Inclusion Criteria

Current inclusion criteria as of 16/04/2020:
1. > = 18 years or older (no upper age limit)
2. The ability to consent to participation
3. A diagnosis of venous leg ulceration* (defined as ‘colour duplex confirmation of superficial and or deep venous reflux with any break in the skin that has either: a) been present for more than 2 weeks, or b) occurred in a person with a history of venous leg ulceration)
4. A wound duration of at least 6 months
5. Documented venous incompetence on duplex ultrasound
6. Ulcer wound size > 2 cm2.
7. ABPI > = 0.8, or if the ABPI is incompressible, other forms of clinical assessment must exclude peripheral arterial disease (peripheral pulse examination, toe pressure, duplex ultrasound, clinical judgment)

*if more than one ulcer is present, the largest ulcer will be chosen as the reference ulcer for the purposes of the trial
