Association of postoperative acetabular abduction angle with gait asymmetry and adverse reactions following total hip arthroplasty across different surgical approaches

Key Points

This study aims to explore the relationship between surgical approach, acetabular abduction angle, and their effects on gait symmetry and complications following total hip arthroplasty.
Sixty patients were grouped by surgical approach and acetabular abduction angle (ideal 40°-50°, non-ideal <40° or >50°).
Postoperative assessments included gait asymmetry index, acetabular anteversion, hip center displacement, and serum inflammatory markers.
Adverse events were recorded within a 12-month follow-up period.
Patients with an acetabular abduction angle of 40°-50° showed reduced gait asymmetry (p<0.05).
The direct anterior approach correlated with lower complication rates after total hip arthroplasty (p<0.05).
Improved early recovery was noted in patients aligned within the ideal acetabular angle.

Abstract

BACKGROUND: Total hip arthroplasty (THA) is effective for end-stage hip disorders, but evidence on the combined effects of surgical approach and acetabular abduction angle remains limited. This study investigated the associations of surgical approach and acetabular abduction angle with gait symmetry, prosthesis alignment, and complications after THA. RESEARCH DESIGN AND METHODS: = 60 each). Each group was further stratified by acetabular abduction angle (ideal 40°-50°; non-ideal: 50°). Gait asymmetry index (AI), acetabular anteversion, hip center displacement, and serum inflammatory marker levels were assessed postoperatively. Adverse events within 12 months were recorded. RESULTS: < 0.05). CONCLUSION: The direct anterior approach and an acetabular abduction angle of 40°-50° were associated with improved early recovery, reduced gait asymmetry, and lower complication rates after THA.
