This prospective single-surgeon series followed young TKA patients (under 60 years) who received an uncemented porous tantalum monoblock tibial component. It reports clinical, radiographic, and functional outcomes at a mean of 10 years. The question: can biologic tibial fixation match cemented durability in a high-demand young population?
Cemented tibial fixation is the standard in TKA, backed by 94% survival at 25 years. The concern in young patients is bone stock loss and easier future revision, which biologic ingrowth may address.
This paper answers whether a porous tantalum monoblock tibia can deliver durable fixation in patients under 60. At mean 10 years, there were zero cases of tibial loosening and a 6% all-cause revision rate driven entirely by non-tibial causes.
A key teaching point: the authors credit the low osteolysis to the monoblock design (less backside wear), not cementless fixation itself. Cementless fixation is not a better barrier to wear particles. Weigh the evidence appropriately. This is Level IV, single-surgeon, single-implant data with 17% lost to follow-up. It supports, but does not yet prove superiority over, cemented fixation.
