Purpose: The current study assessed the factors affecting outcomes of primary repair procedures in tears of multiple rotator cuff tendons.
Materials and Methods: Among the cases of rotator cuff tears involving two or more tendons receiving operations between 1997 and 2003, The clinical results of 19 cases with more than 2 years follow-up were evaluated by the UCLA score. We evaluated the correlation of trauma, active motion, acromiohumeral distance, tear size, and surface area with the UCLA score using Pearson¡¯s linear correlation coefficient (PLCC).
Results: UCLA scores increased significantly in all cases, from 9 to 26.1 on average. However, the results were good in 53%, and poor in 47% according to Ellman¡¯s criteria. Trauma, active elevation, acromiohumeral distance, and tear size did not correlate with the UCLA score, but the tear surface area was inversely correlated with the score (PLCC=-0.696). Cases with degeneration of the infraspinatus muscle above Goutallier grade III on MRI showed worse results than cases with less degeneration.
Conclusion: The clinical results of primary repair of rotator cuff tears involving multiple tendons were satisfactory in 53% of patients. Large tear surface area and severe degeneration of the infraspinatus were poor prognostic factors.
