We will randomly assign (randomize) study participants to either the bioengineered skin group or control group (compression therapy with a multilayered compression bandage). Regardless of the group to which a patient is assigned, we expect participation in this study for 12 months following the start of study treatment. We will examine each patient at the screening visit (2 weeks before randomization) and then again 3-4 days before the start of treatment to make sure the wound is free of any signs of infection. After the initial randomization visit we will examine the wound once a week for 24 weeks or until the wound heals, whichever is earlier. As soon as we have determined that the wound is completely healed, we will ask the patient to return once a month for 6 months to make sure it remains healed.
