Computer-assisted total hip arthroplasty reduces early complications based on Japanese nationwide medical claims data.
Article in Archives of orthopaedic and trauma surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
introductionComputer-assisted (CA) surgery is increasingly adopted in total hip arthroplasty (THA) to enhance implant positioning accuracy. However, robust evidence regarding its impact on postoperative complications compared with manual THA (M-THA) remains limited. This study evaluated the association between CA-THA and early postoperative complications using a large Japanese database. MATERIALS AND
methodsWe analyzed 336,624 THA cases recorded in the Japanese Diagnosis Procedure Combination (DPC) database between December 2011 and March 2023. Of these, 242,067 underwent M-THA and 94,557 underwent CA-THA. One-to-one propensity score matching was performed to adjust for age, sex, body mass index, comorbidities, and diagnosis. Outcomes included surgical complications, medical complications, and in-hospital mortality.
resultsAfter matching, 93,887 patient pairs were analyzed. Compared with M-THA, CA-THA was associated with lower odds of dislocation (OR 0.667, 95% CI 0.556-0.786, p < 0.001), infection (OR 0.763, 95% CI 0.687-0.848, p < 0.001), and re-operation (OR 0.822, 95% CI 0.732-0.922, p < 0.001), but higher odds of periprosthetic fracture (OR 1.301, 95% CI 1.118-1.514, p < 0.001). No significant differences were found in medical complications or mortality.
conclusionsIn this nationwide cohort, CA-THA was associated with reduced risks of dislocation, infection, and reoperation, but an increased risk of periprosthetic fracture compared with M-THA. Further research should clarify optimal indications and refine patient selection criteria for CA-THA.
