Efficacy of platelet-rich plasma injection in comparison to physical therapy for treatment of chronic partial supraspinatus tear

Abstract Background Supraspinatus tendon is a part of the rotator cuff shoulder, partial or full-thickness tear can affect secondary to trauma repeated microtrauma. The aim present study evaluate efficacy platelet-rich plasma (PRP) injection in comparison physical therapy for treatment chronic supraspinatus tears. Results At beginning study, there were no significant differences between both groups all parameters: (a) PRP had significantly improved visual analog scale (VAS), disabilities arm, shoulder and hand (DASH) range motion (ROM) but not size at 6 12 weeks post-injection baseline recordings; (b) VAS, DASH ROM nor (c) was superior improvement ROM, score. Conclusion US-guided improving pain, function thickness tendon.
