A comparison of 127 HA coated with 70 grit blast titanium noncemented tibial components in TKRs has been carried out. Clinically the results were indistinguishable. Radiolucency was significantly less in the HA coated components suggesting improved fixation. At 5 years, loosening and wear have yet to be seen. These results suggest that HA may be a useful adjunct to noncemented component fixation in total knee replacement.
对127例全膝关节置换术中采用70目喷砂处理的非骨水泥型钛制胫骨假体并涂覆羟基磷灰石（HA）的情况进行了比较。临床结果无明显差异。HA涂层假体的透射线明显较少，提示固定效果改善。5年时，未见松动和磨损情况。这些结果表明，在全膝关节置换中，HA可能是增强非骨水泥型假体固定的一种有用辅助手段。
