Inside-out meniscus repair cohort is used to improve decision making

This study shows that gold-standard inside-out meniscus suture repair results in 10% repeated arthroscopy for lateral and 15% repeated arthroscopy for medial meniscus unhealed repairs. Lower failure rates are observed in concomitant ACLR, but isolated medial meniscus repair can result in 20% failure rates. These findings in addition to regaining closely preinjury activity levels, functional scores, and objective hopping and landing kinematics in the majority of the patients supports the concept "Save the meniscus", aiming to promote articular knee cartilage long-term healthiness. This is applicable also to populations over 40 and 50 years of age, particularly with concomitant ACLR. Machine-learning algorithms at the completion of this study may enable elaborating patient-specific decision-making protocol in order to improve surgical judgement.
