Perfusion Assessment of Wound Closure Techniques in Primary Total Knee Arthroplasty

This study will assess which of the three most common methods of wound closure in primary
total knee arthroplasty (staples, interrupted vertical mattress, or running subcuticular
suture) provide the best wound vascular perfusion. This can be achieve by using SPY
intra-operative vascular angiography, which is commonly used in clinical practice to assess
perfusion of wound closure at the clinic. By understanding the differences in perfusion
afforded by different closure techniques, surgeons will then be able to select the technique
that optimizes this parameter so as to avoid complications such as tissue necrosis, wound
dehiscence, or infection.
