Staples or Sutures

Wound complications are one of the major contributors of morbidity after orthopaedic surgery and can prolong inpatient stay or lead to re-admission. Both staples and sutures are used for wound closure after Total Hip Arthroplasty (THA).  Outcomes in terms of wound infection, inflammation, discharge, dehiscence and necrosis are comparable, but they are based on underpowered studies with poor methodological quality. In the Netherlands, approximately 21.000 THA’s are performed and this number is expected to grow. It is time to optimize this procedure.
The objective is to compare staples versus sutures for wound closure after Total Hip Arthroplasty
Study design
Randomized Controlled Trial
Study population
Patients over 18 years who will undergo Total Hip Arthroplasty
Main study parameters/endpoints
The main study parameter is the difference in superficial wound infections between the two groups. Other parameters are deep wound infections, wound necrosis, wound dehiscence, wound discharge and length of hospital stay. Assessment will take place during hospital stay.  Follow-up will occur at regular visits in the outpatient clinic for removal of staples or sutures after 14 days, after 4-6 weeks, 3 months and 1 year.
