title: Midterm results of uncemented acetabular reconstruction for posttraumatic arthritis secondary to acetabular fracture.
abstract: At an average of 6.3 years after surgery, we evaluated midterm results of uncemented acetabular reconstruction in 31 hips with posttraumatic arthritis that developed after acetabular fracture. Patients were categorized by previous fracture treatments (open-reduction group and conservative-treatment group) and fracture patterns (simple group and complex group). Surgery duration and blood loss were greater in the open-reduction and complex groups than in the conservative-treatment and simple groups (P < .05). The mean Harris Hip Score increased from 49 before surgery to 89 after surgery. Survival with revision or radiographic acetabular loosening as an end point was 100%. Fracture treatments and patterns were associated with increased surgery duration and increased blood loss. Open reduction and internal fixation of a fracture favor anatomical restoration of the hip's rotational center.
