Summary
Arthroscopic superior capsular reconstruction (SCR) augmented rotator cuff repair (RCR) with dermal allografts significantly improves patient outcomes. While graft healing rates were 79%, MRI assessments showed poor interobserver agreement on graft integrity.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Regenerative Medicine
Background:
- Massive rotator cuff tears (RCTs) often involve poor-quality native tissue, complicating surgical repair.
- Arthroscopic superior capsular reconstruction (SCR) is an emerging technique to augment rotator cuff repair (RCR).
Purpose of the Study:
- To evaluate the clinical and radiographic outcomes of arthroscopic SCR augmentation for complete, massive rotator cuff repairs (RCRs) in patients with poor-quality rotator cuff tissue.
Main Methods:
- Retrospective review of 24 patients undergoing dermal allograft SCR-augmented RCR by a single surgeon.
- Clinical assessment included American Shoulder and Elbow Surgeons (ASES) scores, visual analog scale (VAS) for pain, and Subjective Shoulder Value (SSV) at 1 and minimum 2 years postoperatively.
- Postoperative MRI evaluated muscle quality (Goutallier classification) and graft/tendon integrity (Sugaya classification).
Main Results:
- Patient-reported outcomes significantly improved and were maintained at 2-year follow-up (ASES: 42.5 to 93.9; SSV: 30 to 90; VAS pain: 5.5 to 0).
- Postoperative MRI showed 79% graft healing (42% complete, 38% partial).
- Native supraspinatus and infraspinatus tendon healing rates were 42% and 54%, respectively, with poor interobserver agreement on MRI assessments.
Conclusions:
- Arthroscopic SCR with dermal allograft augmentation provides very good clinical outcomes for massive RCRs with poor tissue quality.
- Despite good clinical results, MRI assessment of graft and rotator cuff integrity demonstrated variability and poor interobserver agreement.
