The Effect of Amniotic Membrane Injection as An Addition to Physical Therapy in Patients With Rotator Cuff Tear

The dehydrated AM product used in this study is derived from donated human placental tissue following healthy, live, caesarian section, full-term births which are then cleaned of blood under aseptic conditions. The product comes as a 20mg dry powder in a small vial stored at room temperature and mixed with 2 mL 0.9% sterile normal saline. Then the suspended AM will be injected to the injured tendon and the surrounding area with ultrasound-guidance via a 7cm, 23-gauge needle.

Physiotherapy includes hot pack, electric therapy and therapeutic exercise, which will be supervised by a senior physical therapist. The therapeutic exercise consists of active and passive stretching, and strengthening exercise of the rotator cuff, the shoulder girdle, and the pectoral muscles, and scapular stabilization exercise, 3 times a week, and will be continued for 12 weeks.
