Superior fixation of pegged trabecular metal over screw-fixed pegged porous titanium fiber mesh: A randomized clinical RSA study on cementless tibial components
Acta Orthop. 2011 Apr;82(2):177-86.50 patients were randomized to receive either high-porosity trabecular metal (TM) tibial components or low-porosity titanium pegged porous fiber-metal (Ti) components in the treatment of primary osteoarthritis of the knee. This study was performed to compare the stability of these cementless implants. The results indicated that TM tibial components migrated less than the Ti components at 1 and 2 year post-surgery follow-ups.
