The secondary purpose was to identify predictive factors for good outcome and occurrence of osteoarthritis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Sixty\u2010three patients (<jats:italic>m<\/jats:italic>:<jats:italic>f<\/jats:italic> = 54:9; mean age at surgery, 27 \u00b1 7 years) treated by ACL reconstruction were evaluated with a mean follow\u2010up of 16 \u00b1 1 years using IKDC2000, the SF36, Lysholm and Tegner score, Knee Society score, visual analogue scale for pain and satisfaction and KOOS. The femoral tunnel position was evaluated according to Sommer. It was also assessed in percentage of the Blumensaat line and the tibial tunnel position in percentage of the total anterior\u2013posterior plateau length. The extent of osteoarthritis was graded according to the Kellgren\u2013Lawrence score.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The total IKDC2000 was normal in 20 (32 %), nearly normal in 29 (46 %), abnormal in 12 (19 %) and severely abnormal in 3 (5 %) of patients. The mean total SF\u201036 was 89 \u00b1 13, the Lysholm score 95 \u00b1 12, the Knee Society score 191 \u00b1 16 and the total KOOS 84 \u00b1 19. The Tegner score decreased from pre\u2010injury 7(4\u201310) to 6 (2\u201310) at follow\u2010up. The Kellgren\u2013Lawrence score was normal in 17 (27 %), suspected osteoarthritis in 25 (40 %), minimal osteoarthritis in 5 (8 %), moderate osteoarthritis in 9 (14 %) and severe osteoarthritis in 3 patients (5 %). The femoral tunnel was in zone A in 43 patients (68 %), in zone B in 16 (25 %) and in zone C in 4 patients (7 %). The femoral tunnel position in percentage of the Blumensaat line was 49 \u00b1 3 (range, 44\u201357), and the tibial tunnel position in percentage of the total anterior\u2013posterior plateau length was 32 \u00b1 6 (range, 21\u201346).
