Radiologic assessment of postoperative pelvic radiographs for acetabular implants and preoperative versus planned leg length for patients who underwent the posterior or direct anterior approach for total hip arthroplasty
| Variable | Approach | p value | |
|---|---|---|---|
| PA n = 27 | DAA n = 28 | ||
| Implant | |||
| Cup anteversion, degrees, mean ± SD | 21.9 ± 13.4 | 26.9 ± 8.6 | 0.10 |
| Cup abduction, degrees, mean ± SD | 39.8 ± 5.4 | 43.3 ± 8.4 | 0.06 |
| Preoperative LLI, mm, mean ± SD | −2.4 ± 4.3 | −2.2 ± 4.8 | 0.87 |
| Planned leg length discrepancy, mm, mean ± SD | 1.0 ± 5.6 | −2.2 ± 6.8 | 0.06 |
DAA = direct anterior approach; LLI = lower leg inequality; PA = posterior approach, SD = standard deviation.
