surgical techniques1,2). However, the increase in the employment of the procedure has led to a greater need for revision TKA3). Advanced implant design and surgical techniques have also enabled revision TKA to yield more promising results. Still, revision TKA is less satisfactory than primary TKA in many cases with reported success rates of 30-89%. In addition, revision procedures are technically more demanding because of the bone loss during implant removal, instability, skin and soft tissue vulnerability, and infection2,4-6). The causes of revision TKA can be largely divided into infectious and non-infectious. Non-infectious causes are often related to component loosening, wear, instability, malalignment, and periprosthetic fractures. The results of revision TKA for non-infectious reasons were less satisfactory than those of primary TKA in some studies4,7), whereas comparable to the primary surgery according to the study by Insall and Dethmers8). The incidence of deep infection following TKA has been decreasing due to the development of prophylactic antibiotics and thorough infection control, but infection is still known as one of the most common causes of revision9).
