The Importance of Different Modularity of the Polyethylene Insert for Tibial Component Migration and Adaptive Bone Remodeling After Uncemented Total Knee Arthroplasty Using Trabecular Metal Technology (TMT) Zimmer NexGen®, (Monoblock vs. Modular Design)
In a prospective randomised study two uncemented tibial components with different polyethylene modularities (Trabecular Metal Technology (TMT) Zimmer NexGen® monobloc and TMT Zimmer NexGen® modular) used for total knee arthroplasty (TKA) is evaluated. Both tibial component coatings are designed to provide excellent condition for bone ingrowth.
The differences between the two tibial components are evaluated by measurements of migration of the tibial component assessed by Radiostereometric analysis (RSA) and measurements of the adaptive bone remodeling of the proximal tibial assessed by dual energy X-ray absorptiometry (DEXA).
