Product Details
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.
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
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
