Abstract
Aseptic loosening of the tibial component is the main cause of failure after total knee arthroplasty and is related to micromovements. Therefore a good fixation of the tibial component to the proximal tibia is essential; this could be achieved by increasing the cement penetration depth. We investigated two variations of the surface cement technique using five fresh frozen cadavers (n=5) comparing these techniques in both sides. Our primary outcome was cement penetration in the proximal tibia (in mm). The application of the prosthesis was performed in the same way as in the operation room, influencing factors were standardized. Afterwards cross sections of the proximal tibia were analysed and the size of the cement mantle was assessed. We found that when cement is applied only on the tibial component, cement penetration is significantly less than when cement is applied on both the tibial component and the tibial plateau. In this way the optimal cement penetration of 3-5 mm is reached, when cement is applied on the tibial component only, cement penetration is insufficient.
