1 · What the graph read from it

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.

2 · The registry

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

Introduction: Treatment of advanced knee osteoarthritis (OA) with periarticular fractures is challenging, particularly when accompanied by non-union of patellar fractures. In the elderly, multiple surgeries pose disadvantages because they increase the anesthetic risk and the incidence of perioperative complications and prolong the time required for functional recovery. We report a case of advanced knee OA with non-union of a patellar fracture after open reduction and internal fixation (ORIF) that was treated with one-stage total knee arthroplasty (TKA) together with bone grafting. Case Report: An 85-year-old female with advanced OA of the left knee presented with the treatment of non-union of a left patellar fracture following ORIF. Conservative treatment using low-intensity pulsed ultrasound and teriparatide for 1 year proved ineffective, prompting us to perform simultaneous TKA and ORIF of the patellar non-union. One year postoperatively, the patient achieved a favorable outcome. Conclusion: We performed simultaneous left TKA and ORIF with bone grafting in a patient with knee OA and non-union of a patellar fracture. This procedure allowed the bone resected during TKA to be used for bone grafting at the pseudarthrosis site.
