A Novel Machine Learning Model to Predict Revision ACL Reconstruction Failure in the MARS Cohort.
Orthop J Sports Med
November 2024
Background: As machine learning becomes increasingly utilized in orthopaedic clinical research, the application of machine learning methodology to cohort data from the Multicenter ACL Revision Study (MARS) presents a valuable opportunity to translate data into patient-specific insights.
Purpose: To apply novel machine learning methodology to MARS cohort data to determine a predictive model of revision anterior cruciate ligament reconstruction (rACLR) graft failure and features most predictive of failure.
Study Design: Cohort study; Level of evidence, 3.
Surgical Predictors of Clinical Outcome 6 Years After Revision ACL Reconstruction.
Am J Sports Med
November 2024
Background: Revision anterior cruciate ligament (ACL) reconstruction has been documented to have inferior outcomes compared with primary ACL reconstruction. The reasons why remain unknown.
Purpose: To determine whether surgical factors performed at the time of revision ACL reconstruction can influence a patient's outcome at 6-year follow-up.
This work is focused on designing an easy-to-use novel perfusion system for articular cartilage (AC) tissue engineering and using it to elucidate the mechanism by which interstitial shear upregulates matrix synthesis by articular chondrocytes (AChs). Porous chitosan-agarose (CHAG) scaffolds were synthesized and compared to bulk agarose (AG) scaffolds. Both scaffolds were seeded with osteoarthritic human AChs and cultured in a novel perfusion system with a medium flow velocity of 0.

Purpose: To determine if meniscal and/or articular cartilage pathology at the time of revision ACL surgery significantly influences a patient's outcome at 6-year follow-up.
Study Design: Cohort study; Level of evidence, 3.
Article Synopsis
- The study investigates the differences in preoperative characteristics, intraoperative findings, and outcomes after two years for patients undergoing revision ACL reconstruction (rACLR) with and without bone grafting.
- Out of 1,234 patients analyzed, 159 (13%) required bone grafting, with variables including the type of grafting (1-stage or 2-stage) affecting preoperative quality of life and activity levels.
- Patients needing 2-stage grafting had undergone more previous ACL surgeries and were less likely to have used certain types of grafts in their initial surgeries compared to those who did not require grafting.
