Mid-term results for collum femoris preserving prosthesis comparable to cementless stems
Researchers concluded that the collum femoris preserving prosthesis could be comparable to cementless stems based on 11-year results presented in this study.
“In conclusion, the [collum femoris preserving] CFP prosthesis is a feasible treatment option in young patients with osteoarthritis of the hips,” Thorsten Gehrke, MD, and colleagues from the ENDO-Klinik in Hamburg, Germany, wrote in the study. “The current study demonstrates excellent mid-term results after 11 years, with a high survival rate for the stem and the acetabular cup. It suggests a promising future for this system, although it is not yet known if the results will be truly compared to cementless conventional stems.”

Gehrke and colleagues analyzed 149 total hip arthroplasty patients in their institution who received the CFP prosthesis between January 1999 and December 2000. They noted 117 patients were available for follow-up at mean 11.2 years.
Of the patients available for follow-up, 11 patients required revision, while 5 patients had implant-related complications, according to the abstract. Aseptic loosening occurred in 4 patients and led to implant removal.
