Product Overview
-The Evolution® medial-pivot knee system with
BioFoam® cancellous titanium on the tibial implant is
the next generation in cementless fixation. Alongside
the medial-pivot knee system’s clinically
demonstrated design, built on the latest kinematic
evidence of the natural stability and motion of the
knee, BioFoam® cancellous titanium is uniquely suited
to meet the challenges of today’s patient population.1
By offering surgeons unparalleled biologic fixation and
fixation, this novel material provides a true trabecular
structure with enhanced rigid fixation to allow
immediate fixation through an osteoconductive
matrix.
Clinical success of BioFoam® fixation
-Initial and short-term fixation of cementless tibial
implant is critical to early patient satisfaction and
long-term biologic ingrowth. A recent 2015 study by
Waddell et al demonstrated strong evidence early
radiographic and functional outcomes.2
Study highlights
-104 TKA’s performed in 85 subjects by four surgeons
-Subjects were evaluated preoperatively, and at 6, 12,
and 24 months postoperatively
-KSS scores and maximum flexion were significantly
improved at 12 and 24 months
-No progressive radiolucencies
-Only 1 patient presented with a radiolucency around
the tibial component
BioFoam® features:
True trabecular architecture
-The structure of BioFoam® cancellous titanium acts
as a biological scaffold designed to allow fast, fluid
bone ingrowth. Osteoblasts are able to cling to the
course titanium struts; conducting angiogenesis
through the interconnecting pores.3
Compressive strength
-The structure of BioFoam® cancellous titanium
resembles that of trabecular bone. The pore cell size
averages 530μm and the diameter of interconnecting
pores averages 200μm.4
-Roughened to enhance immediate fixation
-High coefficient of friction5
