Abstract

Background: Acromioclavicular (AC) joint trauma is a frequent sports injury. Modified Weaver Dunn (MWD) is a commonly used technique to address this injury. However, tendinous grafts (Autogenous Palmaris Longus or Semitendinosus tendons) are increasingly being used due to the biologic weakness of MWD.

Methods: Three search was done until January 2024 with data extraction consisting of adverse events (infections and failures), Constant-Murley score, American Shoulder and Elbow Surgeons score, and postoperative coracoclavicular distance.

Results: Four studies were included in this metaanalysis. Tendinous graft was shown to have statistically better ASES and Constant-Murley scores. Furthermore, there were no difference in adverse events, and postoperative coracoclavicular distance.

Conclusion: The tendinous graft showed no differences in adverse events, and postoperative coracoclavicular distance when compared to modified Weaver Dunn. However, it showed higher postoperative ASES and Constant-Murley score without analysis of the minimal clinical important difference making the difference solely statistical.

Level Of Evidence: 3.
