Combined Anteversion Adjusted to Native Anatomy Improves Functional Outcomes in Total Hip Arthroplasty: A Retrospective Study of an Indian Sample Cohort.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: The alignment of the femoral with the acetabular components significantly influences the mechanics of the hip joint, especially in total hip arthroplasty (THA). Combined anteversion (CA) is a combination of femoral neck anteversion and acetabular anteversion (AA). CA is emerging as a significant factor that influences optimal THA outcomes. Our study aims to assess the impact of CA on postoperative functional outcomes in an Indian cohort where unique lifestyle demands may influence the anteversion characteristics. Materials and Methods: A retrospective study was conducted on 88 patients undergoing THA. Inclusion criteria included patients with unilateral THA due to femoral neck fractures or osteonecrosis of the femoral head. Computed tomography scans were used to identify and measure postoperative CA. We assessed the functional outcomes following THA at 7 days, 6 weeks, 3 months, 6 months, and 1 year, using the Harris hip score (HHS). Results: Our findings indicate that the CA values ranged from 25.5° to 93.9°, with a mean of 59.3°±15.7°. Patients with CA between 40° and 70° exhibited significantly improved functional outcomes, with an improvement in the mean HHS from 67.57 at day 7, to 94.26 at 3 months, to 97.50 at 1 year ( Conclusion: Our study concludes that achieving a CA within the range of 40° to 70° is pivotal for optimal functional outcomes and for minimum complications in THA.
