Clinical Trial Summary

The purpose of this study is to determine the efficacy and safety of compression bandaging with fractional ablative carbon dioxide laser (FACL) compared to compression and standard dressings alone for healing of post-operative wounds of the leg. This is a randomized, SMART design, clinical trial. Approximately 80 participants will be randomized to initially receive compression bandages or standard wound dressings after surgery on the lower leg. After 4 weeks, the group assigned to compression bandages will be further randomized to either continue with the compression bandages only or continue with the compression bandages and also receive (FACL). The study is designed as an 6-month study. This study was a pilot study designed to determine feasibility of these procedure. Subjects currently living in the Chicago metropolitan area and meet inclusion/exclusion criteria will be considered for enrollment.
