The role of isolated posterior cruciate ligament reconstruction in knees with combined posterior cruciate ligament and posterolateral complex injury.

摘要: Purpose This is a meta-analysis comparing biomechanical outcomes to determine whether an isolated posterior cruciate ligament (PCL) reconstruction can restore normal knee kinematics in combined PCL/posterolateral complex (PLC) injury and double-bundle (DB) PCL superior controlling rotational laxity compared with single-bundle (SB) PCL/PLC-deficient knee. Methods A number of electronic databases were searched for relevant articles published through August 2016 that patients who underwent PCL/PLC deficiencies. Data searched, extracted, analysed, assessed quality according Cochrane Collaboration guidelines, evaluated using various outcome values. The results are presented as relative ratios binary standard mean differences continuous 95% confidence intervals. Results Five studies included this meta-analysis. There significant laxities such tibial translation (PTT), external rotation, varus PTT coupled rotation the group native group. Furthermore, there no PTT, or between SB DB groups. Conclusion Isolated reconstruction, DB, could not In cases, residual after be controlled successfully PLC reconstruction. Therefore, simultaneous recommended injury.
