The use of negative-pressure wound therapy after total knee arthroplasty is effective for reducing complications and the need for reintervention.

The number of complications related to the wound after TKA is high; however, most of them are minor and have no impact on the treatment and clinical evolution of patients. The use of NPWT decreased the number of surgical wound complications, especially hyperaemia, dehiscence and necrosis, and reduced the need for reintervention.
