Histologic findings at 14 and 18 years after cemented total hip arthroplasty with interface bioactive bone cement technique.
To augment cement-bone bonding in total hip arthroplasty, we interposed hydroxyapatite (HA) granules at the interface. We report the histologic findings of 2 cases 14 and 18 years after cemented total hip arthroplasty with this technique. We found that a thick bony layer was observed where rich layers of HA granules existed. In areas without HA granules, the trabeculae did not form a thick bony layer. These bony layers around HA granules were observed at the interface of non-weight-bearing and weight-bearing areas in 2 acetabula after long-term follow-up.
