The authors retrospectively analyzed 30 patients (involving 34 knees) who underwent revision arthroplasty of the knee using hinge or rotational knee prostheses and impaction bone grafting. The results: 25 patients were satisfied with their results. 10 patients reported no impairment in their activities of daily living attributed to their operation and did not need any walking support. In 5 patients, there were no clear radiographic signs of incorporation of the graft but that did not compromise the outcome. 5 other patients had complications due to the aseptic loosening of their prostheses with radiographic failure of the graft, leading to a periprosthetic fracture in 2 cases. Interpretation: The authors’ results with impaction bone grafting in knee revision arthroplasty appear to be similar to those obtained by the same technique in revision hip surgery.
