The beneficial effect of hydroxyapatite lasts: a randomized radiostereometric trial comparing hydroxyapatite-coated, uncoated, and cemented tibial components for up to 16 years
Acta Orthop. 2012 Apr;83(2):135-41. doi: 10.3109/17453674.2012.665330. Epub 2012 Feb 13Exclusive Author Interview
Dr. B.G. Pijls speaks on the long term beneficial effect of hydroxyapatite in TKA.
48 patients (68 knees) scheduled for total knee arthroplasty were randomized to receive a cemented, cementless non-coated, or cementless hydroxyapatite (HA)-coated tibial component to determine the effect of HA on long-term migration of the prosthesis. Radiostereometric analyses (RSA), Knee Society Scores, Hospital for Special Surgery scores, and radiographic evaluation were recorded over 16 years. The results indicated that migration of HA-coated components was improved compared to non-coated components, but increased in comparison to cemented components.
