Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 19 and older with unilateral shoulder pain lasting over three months and confirmed partial-thickness rotator cuff tears.

Probably not a fit

Patients with complete rotator cuff tears or those who have had recent shoulder surgeries or injections may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the safety and efficacy of allogenic umbilical cord-derived mesenchymal stem cells in patients suffering from rotator cuff disease. Participants will receive injections of these stem cells to assess their potential in alleviating shoulder pain and improving function. The study targets individuals who have not found relief from conservative treatments and have confirmed partial-thickness rotator cuff tears. It aims to provide a novel therapeutic option for those with chronic shoulder pain.

Why it matters

Potential benefit: If successful, this treatment could offer a new, effective option for patients with persistent rotator cuff disease who have not responded to traditional therapies.

How similar studies have gone: While the use of stem cells in orthopedic conditions is an emerging field, this specific approach has not been widely tested, making it a novel investigation.
