What are the scars like after a knee arthroplasty?

Anterior & vertical: The typical knee arthroplasty scar is anterior and runs in line with the lower extremity. It appears longer when the knee is flexed than when it is extended. It is longer in larger or more obese individuals. It is wider in keloid formers. Most surgeons minimize the length of their incisions to prevent unnecessary damage to adjacent structures, but will lengthen it if they are unable to see well.

5-10 inches: The incision is made vertically over the kneecap. We use a minimally invasive technique that results in a smaller scar.
