What to Do When It Is Anterior Cruciate Ligament Reconstruction Number Two.

Several factors contribute to the greater complexity of revision anterior cruciate ligament reconstruction compared with primary anterior cruciate ligament reconstructive surgery. Prior tunnels and hardware may compromise revision tunnel placement and secure fixation. This may necessitate two-stage revision or specific techniques to achieve anatomic revision tunnels. Prior autograft use may limit graft options. Individuals with a failed anterior cruciate ligament reconstruction are more likely to have risk factors for further failure. These may include malalignment, occult instability, knee hyperextension, or increased tibial slope. There are also higher rates of meniscus and cartilage injuries in revision anterior cruciate ligament reconstruction that may require intervention. Successful revision anterior cruciate ligament reconstruction requires thoughtful preoperative planning along with multiple potential intraoperative plans depending on the pathology encountered. It is important to provide the orthopaedic surgeon with an up-to-date, evidence-based overview of how to approach and execute a successful revision anterior cruciate ligament reconstruction.
