Abstract

The results of 18 matched pairs of Porous Coated Anatomic knee prostheses were studied to compare the early clinical and functional performance of cemented versus uncemented fixation with an average five-year follow-up period for both. The knee score improved from a preoperative average of 35 points to a postoperative average of 90 points in the cemented group, and from 38 points to 93 points in the uncemented group. In particular, the individual pain scores and the range-of-motion values were well matched at the three-, six-, and 12-month follow-up visits and showed a steady improvement. Subjectively, all patients were pleased with the results of surgery; one-third preferred the cemented side, one-third preferred the uncemented side, and one-third found no difference in the performance of either knee. The clinical and functional performance of knee prostheses in patients who had one cemented knee and one uncemented knee were comparable and possibly unrelated to the type of fixation method.
