The use of Trabecular Metal (TM), a biomaterial manufactured from elemental tantalum metal, has recently increased in orthopedics. One hundred eight consecutive TM monoblock tibias were implanted in 95 patients and followed for a minimum of 2 years. The average follow-up was 4.5 years. The average age was 65 years. The Knee Society score of 36 improved to 89. One hundred five of the knees were rated good/excellent, and 3 knees were rated poor. Two patellar revisions were performed for loose components and one for patellar misalignment. One patella fracture required open reduction and internal fixation. One femur was revised. There were no tibia revisions. There were no progressive radiographic lucencies. Midterm clinical and radiographic results of 108 consecutive TM tibia components have a high rate of success.
