Minimum One-Year Outcomes after Revision Hip Arthroplasty with Custome-Made Implants: Function, Quality of Life and Patients Satisfaction

Abstract

Purposes of our study were to estimate clinical short-term results of custom acetabular implants using in revision hip arthroplasty, to determine bone ingrowth percentage in the custom implant 3d printed coverage, and to estimate the custom malposition influence on the clinical results.Materials and method. 30 patients were performed revision hip arthroplasty with using custom acetabular implants in 2016. Oxford hip score, life quality, expectation and satisfaction of patients were assessed in 12 months and more. Osteointegration was assessed with x-ray. Influence of malposition on clinical results was assessed with Pirson’s χ2.Results. Oxford Hip Scores were increased from mean 16.8 to 34.4 (p<0.01). Life quality index EO-5D were increased from mean 0.315 to 0.651 (p<0.01). Osteointegration was confirmed in 96% cases, component migration was in 1 case. The influence of malposition on clinical results in short-term follow-up was absent.Conclusion. The using of custom acetabular implants in revision hip arthroplasty improves hip function and life quality of patient. 3D printed custom implants coverage provides high percentage of inplants osteointegration, besides components malposiotion. Further followup requires for assessment long-term results.
