In Chapter 6 the radiographic long-term result of the SKI prosthesis is described. The presence, increase and patterns of radiolucency around the three components were analyzed on two consecutive, comparable radiographs. To correlate the radiographic result with the clinical performance, the radiolucency around prostheses with clinical signs of loosening and without clinical signs of loosening was studied separately.
In the group of prostheses without clinical signs of loosening, the factors that might contribute to the presence and increase of radiolucent lines were analyzed. Additionally, the correlation between radiolucency and osteophytes around the patellar component and the presence of anterior knee pain was studied.
