PURPOSE: This study is a long-term review of an hydroxyapatite (HA)-coated knee prosthesis. Our aim was to confirm that excellent previously reported results with HA knees could stand the test of time at the 15-year milestone. METHODS: A total of 270 cruciate retaining HA-Omnifit knees, implanted in the same institution by a single surgeon with the same surgical procedure, were reviewed at 15-22 years of clinical follow-up (75 knees partially-coated and 195 fully-coated). RESULTS: At review, IKS mean values were 95.6 points for knee score and 91.19 points for function score. Radiological review confirmed an excellent long-lasting fixation over years in the long run. Taking implant failure as the end-point, the survival rate was 97.1% at 20 years. CONCLUSIONS: Our results were as good, and often better, than the best cemented or porous published studies. These very encouraging results at 15-22 years make us very confident in the ultimate outcome of bioconductive coatings in knee arthroplasty.
