A chronic leg ulcer is defined as a defect in the skin below the knee that has persisted for more than two weeks and shows no sign of healing after three or more months (NHS, 2019). Lower limb and leg ulcer management presents a number of global health challenges in terms of nursing resources, wound care dressings and high recurrence rates. Also, the persistence and recurrence of lower limb conditions can lead to physical and emotional distress for individuals and their families, contributing to depression, lack of esteem, self-neglect, social isolation and loss of income.
