Knee Arthropathy Clinical Trial
Official title:
Routine Use of Negative Pressure Wound Therapy in Primary Hip and Knee Arthroplasties; a Randomized Controlled Trial
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.

Primary | Wound-related complications | Recurrence of wound exudate, surgical site infections, dressing-related issues, readmission to hospital and any further surgical interventions will be documented by the research personnel status at 21 days after the index operation. | 21 days after surgery | |
Secondary | Patient Scale and Observer Scale (POSAS) | The POSAS has category boxes to core nominal parameters, for example colour of the scar. Each item of both scales have a 10-point score, with 10 indicating the worse imaginable scar or sensation and 1 corresponding to normal scar or skin (normal pigmentation, no itching, etc.). The total score of both scale is calculated by summing up the score of each of the six items and ranges from 6 to 60. | 21 days after surgery | |
Secondary | Multi-category visual analogue scale | The multi-category visual analogue scale (VAS) is a photograph based scale derived from evaluating standardised digital photographs in four categories (pigmentation, vascularity, acceptability and patient comfort) plus contour. The individual scores are added to give a single overall score ranging from "excellent" to "poor" | 21 days after surgery |
