Introduction[edit | edit source]

NPWT: use in surgical wound

Negative-pressure wound therapy (NPWT) has been successful used in the wound management of various surgical procedures. 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 those at risk of non-healing eg diabetics and the obese[1][2].

Use in Total Knee and Total Hip Arthroplasty[edit | edit source]

Due to the calamitous 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]. Current research supports the application of NPWT to reduce the incidence of wound complication and SSI in:

  • High‐risk patients after THA or TKR
  • Revision procedures after THA or TKA[4]

High Risk Group[edit | edit source]

The major risk factors for wound management problematic issues 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
  • Older Persons
  • Stress[5]
