Background: Acetabular fractures are common traumatic injuries globally, posing challenges owing to their complex nature and difficulties in achieving precise anatomical reduction. Total hip arthroplasty (THA) is a valuable treatment for posttraumatic osteoarthritis secondary to these fractures; however, outcomes can vary based on initial fracture management, and optimal strategies remain debatable.
Objectives: This study evaluates THA outcomes in patients with previous acetabular fractures managed with open reduction and internal fixation (ORIF).
Methods: We conducted a retrospective review of patients who underwent THA for posttraumatic osteoarthritis following acetabular fractures managed with ORIF. The inclusion criteria comprised osteoarthritis graded ≥III according to the Kellgren-Lawrence classification and a minimum two-year follow-up. Clinical outcomes were assessed using the Harris hip score (HHS).
Results: Sixty-eight patients who underwent THA after ORIF for acetabular fractures were included (mean age 52.5±13.8 years). Preoperative HHS improved significantly from 41.4±9.9 to 83.1±10.4 at the final follow-up (P<0.001). Postoperative complications occurred in 54.4%, with 11.8% requiring revision THA.
Conclusion: THA for posttraumatic osteoarthritis following acetabular fractures, particularly in patients managed with ORIF, shows significant clinical improvement but has a high complication rate.
