Compared with the combination of double-layer artificial dermal repair materials combined with growth factors, and the treatment methods using double-layer artificial dermal repair materials, the time and effect of the two treatment regimens on the function and appearance of wound repair with exposed tendon were different, as well as the medical costs.
This study used a prospective cohort study to select all patients who met the inclusion criteria in six hospitals within six months after the start of the trial, including no less than 55 patients receiving artificial dermis combined with growth factor and no less than 110 patients receiving simple artificial dermal treatment, and the cumulative number of patients was not less than 110 patients, to compare the time and effect of the two treatment options on the functional and cosmetic restoration of upper limb wound repair with exposed tendons.
Study Type
OBSERVATIONAL

Wound closure evaluation
After transplantation of the autologous epidermis, it takes for the exposed tendon wound to heal 100%.
Time frame: Two successive observations confirm the time when the wound is completely closed
Wound closure evaluation
One week after transplantation of the autologous epidermis, the survival rate of skin grafting on the exposed tendon wound is localized.
Time frame: 7 days after the patient implanted the autologous blade thick skin tablet
