Introduction[edit | edit source]

Negative-pressure wound therapy (NPWT) has been successful used in the wound management of various surgical arenas. NPWT is the application of below atmospheric pressure to the wound, aiming to reduce inflammatory exudate and encourage granulation tissue. It use is mainly used in complex wounds which are non-healing (eg surgical site infections (SSI's), wound dehiscence) or at risk of non-healing eg diabetics and the obese[1][2]. Due to the devastating consequences of infection following joint arthroplasty it has found a valuable use here. The pre-emptive use of NPWT after arthroplasty for those at high risk for postoperative wound drainage issues has the most robust clinical evidence. [3].

NPWT: use in surgical wound

High Risk Subset[edit | edit source]

The major risk factors include:

  • Obesity: negatively effects outcomes for those treated with TKA, with both increased short-term and long term complications. eg both SSIs and wound complications are associated with the TKA operations in the obese.
  • Diabetics
  • Tobacco Abuse
  • Malnutrition
  • Stress[4]
