Purpose: The purpose of this study was to compare preoperative clinical outcomes before occurrence of periprosthetic femoral fracture (status before trauma) with postoperative clinical outcomes (status after operation) in patients with periprosthetic femoral fracture after hip arthroplasty.
Materials and Methods: A retrospective review was performed of all periprosthetic femoral fracture after hip arthroplasty treated surgically at our institution from January 2010 to January 2014. Among 29 patients who underwent surgical treatment for periprosthetic femoral fracture after hip arthroplasty, 3 patients excluded because of non-union of the fracture site. The clinical outcomes were determined by using visual analogue scale for pain (VAS), Harris hip score (HHS), and ambulatory ability using Koval classification. VAS, HHS and ambulatory ability was assessed for all the included patients at the last follow-up of status before trauma and after operation.
Results: The mean VAS, HHS and ambulatory ability at the last follow-up of status before trauma was 2.2 (range, 0-4), 78.9 (range, 48-92) and 1.9 (range, 1-5), respectively. The mean VAS, HHS and ambulatory ability at the last follow-up of status after operation was 3.1 (range, 1-5), 68.4 (range, 46-81) and 2.9 (range, 2-6), respectively. The clinical outcome of VAS, HHS and ambulatory ability were significantly worsened after surgical treatment for periprosthetic femoral fracture (P=0.010, P=0.001, and P=0.002, respectively).
Conclusion: Patients with periprosthetic femoral fracture after hip arthroplasty could not return to their status before trauma, although patients underwent appropriate surgical treatment and the fracture union achieved.
