About this study
Rotator cuff tear (RCT) is a commonly seen pathology in shoulder disease, which causes significant disability in daily living and work. Based on a cohort study of a large population, the prevalence of rotator cuff full-thickness tear was 20.7%. More broadly, the prevalence of rotator cuff abnormalities increased with age and up to 62% in population more than 80 years old. The pathophysiology of RCT could be attributed to extrinsic factors such as impingement by surrounding tissue and intrinsic factor such as tendon degeneration. According to previous study using histochemical and immunocytochemical techniques, fibrocartilaginous metaplasia, decreasing vascularity and fibroblast numbers were found in rotator cuff tear. Besides, the inflammatory response diminished as the tear size increased.
The treatment of RCT includes surgery and non-operative treatment. The prognosis depends on the symptoms, tear size, chronicity and other structures involvement. Previous meta-analysis study reported that the effectiveness between surgery and conservative treatment is similar in treating RCT. Therefore, relative rest, oral medication, physical therapy and injection therapy were commonly used in first-line treatments. When treating shoulder pain with injection therapy, steroid was often used at first for short-term pain relief and anti-inflammation. However, the potential cytotoxic effect was found and could be harmful in tendon repair. To accelerative the healing process of soft tissue injury, regenerative injection become more popular and expectable over past few years. A meta-analysis study reported the positive long-term effect of prolotherapy and platelet-rich plasma (PRP). More recently, bone marrow concentrate (BMC) and amniotic membrane (AM) have been used in soft tissue repair and many clinical studies are processing.

In recent decades, PRP was widely used in soft tissue regeneration. Though many studies had discussed the effect of PRP injections on pain and shoulder function in RCT, the effectiveness remains controversial. Some newer scaffolds including bovine collagen and amnio-derived membranes were also applied to the RCT in recent years. The AM was separated from a donor's placenta, and is a non-immunogenic structure. In previous animal study, amniotic epithelial cells could produce transforming growth factor-β (TGF-β), basic fibroblast growth factor (bFGF), epidermal growth factor (EGF), transforming growth factor-α (TGF-α), keratinocyte growth factor and hepatocyte growth factor. AM was found having anti-inflammatory, antimicrobial, antiviral effect, regulatory effect on angiogenesis and anti-scarring effcts. AM was revealed a pluripotent tissue which makes it potential in regenerative medicine. In some case series research, positive results was reported in pain and shoulder function in rotator cuff tears.
To the best of our knowledge, there has been limited evidence of regenerative injection by AM in treating patients with rotator cuff tear. The aim of this study is to evaluate the effect of single injection of AM in addition to physical therapy on pain and shoulder function.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Amniotic membrane preparation and injection (AM group)Other
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 (PT group)Other
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Pain Visual Analogue Scale (VAS)
The pain VAS during Neer test will be obtained using a horizontal line of 100 mm, with 0 on the left indicating no pain and 100 on the right indicating very severe pain. A pain VAS has been shown to be reliable and sensitive for quantifying pain, with test-retest reliability of >0.90.24 In previous studies of patients treated for various shoulder disorders, the responsiveness of VAS for pain was moderate to good.
Measured: change between baseline and at 4 weeks, 12 weeks, and 24 weeks after the beginning of the treatment.
Secondary outcomes (1)
Shoulder Pain and Disability Index (SPADI)
The SPADI is a self-administered questionnaire to assess the pain and disability associated with shoulder diseases. It consists of 13 items being divided into 2 subclasses, 5 items for pain and 8 items for disabilities. The total SPADI score, which ranges between 0 and 100, is calculated by averaging the scores from the pain and disabilities subclasses. Good validity and reliability had been proved in previous studies.
Measured: change between baseline and at 4 weeks, 12 weeks, and 24 weeks after the beginning of the treatment.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pain Visual Analogue Scale (VAS) (time frame: change between baseline and at 4 weeks, 12 weeks, and 24 weeks after the beginning of the treatment.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Apr 2024.
