[Comparison of Capsular Closure and Capsulectomy in Primary Total Hip Arthroplasty Using the Direct Anterior Approach].
Article in Revista brasileira de ortopedia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: To compare the clinical, radiographic, and complication outcomes of patients undergoing capsular repair or resection during total hip arthroplasty (THA) using the anterior approach. Methods: The present prospective cohort study included 232 patients submitted to THA at a tertiary hospital, who were divided according to exposure. One group of subjects underwent THA with capsular preservation and closure, and the other underwent THA with capsular resection (capsulectomy). Clinical assessment included the Harris Hip Score (HHS), evaluation of hip range of motion, and identification of symptoms indicative of iliopsoas tendinitis. Additionally, a radiological assessment determined the presence of heterotopic ossification, and we evaluated any postoperative complications. Results: There was no statistically significant difference in HHS and hip range of motion. No patient from the capsular closure group presented complications. In the capsulectomy group, 7 (5.20%) subjects presented with heterotopic ossification, including 1 case classified as Brooker grade 3, besides 3 (2.25%) cases of iliopsoas tendinitis and 1 (0.75%) case of prosthesis dislocation. Conclusion: Capsular closure in THA using the direct anterior approach resulted in a lower incidence of iliopsoas tendinitis, heterotopic ossification, and complications, such as prosthesis dislocation, compared with the capsulectomy group.
