 note = {The purpose of the present study was to assess the clinical and radiographic results of primary cemented total hip arthroplasty with acetabular bone grafting. Twenty patients (21 hips) were included in the current study: two males and 18 females with a mean age at surgery of 54.5 years (range 40–66 years). The mean duration of follow-up was 12 years (range 8–15 years). The diagnosis for all hips at surgery was secondary osteoarthritis due to developmental dysplasia. The degree of subluxation as categorized according
to the classification of Crowe et al. was 11 hips in group I, 6 in group II, and 4 in group III. The Harris hip score was used for clinical evaluation. Standard anteroposterior radiographs were used for radiographic evaluation. The mean Harris hip score improved from 45.0 (range 24–60) before surgery to 90.4 (range 77–100) at the final follow-up. The mean proportion of the socket covered by the bone graft was 23.1%
(range 9.8–42.3%). At the final follow-up, three sockets showed radiological evidence of loosening. No revision surgery was undertaken during the investigation period since those patients had only mild pain and did not request surgery. Autogenous bulk structural bone grafting for reconstruction of the acetabulum yielded favorable results during a mean follow-up of 12 years, provided that the proportion of coverage
of the graft was less than 50%.},
