A Retrospective, Observational Study of the Real-world Safety and Performance of InnovaMatrix® AC at a Single Centre

Inclusion Criteria: * Male and female subjects aged 18 years or older at the time the data were reported. * Subjects with hard-to-heal wound(s), defined as those that have failed to show improvement (which is defined as ≥50% reduction in wound area) over 4-weeks of standard wound care. * Initial Wound area that is \>0.5 cm2 and \<10 cm2 * InnovaMatrix® AC applied to target wound(s) for a minimum of two consecutive weekly visits inside a 4-week period. * Subjects were compliant with wound protection strategies through treatment period (offloading, compression, etc). * The target wound(s) is not undergoing active management at the time of data entry. Exclusion Criteria: * Wound area showed ≥50% reduction in 4-weeks preceding initial InnovaMatrix® AC application. * Cases where InnovaMatrix® AC was not applied at a minimum of two consecutive weekly visits inside a 4-week period. * Subjects who were non-compliant with additional wound protection strategies (offloading, compression, etc) * Subjects with severe comorbidities that significantly impact healing ability, or ability for subject to be compliant with wound protection strategies, such as: peripheral vascular disease (ABI \<0.4, \>1.3)1, severely uncontrolled diabetes (Hgb A1C \>9.0%), neurodegenerative disorders, Charcot foot, high dose corticosteroid or other immunosuppressant, etc * Wound area \<0.5 cm2 or \>10 cm2 * The target wound is still under active treatment.
