Arthroscopic Superior Capsular Reconstruction with Dermal Allograft following Structural Failure of a Rotator Cuff Repair

Description

In a recent presentation, Tan Thangarajah, a shoulder and elbow fellow in Calgary, discussed his work on evaluating the outcomes of Arthroscopic Superior Capsule Reconstruction (SCR) with dermal allograft in patients who experienced structural failure following prior rotator cuff repair. He began by thanking the BOSTAA selection committee for the opportunity to present this important research.



Thangarajah noted that around 40% of rotator cuff repairs fail, leading to complications when revision repairs are attempted, especially when the remaining tendon quality is inadequate. In such scenarios, SCR may be a viable treatment option, though limited reports exist on its use in post-repair failure cases. This study aimed to provide clarity on the effectiveness of SCR in these challenging situations.



The study included 24 male patients who had undergone SCR after experiencing structural failure of their initial cuff repairs. With standard rehabilitation protocols in place, outcomes were measured using the ASCS score and a work index, both indicators of functional improvement. Although many patients showed significant improvements in their scores, there was no corresponding enhancement in their range of motion.



One key finding emphasized by Thangarajah was that despite only 42% of the grafts appearing intact on subsequent MRIs, none of the retears required further surgical intervention during the two-year follow-up. Limitations included the lack of comprehensive functional outcome scores for all participants and the relatively short follow-up period.



In conclusion, the study suggests that arthroscopic SCR can effectively improve functional outcomes in patients with prior cuff repair failures, even though graft integrity may be limited. Thangarajah thanked his colleagues in Calgary for their support in this research project.
