Aim of the study is to compare clinical results and patient's satisfaction between direct anterior approach and Hardinge approach in primary total hip arthroplasty.
A group of 30 patients operated with DAA (group B) were compared to 39 patients operated by Hardinge approach (group A). Peri- and postoperative complications, Harris Hip Score (HHS), implant positioning, experienced pain and patient satisfaction were evaluated at a mean follow-up of 30 months.
HHS at follow-up was significantly better in group B (92.2 ± 11.9 vs 95.2 ± 4.5 p = 0.04 Student's t test). There was no difference in femoral stem positioning while cup inclination was significantly better in group B (40.6° ± 6.6° vs 44.3° ± 7.9°, p = 0.04 Student's t test). Overall pain recalled by patients was significantly lower in group B.
The introduction of DAA does not affect patients' final outcome but comes with comparable functional recovery and greater patient satisfaction.
