Purpose:To evaluate the functional and structural results of arthroscopic double-row repair using combined knot-tying and knotless suture anchors in rotator cuff tears.
Materials and Method :From March 2006 to June 2007, twenty-one patients (15 males, 6 females; mean age 55.6 years; range 48 to 67) were included who underwent arthroscopic double-row repair for full-thickness tears of the rotator cuff following conservative treatment for a mean of 6.5 months (range 3 to 11). The tear size was carefully inspected arthroscopically and we found 2 small, 13 medium and 6 large-sized rotator cuff tears, with a mean tear size of 2.5cm(range 1.8 to 3.2). The repair constructs were consisted of horizontal mattress sutures using conventional knot-tying suture anchors medially and simple suture at the same level of medial row stitch with Bioknotless RC anchors (DePuy Mitek, Norwood, MA) as lateral row. Clinical and functional evaluations were made according to the range of motion, the ASES, UCLA scale and the isokinetic strength testing. Postoperative cuff integrity was determined through magnetic resonance imaging. The mean follow-up was 15 months (range 13 to 24).
Results:The average clinical outcome scores and strength were all improved significantly at the time of the final follow-up (p < 0.01). Nineteen patients (90%) were satisfied with the result of the treatment. In 17 of 21 patients (81%) were judged to reveal healed tendon on magnetic resonance imaging at a mean of 7 months postoperatively. There were no significant functional differences according to the preoperative tear size (p<0.01), but large-sized tear shows less favorable structural results in 3 out of 6 cases(50%).
Conclusions:Our results document the usefulness and variability of arthroscopic double-row rotator cuff repairs comparable to the results of the other types of double-row repairs.
