AANA25 Knee Access Pass-CONCURRENT SESSION 2B: Knee Papers

Video Transcription

Video Summary

The knee paper session covered diverse studies on ACL reconstructions, meniscus repairs, biomarker research, and multi-ligament knee injury management. Dr. Economopoulos presented on ACL reconstruction in female soccer players, showing that adding lateral extra-articular tenodesis (LET) reduces graft failure and residual rotational instability without impacting graft tear rates or return to play outcomes. LET complications were low and manageable.<br /><br />Dr. Baumgarten discussed the Bayer bridge-enhanced ACL restoration (BARE) procedure, highlighting higher knee instability post-surgery compared to uninjured knees at one year, with ongoing follow-up needed to evaluate long-term outcomes.<br /><br />Daniela Coracoa emphasized that passing return-to-sport tests post-ACL reconstruction is linked to lower re-rupture rates, suggesting these tests help objectively assess functional readiness though further research with larger cohorts is required.<br /><br />A cadaveric study on internal brace use in PCL repair found it reinforced stability without over-constraint, with sequential tensioning (internal brace first) providing a favorable stability differential.<br /><br />Dr. Van Der List's study showed age was not predictive of failure or outcomes after medial meniscus root repair, though larger datasets are needed to assess other factors like chondromalacia.<br /><br />Lathe and colleagues demonstrated synovial fluid pro-inflammatory biomarkers at meniscectomy correlated with worse outcomes and higher total knee arthroplasty rates, indicating biomarker profiling could identify high-risk patients for targeted therapies.<br /><br />Scott Feeley presented that biointegrative screws for tibial tubercle osteotomy fixation yielded similar union and complications but dramatically reduced hardware removal rates compared to metal screws, though with higher implant costs.<br /><br />Clay Noelle showed fresh meniscal allograft transplantation led to 91% graft survival and improved patient outcomes at four years, suggesting viable grafts may mitigate early failure seen with frozen tissue.<br /><br />Dustin Richter outlined an algorithmic approach for multi-ligament knee injuries emphasizing multidisciplinary care, single-stage treatment, meticulous graft preparation, timing considerations, and techniques to minimize tunnel collision.<br /><br />Overall, the session highlighted innovations in surgical techniques, biomechanics, biomarkers, and rehabilitation protocols aimed at improving knee injury outcomes, emphasizing the importance of patient-specific strategies, biomechanical understanding, and objective functional assessments.
