Three-compartment knee prosthesis Evolution®BIOFOAM®

The Evolution® medial-pivot knee system is designed to answer the limitations of traditional implants by delivering superior flexion stability, anatomic motion, and wear–limiting design characteristics. 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. 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
