A Novel, Fast, Safe, and Effective All-Inside Arthroscopic Rotator Cuff Repair Technique: Results of 1000 Consecutive Cases

Background: Arthroscopic rotator cuff repair is a common but technically difficult surgical technique. This study describes a novel arthroscopic rotator cuff repair technique where the repair was performed while visualized entirely from the glenohumeral joint. A single-row knotless tension band inverted mattress suture technique was utilized with fixation obtained via suture anchors. The technique was relatively easy to perform and demonstrated good repair strength and footprint compression in an ex vivo ovine model. Purpose: To evaluate the safety and efficacy of this technique in 1000 consecutive patients. Study Design: Case series; Level of evidence, 4. Methods: This study was a retrospective analysis of prospectively collected data in 1000 consecutive patients. Included patients underwent primary arthroscopic rotator cuff repair by a single surgeon performing the undersurface repair technique and attended 6-month follow-up with ultrasound evaluation to determine repair integrity. Exclusion criteria were irreparable tears, incomplete repairs, tendon reconstruction with a synthetic patch, and revision cases. Results: The only complication was retear. The overall retear rate at 6 months following repair with the undersurface technique was 8.5%. The mean +/- SEM operative time for the technique was 16 +/- 0.3 minutes (range, 4-75 minutes). There were no infections. Smaller tears were repaired faster and had better healing rates. Conclusion: The novel all-inside arthroscopic rotator cuff repair technique was safe and significantly faster and provided better healing rates than other repair techniques. The retear rate of 8.5% is, to the authors' knowledge, the lowest reported rotator cuff retear rate in a large cohort of patients based on a single technique.
