Editorial Commentary: Remember the Risk Factors During Individualized,Anatomic, Value-Based Anterior Cruciate Ligament Reconstruction

Understanding the etiology behind anterior cruciate ligament (ACL) reconstruction failure is a complex topic still being investigated heavily. The 3 classes of failure are technical, traumatic, and biologic. Technical errors are most common and most frequently reflect tunnel malposition. In addition, tibial slope has long been understood to be a risk factor for failed ACL reconstruction. Although not routinely performed at time of primary ACL reconstruction, osteotomy may be considered in the setting of failed ACL reconstruction. Relative quadriceps weakness is a risk factor, and we recommend sport-specific return-to-play testing as well as benchmarks for relative quadriceps strength before full return to activity. Revision ACL reconstruction is associated with both increased costs and worse patient outcomes, so every effort should be made to give patients the best chance of success after the index surgery. Whereas this begins with understanding the patient’s history and risk factors for failure, it crescendos with careful attention to the individually variable factors that make each case unique, tailoring one’s management to ensure that each patient receives an anatomic, individualized, and value-based ACL reconstruction.
