To determine whether cemented fixation is associated with early postoperative complications compared with uncemented fixation in elective total hip arthroplasty (THA) for osteoarthritis, osteonecrosis, or rheumatoid arthritis in Japan.
Key Findings:
Cemented fixation was associated with lower rates of postoperative dislocation, surgical site infection, and other complications compared to uncemented fixation, with statistically significant differences.
Interpretation:
Cemented femoral fixation may provide better early postoperative outcomes in THA, suggesting a reevaluation of fixation preferences in Japan is warranted.
Limitations:
The study is based on administrative data, which may include coding inaccuracies.
The analysis is limited to patients aged ≥ 65 years, which may not represent outcomes in younger populations, potentially affecting the generalizability of the findings.
Conclusion:
Cemented fixation in total hip arthroplasty is associated with lower early complication rates, suggesting a need for reevaluation of fixation preferences in Japan.
