Timing of Surgery & Rehabilitation After Multiligamentous Knee Reconstruction.

Purpose of review: To provide an overview of the current evidence of the timing of surgery and rehabilitation after multiligamentous knee injuries (MLKIs) and offer insights into the ongoing multi-center randomized controlled study, the 'STaR trial'.

Recent findings: Due to the complexity of the MKLIs, they are usually treated surgically with the goal of either repairing or reconstructing the injured ligaments. Although the current literature on MLKIs is relatively extensive, the consensus on the timing of surgery or rehabilitation following surgery for MLKIs is still lacking. While current literature mostly suggests early treatment, there is also evidence preferring delayed treatment. Furthermore, evidence on the timing of postoperative rehabilitation is limited. Thus, the current multi-center randomized controlled study, the 'STaR trial', is expected to respond to these questions by adding new high-level evidence. The MLKIs are often associated with knee dislocation and constitute a highly complex entity, including concomitant injuries, such as neurovascular, meniscal, and cartilaginous injuries. The treatment of MLKIs usually aims to either repair or reconstruct the injured ligaments, however, there is no general consensus on the timing of surgery or rehabilitation following an MLKI surgery. This current review stresses the need for more high-level research to address the paucity of evidence-based treatment guidelines for the treatment of complex MLKIs.
