Primary repair of proximal anterior cruciate ligament injury: a global expert consensus statement

The application of primary repair for anterior cruciate ligament (ACL) injuries remains controversial, and evidence-based guidelines have not yet been established. Remarkable advancements in arthroscopic techniques and biological stimuli have been achieved in the past decades, which may change expectations regarding the potential of ACL healing and clinical outcomes for patients. In this study, a global expert consensus on the primary repair of proximal ACL injuries was established. A panel of 16 experts from the fields of sports medicine and arthroscopic surgery was invited to participate in the compilation of this consensus statement. This project followed the Delphi approach to the consensus process involving steering, rating, and peer review groups. Ultimately, 14 statements were retained: four achieved unanimous support, six achieved strong consensus, and four did not achieve consensus. The expert consensus statement established in this study focused on surgical indications, decision-making, surgical techniques, adjunctive methods, prognostic factors, and rehabilitation following ACL repair. The accepted recommendations in these areas will assist doctors and therapists in standardizing the management of related pathologies. The consensus statement clearly states that the tear site and tissue quality are important for ensuring successful ACL repair, while other factors should also be considered. ACL reconstruction remains the gold standard for ACL repair until long-term follow-up data demonstrates otherwise.
