Case-control study on clinical effects of arthroscopic single-versus double-bundle ACLs reconstructions / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To compare the clinical results of arthroscopic single and double-bundle ACLs reconstructions.</p><p><b>METHODS</b>From January 2009 to May 2010,45 patients with anterior cruciate ligament tear were divided into two groups. In the first group,the anterior cruciate ligament were anatomical reconstructed with double-bundle semitendinous tendon, and in the second group the anterior cruciate ligaments were anatomical reconstrucated with single bundle semitendinous tendon. There were 22 patients (15 males and 7 females) in double-bundle group, with an average age of (27.04 +/- 3.68) years; 18 patients (13 males and 5 females) in single bundle group, with an average age of (28.16 +/- 4.76) years. Therapeutic effects between two groups were compared according to the IKDC, Lysholm scoring standards and Lachman test, knee pivot shift test, KT-1000.</p><p><b>RESULTS</b>Twenty-two patients in double-bundle group and 18 patients in single-bundle group were followed-up, and the mean duration was 12 months. The IKDC score of patients in single-bundle group improved from preoperative 41.40 +/- 6.30 to postoperatively 95.70 +/- 3.10, Lysholm score increased from preoperative 47.20 +/- 6.30 to postoperative 94.20 +/- 2.40. And the IKDC score of patients in double-bundle group improved from preoperative 40.90 +/- 6.10 to postoperative 96.10 +/-3.40, Lysholm score increased from preoperative 48.10 +/- 6.50 to postoperative 95.10 +/- 2.49. There was no statistically significant difference between the two groups. The Lachman test was positive in 2 patients (1 patient in double-bundle group and 1 patient in single-bundle group); and pivot shift test was positive in 2 patients (1 patient in double-bundle group and 1 patient in single-bundle group). KT-1000 of patients in double-bundle group was (1.5 +/- 1.2) mm, and (1.9 +/- 1.5) mm in single-bundle group, there were no statistically significant differences between the two groups.</p><p><b>CONCLUSION</b>Arthroscopic single-bundle reconstruction and double-bundle anterior cruciate ligament reconstruction have no significant differences in clinical effects.</p>
