Editorial Commentary: Anterior Cruciate Ligament Repair Could Be Indicated in Older, Less Active Patients.

Anterior cruciate ligament (ACL) injuries do not heal anatomically on their own and often lead to post-traumatic osteoarthritis (PTOA). ACL reconstruction, though effective, can contribute to PTOA, and donor site morbidity remains a concern with autografts. While ACL repair has traditionally shown poorer outcomes (27% failure rate in the 1990s and early 2000s), a recent review of newer techniques shows promising results and no significant differences in patient-reported outcomes between repair and reconstruction. Today's repair and augmentation methods are more advanced than those used 20 to 30 years ago; technologies like bridge-enhanced ACL repair and dynamic intraligamentary stabilization appear more promising than simple suture augmentation. Biological concerns, particularly the inability of the ACL to mount a healing response due to the rupture of its synovial envelope, have been addressed most effectively by the bridge-enhanced ACL repair method, with studies showing promising results in animal models and human trials. A better understanding of tear patterns and ACL bundle anatomy has also enhanced our ability to identify suitable candidates for repair. ACL repair techniques could help reduce the inflammatory response that accelerates PTOA after ACL injury and surgery. This makes repair a potentially attractive option for certain patients, particularly older or less active individuals who may not need a traditional ACL reconstruction. Still, caution is required. I believe young, active athletes should still be treated with traditional autograft reconstruction, as repair techniques have not yet proven superior in this group, with failure rates of 20% to 30%.
