Long-term outcomes after arthroscopic transosseous-equivalent repair: clinical and magnetic resonance imaging results of rotator cuff tears at a minimum follow-up of 10 years.

The objective of this study was to evaluate the long-term functional outcomes and structural integrity of medium to massive rotator cuff tears at 10-12 years of follow-up after arthroscopic transosseous-equivalent (TOE) repair. This was a retrospective study of a consecutive series of patients who underwent primary arthroscopic TOE repair of medium- to massive-sized degenerative rotator cuff tears performed by a single surgeon between January 2007 and August 2009. Patients were examined at a minimum follow-up of 10 years, and magnetic resonance imaging (MRI) was performed to assess tendon integrity. The Constant score (CS), American Shoulder and Elbow Surgeons score, and pain level documented using a visual analog scale were compared between intact repairs and recurrent defects. Univariate analysis was performed to identify factors related to recurrent defects. A total of 102 patients met the inclusion criteria, and 79 shoulders in 76 patients (74.5% of eligible patients) with a mean age at surgery of 55 ± 8 years (range, 40-72 years) were available for clinical evaluation at a mean follow-up time of 10.9 years (range, 10-12 years). The mean anteroposterior tear size was 3.1 ± 1.1 cm, and there were 41 medium (52%), 26 large (33%), and 12 massive (15%) tears. MRI was performed in 72 shoulders in 69 patients (91% of available shoulders) and revealed that 13 shoulders had recurrent defects (Sugaya stages 4 and 5). During the follow-up period, 3 patients underwent revision surgery, and the overall recurrent defect rate was 21.3%. A clinically meaningful improvement was observed in all outcome measures at the final follow-up regardless of tendon integrity. Patients with intact repairs showed superior outcomes compared with those with recurrent defects; however, only the overall CS met the threshold for clinical relevance. A significant linear correlation was observed between the Sugaya classification and all outcome scores except the CS pain subscale; however, the strength of correlation was weak. The presence of diabetes (odds ratio [OR], 8.6; 95% confidence interval [CI], 2.25-33.2; P = .002), tear size (OR, 2.08; 95% CI, 1.16-3.46; P = .012), and tear retraction (OR, 4.07; 95% CI, 1.11-14.83; P = .033) were associated with recurrent defects in the univariate analysis. Arthroscopic TOE repair of rotator cuff tears provided improved clinical outcomes with a recurrent defect rate of 21.3% at 10-12 years after surgery. Future research focusing on tendon healing is needed as repair integrity on MRI correlates with clinical outcomes.
