The Efficacy of PRP Injection in the Treatment of Rotator Cuff Syndrome

"In single-PRP injection group, 10 ml of venous blood taken from the patients will be put into the T-LAB® PRP kit (T-Biotechnology Laboratory, İstanbul, Turkey) and will then be centrifuged at 3850 rpm for 8 minutes. Approximately 4 ml of the PRP obtained will be injected into the subacromial space using the lateral subacromial injection method under ultrasound guidance. All injections will be performed in the sagittal axis with the long axis in-plane technique, using the ultrasound device (Esaote My Lab 70 XVision 6-18 Mhz linear probe).~A physical therapy program including Codman pendulum exercises, shoulder range of motion, stretching and strengthening exercises will be given and be performed at least for 20 minutes daily."

"In multiple-PRP injection group, two PRP injections will be performed with an interval of 3 weeks. 10 ml of venous blood taken from the patients will be put into the T-LAB® PRP kit (T-Biotechnology Laboratory, İstanbul, Turkey) and will then be centrifuged at 3850 rpm for 8 minutes. Approximately 4 ml of the PRP obtained is planned to be injected into the subacromial space using the lateral subacromial injection method under ultrasound guidance. All injections will be performed in the sagittal axis with the long axis in-plane technique, using the ultrasound device (Esaote My Lab 70 XVision 6-18 Mhz linear probe).~A physical therapy program including Codman pendulum exercises, shoulder range of motion, stretching and strengthening exercises will be given and be performed at least for 20 minutes daily."

"In placebo-injection group,10 ml of venous blood will be taken and after the same waiting time 4 ml of 0.9% saline will be injected into the subacromial space using the lateral subacromial injection method under ultrasound guidance. All injections will be performed in the sagittal axis with the long axis in-plane technique, using the ultrasound device (Esaote My Lab 70 XVision 6-18 Mhz linear probe).~A physical therapy program including Codman pendulum exercises, shoulder range of motion, stretching and strengthening exercises will be given and be performed at least for 20 minutes daily."
