Prospective evaluation of arthroscopic rotator cuff repairs at 5 years: part I - Functional outcomes and radiographic healing rates

Background tor cuff registry was established to prospectively evaluate the effectiveness of all-arthroscopic repairs. This study reports those results at 5 years. als and methods udy enrolled 193 patients who underwent all-arthroscopic rotator cuff repairs. Patients were evaluated preoperatively and at 1, 2, and 5 years postoperatively. Outcome measurements included the American Shoulder and Elbow Surgeons (ASES) score, range of motion, manual muscle testing, and ultrasonography. s ears, 106 patients completed follow-up, representing 55% of the patients originally enrolled but 77% of those who returned for evaluation at 1 year. ASES scores improved from 52.6 ± 23.2 preoperatively to 92.6 ± 14.8 at 5 years (P < .001). Paired analyses showed no differences between the ASES scores at 2 and 5 years, but the scores improved from 1 to 5 years (P = .002). Between years 2 and 5, passive forward elevation decreased from 173° ± 10.3° to 168.6° ± 16.8° (P = .02) and external rotation decreased from 73.6° ± 21.3° to 67.8° ± 19.6° (P = .04). Patients improved a full motor grade in forward elevation and external rotation and this remained stable over time. The healing rates for all patients were 64.3% at 1 year, 75.4% at 2 years, and 81.2% at 5 years. Paired analyses showed increased healing rates from 1 to 5 years (P = .001) and from 2 to 5 years (P = .05). sion drange results of all-arthroscopic rotator cuff repairs are good, and functional results remain constant over 5 years. The ultrasound healing rates continued to increase with time; however, the mechanism and the clinical significance of this are uncertain at this time.
