With the TUREMOS-Prosthesis system we will present a new constraint titanium hydroxi-apatit covered prosthesis with a new reliable anchoring system due to its full-surface contact metal to bone that is implanted cementless since May 1996 by one surgeon.

Material and Method

In a prospectiv study we followed 54 patient, 34 women and 20 men, who were operated at the age of 22 to 88, average 59 years, in 18 cases due to primary bone tumors, in 8 cases due to secondary bone tumors and in 28 cases due to failed knee-prosthesis. Follow up was at least 12 month, 12 to 80 months, mean 46 months. All patient were personally controlled by the authors.


In 41 cases we found a very good result with patients in a fully rehabiltiated situation walking without cane and following their daily work and living. 6 patients need one cane and in 7 cases patients had to walk with 2 crutches or needed a wheel-chair, in all these seven cases due to other medical reasons. In three cases we found a loosening of the femoral component, two needed resurgery, one could be controlled conservatively. One patient needed amputation due to uncontrollable infection. We found in all cases, also after resurgery or conservative treatment of loosened femoral componend, a radologically completely femoral and tibial bony integrated prosthesis.

We will show the homogeneous, all-surface, osteointegration of the anchoring system with histological review of two prosthesis components.
