HA versus grit blast tibial components in total knee replacement.
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.
