对19例知情同意的双侧全膝关节置换术（TKA）患者进行了人体松质骨长入研究。在TKA时（6-131周后），将钛多孔涂层圆柱体植入对侧膝关节的内侧股骨髁，并进行荧光染料分析。平均矿物质沉积率（MAR）在接口处测量1.0亩/天，而4毫米远，外周骨的平均MAR为0.8亩/天。这表明与外周相比，界面骨重建速率加快了25%（P
Human cancellous bone ingrowth studies were conducted on 19 consenting bilateral total knee arthroplasty (TKA) patients. Titanium porous coated cylinders were implanted into the medial femoral condyle of the contralateral knee during of two the Retrieval was performed at the TKA (6-131 weeks later), and fluorochrome analysis was conducted. Mean mineral apposition rates (MAR) at the interface measured 1.0 mu/day, whereas 4 mm away, the peripheral bone had a mean MAR of 0.8 mu m/day. This represented a 25% acceleration in the interface bone remodeling rate when compared with the periphery (P
