Rotator cuff tears are extremely prevalent in the general population, and many patients with rotator cuff tears can be treated successfully without surgical intervention. Little data exists in the literature regarding patient and pathology related factors which predict the outcomes after nonsurgical management.
By evaluating the patient reported outcomes in a cohort of patients who underwent nonsurgical management for full-thickness rotator cuff tears, we hope to uncover important factors which may refine treatment indications for this subset of patients.
The objectives of this study were to evaluate the outcomes of nonsurgical management in patient with full thickness rotator cuff tears, and to identify patient and tear related characteristics which may predict outcomes. These findings could have a significant impact on the treatment of patients with rotator cuff tears in the future.
Patients in our institutional registry who underwent nonsurgical management for full thickness rotator cuff tears were identified. Pre-treatment magnetic resonance imaging scans were evaluated for tear size and related muscle atrophy and fatty infiltration. Patient reported outcomes were evaluated at 1 and 2 years after treatment began and regression analyses were performed in order to identify any predictors of patient reported outcomes in this cohort.
Patient reported outcome measures improved significantly at 1 and 2 year follow up after nonsurgical management. Patients who presented with chronic symptoms showed less improvement in patient reported outcome scores, and those with traumatic tears were noted to make greater improvements over the course of the study.
Patients with full thickness rotator cuff tears can achieve significant clinical improvement with nonsurgical management. Several factors may affect the amount of improvement they achieve, including the duration of their symptoms at presentation and the mechanism of their pain at the onset of symptoms. Additional factors likely exist that may impact patient outcomes in the setting of rotator cuff pathology.
Future studies should consider additional factors that may be relevant in predicting outcomes in patients with rotator cuff tears including pertinent physical exam findings and concomitant shoulder pathology such as biceps tendon involvement. Prospective comparative studies of surgical and nonsurgical management will also help clarify the ideal surgical and non-surgical indications in this cohort of patients.
