Incisional squamous cell carcinoma after total knee arthroplasty

With the rising number of total knee arthroplasties being performed annually, the number of complications associated with this procedure will also continue to rise. The most common reasons for revision include infection, instability, and aseptic loosening. Fortunately, wound complications are rare, and in this case report, we describe the development of a well-differentiated squamous cell carcinoma, keratoacanthomatous type, within the surgical incision of a total knee arthroplasty several months after the index procedure.
