Zhang L, et al. - A medium-term follow-up study was performed to assess midterm clinical and radiographic results of total hip arthroplasty(THAs) with cementless implants for adult patients with sequelae from childhood hip infection. This study included a sum of 165 individuals (165 hips) who had a hip infection during childhood were treated with THAs with cementless implants between 2002 and 2016. In this study, 93.5 months (range, 26-206 months) was the average duration of follow-up. Harris hip score (HHS) assessed clinical outcomes and radiographic results were analyzed with postoperative serial x-rays. The results showed that cementless THA for adult individuals with sequelae from childhood hip infection shows significant technical challenges and a relatively high complication rate. The medium-term clinical and radiographic results of THA in this setting were good with high implant survivorship and patient satisfaction with meticulous surgical planning and anticipation for the key technical challenges frequently encountered.
