Features to Predict Success With Nonoperative Treatment of Patients With Rotator Cuff Tears

Rotator cuff tears are found in up to 40% of people over the age of 50 with the prevalence increasing with age. While most people remain asymptomatic, it is unknown why some develop symptoms. In symptomatic patients, surgical repair of a torn rotator cuff fails in 30-50% of patients, yet the majority of patients have a significant reduction pain despite failure of the repair. Nonoperative treatment has reported successful outcomes in 25-82% of patients yet it is not known which patient-related features predict success with nonoperative treatment. The general aim of this research effort is to identify patient features (historical information, physical examination findings, and MRI-based pathology) that would predict success (defined by reduction in visual analog pain scale, and patient satisfaction) with the nonoperative treatment of rotator cuff tears. The proposed study design is a prospective cohort study of patients with rotator cuff tears who will follow a standard physical therapy program derived from an evidence based medicine (EBM) systematic review of Level 1 and Level 2 studies. Study the effect of historical information on predicting success (as determined by pain relief and patient satisfaction) of nonoperative treatment using the EBM based physical therapy program in treating patients with rotator cuff tears. Study the effect of physical examination findings on predicting success of a nonoperative treatment using the EBM-based physical therapy program in treating patients with rotator cuff tears. Study the effect of the severity of the rotator cuff pathology (using standardized magnetic resonance imaging protocols) on predicting success of nonoperative treatment for patients with rotator cuff tears using the EBM-based physical therapy program.
