Purposes: The purpose of this study was to report surgical technique of double bundle anterior cruciate
igament (ACL) reconstruction and to compare the short-term clinical results between arthroscopic single-bundle and double-bundle ACL reconstruction.
Materials and Methods: From May 2005 to May 2006, ninety-eight patients were underwent ACL reconstruction. We designed prospective study with sixty-one patients who were revealed isolated ACL injury. We serially checked clinical and radiologic data preoperatively and postoperatively. We compared single-bundle with double-bundle ACL reconstruction patients with preoperative datas and postoperatively 1-year data. There were 30 single bundle reconstruction and 31 double bundle reconstruction. Stability was assessed objectively by anterior stress radiographs
with the Telos? device and the maximal manual test with the KT-2000 arthrometer. The clinical results were assessed
by IKDC (International Knee Documentation Committee) and OAK (Orthopadische Arbeitsgruppe Knie) scores. Also, we evaluated postoperative thigh circumference and range of motion. All of operations were done by only one surgeon.
Results: At single-bundle reconstruction group, preoperative AP instability which was checked by Telos?
device and the maximal manual test with the KT-2000 arthrometer was 7.9±3.3 and 7.4±2.0, respectively. At double-bundle reconstruction group, it was 8.3±3.5 and 7.9±3.2, respectively. Residual AP laxity checked at 1 year after
operation was 1.9±1.2 and 2.2±1.6 in single-bundle reconstruction group, and 1.1±0.9 and 1.0±1.0 in double-bundle reconstruction group. So, double-bundle reconstruction had better results in both anterior stress radiographs with the Telos? device
and the maximal manual test with the KT-2000 arthrometer, and there were significant differences in statistics. But,
clinical results such as IKDC (International Knee Documentation Committee) scores, OAK (Orthopadische Arbeitsgruppe Knie) scores, thigh circumference and range of motion had no significant difference between two groups.
Conclusions: On the basis of stability, the side-to-side anterior laxity of double-bundle ACL reconstruction
was significantly better than that of single-bundle reconstruction, although there were no significant differences in the
other clinical measures among them.
