简要总结
Negative pressure wound therapy (NPWT) for post total joint arthroplasty incisions has demonstrated benefits in reducing wound complications. A prospective randomized trial will be conducted including 40 patients who will undergo total knee and total hip arthroplasty. The number of wound complications within 21 days will be recorded. As well, the aesthetic appearance and quality of scarring of the scar will be assessed.

入选标准
- •Patients undergoing total knee or total hip arthroplasty at Prince of Wales Hospital, Hong Kong.

研究组 & 干预措施
negative pressure wound therapy
Both groups will have layered closure with 2-O Vicryl (polyglactin 910) braided suture for the subcutaneous layers and 3-O Stratafix knotless barbed suture for the subcuticular layer. Fixation strips (STERI-Strip, 3M) would then be applied to the entire length of the wound. For the NPWT group, the Smith & Nephew PICO dressing will be chosen as it is versatile with various size options, and the small suction pump is would not causing much problems to patient mobility. For the standard dressing group, the same PICO dressing will be applied, but without the suction.
