Multimodal Conservative Treatment of Complicated Open Wound After Total Knee Replacement Arthroplasty in Patients With Comorbidities.

Abstract

Total knee replacement arthroplasty is a common procedure and postoperative wound complications are sometimes inevitable. Although invasive reconstructive surgery may be an option for nonhealed wounds, such procedures can limit early rehabilitation, adversely affecting the range of joint motion. Patients can achieve a wider range of motion if they undergo early rehabilitation with a conservative approach. From 2015 to 2017, 5 patients with comorbidities who underwent total knee replacement arthroplasty were referred to the reconstructive surgery department for nonhealed open wounds. Depending on their comorbidities and conditions, the patients underwent negative-pressure wound therapy based on multimodal conservative treatment. During the treatment, the patients continued rehabilitation. In the 5 patients, the mean duration of complete wound healing was 65.2 days (range = 57-81), during which all open wounds were well healed. For final wound closure, the patients underwent skin grafting, dermatotraction, or collagen dressing. Four patients achieved ranges of joint motion over 100 degrees after treatment. We believe that early coverage is important for open wounds. For complicated open wounds after total knee replacement arthroplasty in patients with comorbidities, less invasive multimodal treatment along with early rehabilitation may be more effective to achieve adequate final range of joint motion.
