Methods: In a prospective trial, 62 patients were randomized into two groups based on method of fixation. Transtibial drilling technique was used in the cross-pin and outside-in femoral drilling in the interference screw fixation group. Clinical and radiographical outcomes were assessed 2 and 5years postoperatively. Results: The study showed no clinically significant difference with respect to method of graft fixation. Mean anteroposterior side-to-side instrumented laxity difference was 2.4mm in the cross-pin group and 2.5mm in the screw group (n.s.). Median Tegner and mean Lysholm scores at 5years were 6 (range 3-9) and 92.2 (range 69-100) in the screw group and 7 (3-10) and 93.3 (82-100), respectively, in the cross-pin group. Radiographical osteoarthritis increased in both groups from 2 to 5years after reconstruction (p<0.05), especially in the medial and patellofemoral joint spaces. Widening of the drill tunnels continued from 2 to 5years without clinical significance. Conclusions and clinical relevance: The method of graft fixation did not yield a difference in clinical or radiographical outcome at 5years. Results were excellent in both groups.
