What the study found
A 6 mm human dermal allograft in superior capsule reconstruction was associated with fewer lateral-sided graft tears and better functional outcomes than a 3 mm graft.
Why the authors say this matters
The authors conclude that thicker grafts in superior capsule reconstruction may lead to better functional results, because the 6 mm graft group had lower lateral-sided graft failure and better postoperative scores.
What the researchers tested
The study compared patients who underwent superior capsule reconstruction with either a 3 mm graft or a 6 mm graft at a single institution. The researchers recorded age, sex, Hamada grade, acromiohumeral distance, American Shoulder and Elbow Surgeons (ASES) score, Oxford score, visual analog scale (VAS) for pain, and postoperative single-assessment numeric evaluation score, and they obtained postoperative magnetic resonance imaging regardless of symptoms.
What worked and what didn't
Both groups improved significantly in ASES, Oxford, and VAS scores. However, there was no difference in acromiohumeral distance after surgery in either group, while the 6 mm group had better postoperative ASES, Oxford, VAS, and single-assessment numeric evaluation scores, as well as lower graft tear rates and lower lateral-sided graft failure.
What to keep in mind
This was a retrospective comparative study from a single institution with a minimum follow-up of 1 year. The abstract does not describe other limitations beyond the study design and follow-up scope.
Key points
- The study compared superior capsule reconstruction using 3 mm versus 6 mm human dermal allograft.
- The 6 mm group had lower graft tear rates than the 3 mm group.
- Lateral-sided graft failure was lower in the 6 mm group.
- Both groups improved in ASES, Oxford, and VAS scores after surgery.
- Postoperative ASES, Oxford, VAS, and single-assessment numeric evaluation scores were better in the 6 mm group.
