Eleven-year results of the anatomic coated CFP stem in primary total hip arthroplasty.

There is a paucity of intermediate term results relating to short stem prostheses. The current study represents the longest follow-up results of the CFP prosthesis to the authors' best knowledge. Between January 1999 and December 2000, all total hip arthroplasty patients (n = 149), treated with this anatomic neck preserving stem in the authors' institution were enrolled in this study. After a mean follow-up time period of 11.2 years 117 patients were available for the follow-up examination. The mean HHS increased from 53 to 93. Overall, revision surgery was required in 11 patients (9.4%), with implant-associated complications noted in only five cases (4.3%). Aseptic loosening leading to implant removal was noted in four patients (3.4%). The current study's data suggest that the CFP implant, used in young patients undergoing primary total hip arthroplasty, is safe and provides excellent results after 11 years.
