Revision Anterior Cruciate Ligament, Posterior Cruciate Ligament, and Medial Collateral Ligament Reconstructions With Primary Fibular Collateral Ligament Reconstruction After First-Stage Bone Grafting Procedure

Abstract:

Revision multiligament knee injuries are rare but can occur due to unaddressed injuries in the primary reconstruction, poor tunnel placement, or a new injury. A thorough examination via physical examination and imaging must be performed in a revision multiligament case, and occasionally, 2-stage procedures are required. This technical note describes revision anterior cruciate ligament, posterior cruciate ligament, and medical collateral ligament reconstructions after a first-stage bone grafting procedure with primary fibular collateral ligament reconstruction.

Technique Video:

Multiligament knee injuries involve 2 or more of the 4 major knee ligament complexes. The anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL)—the 2 main intra-articular structures—are the main restraints to anterior and posterior translation of the knee, respectively.1,2 The medial collateral ligament (MCL) and fibular collateral ligament (FCL)—the 2 main extra-articular structures—are the main restraints to valgus and varus gapping, respectively.3,4
Revision cases of multiligament knee injuries are rare but can occur due to new injuries, untreated initial injuries, or nonanatomic primary reconstructions.5 In revision cases, various factors including previous autografts used, previous tunnel placement, and bony alignment should be considered.5,6 This technical note describes revision ACL, PCL, and MCL reconstructions after a first-stage bone grafting procedure with primary FCL reconstruction.
