Diabetes Related Foot Ulcers With Negative Pressure Wound Therapy

The goal of this study is to learn if the clinical effects of Negative Pressure Wound Therapy (NPWT) is better, worse or the same as standard wound care for patients with diabetic foot ulcers (DFUs). The main questions it aims to answer are: * Will there be a difference in the number of major amputations between the groups during the first year? * Will one of the treatments require more surgeries and longer hospital stays? All participants will: * be treated with NPWT or standard wound care for their diabetic foot ulcer after surgery * be followed closely at the out-patient clinic for one year after treatment
