Abstract
OBJECTIVE: While some patients may require surgical treatment a lot of patients do recover on conservative treatment alone while the optimal treatment being unclear. The purpose of this study was to treat the PT-RCTs conservatively for a period of 6 months and to determine its clinical outcome, radiological outcome on MRI and the baseline clinical factors predictive of that outcome. METHODOLOGY: All patients with a partial tear of supraspinatus and/or infraspinatus on their 1st MRI and aged 18-80 years were eligible and 47 patients (22 males, 25 females) were enrolled. Patients were evaluated using a standardised format including clinical history, imaging, and ASES(American Shoulder and Elbow Surgeons) score. Patients underwent a course of physical therapy for a period of minimum of 6 months which was augmented with the use of analgesics and/or anti-inflammatory drugs, multivitamins and supplements which were patient specific. Patients were followed up at 3 months and 6 months, ASES score was calculated, and a follow-up MRI was done at 6 months to determine if their tear had healed, remained the same, or progressed. A patient that had a better ASES score at 6 months was tagged as "clinically improved". Radiologically, patients were considered treated "successfully" if the tear size was reduced or remained the same while some "failed" that had an increased size of tear. RESULT: Non-operatively treated patients demonstrated a mean ASES score of 63.45 ± 16.24 at the end of 6 months. Overall, 35 patients (74.5 %) had the same size, seven patients (14.9 %) demonstrated tear progression and 5 (10.6 %) patients showed a decrease in size of their tear on MRI done at 6 months. In the end, 30 (63.8 %) patients improved clinically and 40 (85.1 %) patients improved radiologically. Statistical analysis also showed that patients with their non-dominant side involved and with an atraumatic onset of their injury were more likely to improve clinically. CONCLUSION: Conservative treatment of PT-RCTs may lead to a successful clinical outcome but it may or may not reveal itself radiologically. ASES score is an effective tool to evaluate and manage various conditions of the shoulder and not just the rotator cuff. The baseline factors such as onset (traumatic versus atraumatic) and shoulder involved (dominant versus non-dominant) can predict the outcome of conservative treatment.
