Optimizing Anterior Cruciate Ligament (ACL) Outcomes: What Else Needs Fixing Besides the ACL?

Instr Course Lect 2020 ;69:653-660

This review focuses on the management of anterior cruciate ligament (ACL) reconstruction patients when other concomitant pathology may need to be addressed at the time of surgery. Given the role of the posterior horn of the medial meniscus in preventing osteoarthritis progression and contributing to knee stability, medial meniscus repair should always be considered when performing ACL reconstruction. Meniscal transplant may also be appropriate in select patients with normal knee alignment and absent of cartilage abnormalities in the compartment. Read More

Editorial Commentary: Variations of National Health Systems: Time From Injury to Surgery Can Affect Anterior Cruciate Ligament-Medial Collateral Ligament Treatment Outcomes.

Authors:
Mark G Siegel

Arthroscopy 2020 01;36(1):212-213

A recent investigation using the Swedish National Knee Registry large database showed that "The risk of ACL revision did not differ between HT and PT autografts in patients undergoing ACL reconstruction with a non-surgically treated MCL injury. However, the use of ST-G was associated with poorer two-year patient-reported knee function compared with the ST." However, the Swedish Health care system is so unique that the results may not be universally applicable. Read More
