Primary THA using 3rd generation Ceramic on Ceramic articulation

초록

A ceramic is currently considered as the most ideal articulation in primary THA. The authors evaluated clinicoradiographic results and complications of cementless THA with 3rd generation of ceramic bearing. From April 2001 to January 2008, 310 primary THAs were performed in 300 patients using 3rd generation of ceramic bearing. In results, Harris hip score at last follow up was improved to an average of 95.4 points from 51.6 points preoperatively. In all cases, fixations around implants were stable and there was no osteolysis. Complications were dislocations, squeaking, ceramic femoral head and liner fracture. Our outcomes using cementless THA with 3rd generation of ceramic articulation were satisfactory, but more clinical study and investigation will be necessary to reduce complications.
