Aim of this study is to evaluate if the conservative treatment of an injured ACL could influence at more than ten years from injury, the status of the affected knee and the activity level of the individual. 17 patients were evaluated, 15 males (88.2%) and 2 females (11.8%), at a mean follow-up of 12.6 years (range, 10 to 26 years). Mean patient’s age was 37.1 years (range, 30 to 48 years). The ACL injury was diagnosed arthroscopically and a medial meniscectomy was performed in eleven patients (64.7%). Patient’s clinical evaluation was based on IKDC, Lysholm and Tegner scales. Stability tests were performed with a KT-2000 arthrometer. Bilateral standing AP and LL x-rays were obtained to evaluate the presence of arthritis, according to Sasaki and Fairbank classifications. Data were analyzed by means of independent and paired samples t-tests . The good clinical conditions observed (mean IKDC score 2.3 points; range, 1 to 3 points - mean Lysholm score 95.6 points; range, 78 to 100 points - mean Tegner score 6.3 points; range, 3 to 7 points) and the subjective satisfaction of the patients are in contrast with the poor x-rays conditions. All injured knees reported the radiographic evidence of arthritis (mean Sasaki value 2.3°; range 1° to 3° - mean Fairbank value 2.1°, range 1° to 3°) opposed to the significantly less arthritic counter-lateral knees (mean difference for both Sasaki and Fairbank scales 0.8°, p=0.049 and p=0.47 respectively), in asymptomatic patients whose quality of life was not compromised by the ACL injury.

Abstract
Aim of this study is to evaluate if the conservative treatment of an injured ACL could influence at more than ten years from injury, the status of the affected knee and the activity level of the individual. 17 patients were evaluated, 15 males (88.2%) and 2 females (11.8%), at a mean follow-up of 12.6 years (range, 10 to 26 years). Mean patient’s age was 37.1 years (range, 30 to 48 years). The ACL injury was diagnosed arthroscopically and a medial meniscectomy was performed in eleven patients (64.7%). Patient’s clinical evaluation was based on IKDC, Lysholm and Tegner scales. Stability tests were performed with a KT-2000 arthrometer. Bilateral standing AP and LL x-rays were obtained to evaluate the presence of arthritis, according to Sasaki and Fairbank classifications. Data were analyzed by means of independent and paired samples t-tests . The good clinical conditions observed (mean IKDC score 2.3 points; range, 1 to 3 points - mean Lysholm score 95.6 points; range, 78 to 100 points - mean Tegner score 6.3 points; range, 3 to 7 points) and the subjective satisfaction of the patients are in contrast with the poor x-rays conditions. All injured knees reported the radiographic evidence of arthritis (mean Sasaki value 2.3°; range 1° to 3° - mean Fairbank value 2.1°, range 1° to 3°) opposed to the significantly less arthritic counter-lateral knees (mean difference for both Sasaki and Fairbank scales 0.8°, p=0.049 and p=0.47 respectively), in asymptomatic patients whose quality of life was not compromised by the ACL injury.
