This is a non-randomized clinical trial conducted in a single tertiary hospital which investigates the efficacy of allogeneic adipose-derived mesenchymal stem cells and human amniotic membrane (AAdMSC-HAM) composite for supraspinatus tendon repair augmentation


Supraspinatus tendon tear is the most common factor causing shoulder pain, mainly resulting in discomfort and functional deficit in individuals over the age of 35. Supraspinatus tendon repair surgery represents one of the most widely performed types of orthopedic operation. Nevertheless, concerns persist regarding tendon-to-bone healing during the postoperative period. Despite advancements in surgical technique, re-tear of a previously repaired supraspinatus tendon is a fairly common complication, especially in a larger size tear. Such repair technique employing suture anchor devices alone has not yet produced functional results demonstrating both anatomical and biomechanical properties. Therefore, tendon tissue engineering using a combination of scaffolds, cells, and growth factors stimulation offers a potential solution as a biological augmentation in tendon repair.

Human amniotic membrane (HAM) has been widely used as a natural scaffold in tissue engineering due to many of its unique properties such as providing growth factors, cytokines and tissue inhibitors of metalloproteinases, adequate mechanical strength, and biocompatibility. Whereas, mesenchymal stem cells (MSCs) constitute one of the adult stem cells that promote replacement and repair of damaged tissue along with normal tissue turnover. These MSCs are seeded to the HAM scaffolds to biologically augment tendon repair, with MSCs acting as cytokines/growth factors to stimulate tissue repair. This approach serves as the foundation to conduct the present study. The investigators aim to investigate the efficacy of using allogeneic adipose-derived MSCs and human amniotic membrane (AAdMSC-HAM) composite for supraspinatus tendon repair augmentation.
