (range, 21 to 117 months) postoperatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Of the 948 patients, 550 (58%) underwent meniscal surgery before, during, or after the ACL reconstruction. The median Tegner activity level was 8 (range, 2\u201310) before injury, 3 (range, 0\u20139) preoperatively, and 6 (range, 1\u201310) at follow\u2010up (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .0001 preoperative\n                      <jats:italic>v<\/jats:italic>\n                      follow\u2010up). At follow\u2010up, the median Lysholm score was 90 points (range, 14\u2013100), the median KT\u20101000 anterior side\u2010to\u2010side laxity difference was 1.5 mm (range, \u22126 to 13 mm), and the median 1\u2010leg hop test quotient was 95% (0% to 167%) compared with the contralateral normal side. At follow\u2010up, 69.3% of the patients were classified as normal or nearly normal according to the International Knee Documentation Committee evaluation system. However, 36% of the patients were unable to or had severe problems performing the knee\u2010walking test. Inferior results correlated with increased time period between the index injury and reconstruction and concomitant joint damage found at the index operation.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Overall, the results were good after ACL reconstruction using patellar tendon autograft and interference screw fixation.
