Abstract
INTRODUCTION: Rupture of the anterior cruciate ligament (ACL) has been surgically reconstructed mainly arthroscopically for many years. The long-propagated single bundle replacement was followed by recommendations for the anatomical double-bundle reconstruction. The aim of this study is the evaluation of clinical follow-up results in terms of function and stability after performing an ACL reconstruction with both the single bundle (SB) and the double bundle (DB) technique. METHODOLOGY: Eighty patients receiving ACL reconstruction were included (41 SB / 39 DB). The follow-up period was 17.4 months. To assess knee joint stability, anteroposterior translation and rotation translation were determined. In addition, arthrometric measurement and the implementation of standardized scores were performed. Data were statistically evaluated using the Pearson χ2 test and Fisher's exact test (p = 0.05). RESULTS: While the Lachman test in the SB group showed a significant (p = 0.032) greater stability of the knee joints, a higher stability of the knee joints in the DB group was documented by the anterior drawer test and the stability measurement with the rolimeter. In the DB group a significantly higher number of patients with local sensitivity deficits (p = 0.045) and paresthesia as well as a significantly higher active and passive flexion deficit were noted compared to the SB group (p = 0.09 / p = 0.038, respectively). CONCLUSION: Based on the results of this study it is currently not possible to give any recommendations regarding any operating procedure after a follow-up period of at least 12 months. However, there is evidence of a higher complication rate in the DB group. Clinically, these results should be considered in the evaluation of the indications.
