Abstract
Background: Although arthroscopic repairs of the rotator cuff are becoming increasingly popular, security of fixation remains a concern. Two-row repairs have been described, but clinical outcome reports have primarily involved open techniques. Hypothesis: An arthroscopic repair technique that uses 2 rows of fixation produces satisfactory outcome and structural integrity by ultrasonography. Study Design: Case series; Level of evidence, 4. Methods: Forty-eight patients (52 shoulders) with a full-thickness, but fully reducible, rotator cuff tear who met the inclusion criteria were treated with an arthroscopic rotator cuff repair using 2 rows of suture anchors. The mean tear size was 2.47 cm (range, 1-4 cm). Patients were evaluated by subjective functional assessment (L'Insalata Shoulder Rating Questionnaire), clinical examination, including measured strength testing, and ultrasonography. Results: At a mean follow-up of 30 months (minimum of 2 years), functional scores improved from a mean of 42 preoperatively to 93 postoperatively (P <. 001). Active range of motion was increased in all measured planes (P <. 001). Strength was also increased in elevation (P <. 001), external rotation (P <. 001), and internal rotation (P =. 033). Nine of the 52 shoulders (17%) had evidence of retear or persistent defect on postoperative ultrasonography. There were no differences detected in functional scores between those with an intact repair and those with a defect, but those with an intact repair were stronger in elevation (P =. 006) and external rotation (P =. 001). Conclusion: An arthroscopic 2-row rotator cuff repair produces excellent functional outcome and repair integrity comparable with previously reported open repairs. Presence of a defect after repair did not appear to affect patient-reported function and return to preinjury activity but did affect measured strength.Keywords
