Research project: Finite element analysis of the proximal implanted tibia in relation to implant lossening

Currently Active: 

Aseptic loosening of the tibial component is the main cause of failure of knee implants. RSA can be used during the first two years after surgery to predict the risk of component loosening at five or more years.

Furthermore, it has been suggested that migration of the tibial component can be determined at the time of surgery. Tibial component alignment is one of the parameters that have most influence on implant loosening. The effect of varus-valgus and antero-posterior angles on the cancellous bone stress at the bone-implant interface was examined by means of finite element analysis. This study combined RSA migration data with FE analysis to explore this relationship between post-operative migration and initial mechanical conditions.
