Abstract:
Objective:To evaluate the long-term clinical outcomes of total hip arthroplasty with the 4th ceramic-on-ceramic bearing in patients with history of hip injury.Methods:During December 2008 to December 2011, a total of 153 patients (157 hips) with history of hip injury were treated with 4th ceramic-on-ceramic bearing total hip arthroplasty. There were 25 cases (25 hips) were not followed up (16.3%). Ultimately, a total of 128 cases (132 hips) aged 49.26±14.18 (range 17-76) years including 87 males and 41 females were included in the study. In these patients, there were 15 cases (11.4%) with acetabular fracture, 90 cases (68.2%) with femoral fracture, 5 cases (3.8%) with hip dislocation and 22 cases (16.7%) with unknown history. Clinical outcomes, including operation duration, Harris score, range of motion, complications and noises, were evaluated. The survivorship was investigated by using Kaplan-Meier method.Results:The operation duration was 135.61±41.65 (range 64-320) min. The average follow-up duration was 9.62±0.82 (range 8.2-11.3) years. The Harris score increased from preoperative 44.07±19.71 to 94.03±4.10 at the last follow-up ( t=24.155, P<0.001). The range of hip motion increased from 75.90±28.05 degrees to 117.14±12.36 degrees ( t=13.176, P<0.001). There was no significant difference in Harris scores and ranges of motion among the groups with different history of fracture and dislocation. There were periprosthetic fracture in 1 case and hip dislocation in 2 cases. There was no periprosthetic hip infection or fracture of ceramic liner during the follow up. Thirteen cases (13 hips, 9.8%), including squeaking in 9 cases (6.8%) and clicking in 4 cases (3.0%), reported hip noise without pain and impairment on the quality of life. The survivorship was 100% at 10 years when regarded revision as an end point. However, the survivorship was 99.24% (95% CI: 97.8%, 100%) at 10 years when reoperation revision as an end point. Conclusion:Total hip arthroplasty with 4th ceramic-on-ceramic bearing could have excellent results for patients with a history of hip fracture or dislocation in the long-term follow-up. Although the prevalence of hip noise was about 10% in this cohort study, there was no impairment on the quality of life.
