The classification system introduced by Meggitt in 1976 and later popularized by Wagner in 1979 was once widely adopted. It operates on a six-grade scale, primarily assessing ulcer depth and tissue necrosis level. While this wound-centric system is straightforward and easy to apply, it lacks consideration for crucial clinical factors like peripheral neuropathy and peripheral arterial disease (PAD). As a result, it struggles to differentiate between infected and ischemic ulcers, leading to acknowledged imprecision and limitations.
