Medium term results of the collum femoris preserving hydroxyapatite coated total hip replacement.
We describe the survival of 75 collum femoris preserving (CFP) hydroxyapatite (HA) coated uncemented total hip replacement stems with a mean follow-up of 43 months (range 12-60). Patients were assessed using the Harris Hip Score. Radiographs were evaluated using Gruen zones and DeLee and Charnley zones. The criteria for failure were revision or impending revision. The mean Harris Hip Score was 50 preoperatively improving to 94 at final review, with 3 patients lost to follow-up. One cup was revised for aseptic loosening, whilst none of the stems required revision. Survivorship was 97% and 100% at 3 years for the cup and stem respectively. Our findings suggest that the medium term results of the CFP stem are excellent.
