Pdf Summary

A meta-analysis compared double-bundle (DB) and single-bundle (SB) posterior cruciate ligament (PCL) reconstruction techniques, finding that DB reconstruction had superior outcomes in terms of reduced laxity and higher clinical success rates. Most studies utilized interference screws for fixation and postoperative braces for rehabilitation. Patient demographics were similar between the two groups, with no substantial differences. Overall, the study emphasized that re-creating native anatomy through DB reconstruction is crucial for optimal stability and clinical results. The document highlights the improved biomechanical and clinical outcomes of DB PCL reconstruction compared to SB reconstruction, suggesting that DB technique leads to reduced laxity and improved objective and subjective IKDC outcomes, as well as enhanced in vivo and in vitro stability. The safety profile of DB reconstruction was deemed comparable to SB reconstruction. Although the study acknowledged some limitations, it recommends further randomized investigations to confirm the advantages of DB reconstruction and assess its true clinical value in PCL surgeries.
