D and E General view after the screw is implanted into the distal femur. F Residue of PVA coating in the bone marrow cavity. G Plate coating 2 weeks after the operation (bar = 10 mm). H Crystal violet staining of the implant. I and J Quantitative results of colony formation around the implant. K and L Quantitative results of crystal violet staining on the implant Data are represented as means ± SD. Significant differences are indicated as **(p < 0.05)
