Tibial and Femoral Components Migration and Adaptive Bone Remodeling After Insertion of Persona® TKA

Sponsor: Rigshospitalet, Denmark

Summary

The purpose of this study: In a prospective randomized study with 2 years of follow-up we want to compare the migration of the uncemented trabecular metal (TM) versus the cemented tibial and femoral components of the new Persona® total knee arthroplasty (TKA) assessed by model based radiostereometric analysis (MB-RSA). Also, we want to compare the adaptive bone remodeling induced by the uncemented TM versus the cemented tibial and femoral components of the new Persona® TKA assessed by dual energy-X-ray (DEXA). Data generated for both above mentioned, will be also compared with historical RSA and DEXA data for the NexGen TKA using TM tibia modular and monoblock.
