The incidence of Partial Rupture of the Rotator Cuff (PRRC) in the general population is high, ranging from 15% to 32%. Therefore, this kind of rupture has a high impact on health systems. PRRC healing does not occur spontaneously, or through non-anatomical procedures, such as open or arthroscopic acromioplasty, which has shown to be ineffective for healing or preventing the progression of the lesion. The study was carried out with patients from the Ambulatory of Regenerative Medicine of the Center for Studies on Tissue Regeneration (CERT), with partial lesions of the supraspinatus tendon and pain. The study consisted of 26 joints (shoulders) of 24 patients, aged between 28 and 79 years (average of 51 years). The treatment was based on a technique which consisted of an injection of 5 mL of subacromial Xylocaine (1% without constrictor vessel) followed by 10 perforations of the tendon injury area using a 22 G (0.70 mm × 25 mm) needle, and a peritendinous injection of 6 mL of platelet rich plasma guided by ultrasound. Comparative analysis of pre and post treatment images was performed. Post-procedure evaluations were performed, when patients responded questionnaires to assess quality of life and reported the percentage of pain improvement. All patients included in the study, presented partial lesions of the supraspinatus tendon, with an average size of 7.68 mm. The lesion healing was measured by ultrasonography, with significant difference between the pre-treatment and post-treatment measure.
