BACKGROUND AND PURPOSE The purpose of this study was to analyze midterm functional outcomes and tendon integrity in patients treated with in situ arthroscopic repair of Partial Bursal Rotator Cuff Tears (PBRCTs) without acromioplasty. MATERIAL AND METHODS Sixty two patients were included. Clinical assessment consisted of glenohumeral range of motion measurement and the American Shoulder and Elbow Surgeons (ASES) score. Pain was rated by using a visual analog scale (VAS). A postoperative ultrasound image control was performed at a minimum 5 years follow up to assess tendon integrity. RESULTS Mean age was 57.2 years (range, 44-77 years) and mean follow up was 7 years (range of 5-9 years). Significant improvements in range of motion, functional outcomes and pain were observed postoperatively (p < .0001). The ASES score improved from 46.5 to 90.2; and the VAS improved from 6.5 to 1.73 (p < .0001). Fifty six patients (90%) performed ultrasound evaluation at the end of follow up. Fifty-one patients (91%) presented tendon integrity on ultrasound. Five patients presented re-tears (9%). Three patients (5%) had a complete tendon re-tear and two patients (4%) had a partial re-tear. No difference in range of motion or functional outcomes were found between patients with intact tendon and those who had re-tears. CONCLUSIONS In the midterm follow-up, arthroscopic in situ repair PBRCTS without acromioplasty showed excellent functional outcomes and high healing rates in most patients with low complication rates.
