FIGURE 5

Post mortem assessment of implant osseointegration by bone histomorphometry: Coloured images show the typical nondecalcified histology examples of (a) metal implant; (b) biphasic calcium phosphate‐coated thermoplastic polyurethane (TPU) implant; and (c) uncoated TPU implant. Note that for (a) and (b) there is bone directly in contact with the implant whereas in C there is a persistent gap between the implant and the surrounding subchondral bone with fibrous encapsulation of the implant. Graph (d): Boxplot showing the histomorphometry analysis of osseointegration of the three different implants using the bone‐implant contact (BIC) percentage. TPU, BCP‐: Thermoplastic polyurethane implants without coating. TPU, BCP++: Thermoplastic polyurethane implants with biphasic calcium phosphate coating. Given values are the average of two observers (intraclass correlation coefficient is .851)
