Purpose: To assess the clinical and radiographic results of 24 total hip arthroplasties performed in hip ankylosis.
Materials and Methods: We evaluated 24 total hip arthroplasties performed in 21 patients with bony or fibrous ankylosis of hip joints. The age distribution was from 23 to 71 years with an average age of 46 years. Average period of ankylosis was 21 years (2~ 41 years), in which 14 cases were bony ankylosis (58.3%). The mean follow-up period was 62 months
Results: Overall Harris Hip Score improved from 57.5±8.7 preoperatively to 78.8±6.1 postoperatively. There was no significant difference in Harris Hip Score between bony and fibrous ankylosis groups, however fibrous ankylosis group showed better results in the range of motion and improvement of limp than bony ankylosis group(p<0.05). The radiographic findings showed no femoral stem loosening. In one case, complete wear of acetabular polyethylene liner developed and the acetabular cup migration developed in one other case. In both cases, acetabular cup revision arthroplasty was peformed.
Conclusion: The conversion total hip arthroplasty in ankylosed hips revealed a relatively favorable outcome. In the bony ankylosis, careful selection of patients and meticulous operative technique should be realized for more satisfactory results.
