Abstract
Introduction
Ankle replacement is a major surgery with significant soft tissue dissection and bleeding. The skin quality is often poor in these patients due to age, edema, venous congestion, arteriopathy or previous procedures and soft tissue injury. The chances of wound infection increase with delayed wound healing. Absorbent non-adherent dressing (ABD) and VAC dressing applied in theatre after ankle replacement were assessed in a cohort of 147 patients with wound complications, pain, satisfaction and length of stay as outcome measures.
Patients and methods
71 consecutive patients were treated with ABD post-operatively after ankle replacement. The practice was then changed to VAC dressings for 76 consecutive patients. 44 patients had additional procedures performed with ankle replacement (11 from ABD group and 33 from VAC group). Retrospective analysis of prospectively collected data was performed. All patients had daily pain score, wound status, hospital stay, satisfaction and range of movement recorded.
Results
Patients with VAC had mean pain score of 3/10 post operatively compared with 6/10 with ABD. There was a significant difference between the length of stay between the groups (p=0.02). The average stay of stay was 9 days with ABD and 7 days with VAC dressing. One of the patients with VAC dressing had blisters and 1 patient developed a superficial wound infection. Of the ABD group, 3 patients developed blisters and 7 patients had wound complications after ABD. Range of movement was similar in both groups of patients. Patient's satisfaction with VAC dressing was 8/10.
Conclusion
VAC is better than ABD as primary dressing after ankle replacement.
