title: A comparison of arthroscopic single- and double-bundle posterior cruciate ligament reconstruction: review of 20 cases.
abstract: In the study reported here, we evaluated postoperative outcomes of arthroscopic posterior cruciate ligament (PCL) reconstruction using hamstring tendons and compared single- and double-bundle reconstructions. Twenty patients with isolated PCL tears and multiligamentous knee injuries were enrolled. Single-bundle (group S) and double-bundle (group D) reconstructions were applied to 10 patients each. Posterior tibial translation was measured using stress radiography before surgery and 2 years after surgery. Second-look arthroscopy was also performed in each knee. Two years after surgery, mean side-to-side differences in posterior tibial translation of groups S and D were 3.4 mm (SD, 3.0 mm) and 4.9 mm (SD, 2.8 mm), respectively. There was no significant difference in short-term stability between the 2 groups. Second-look arthroscopy showed 3 ruptures of the posteromedial bundle in the double-bundle technique.
