Clinical and Functional Outcomes of Knee Arthrodesis by Charnley's External Fixator.
Article in Cureus, 2024. 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
Background Knee arthrodesis was originally developed to manage severe joint infections such as tuberculosis before the advent of antibiotics and joint replacement techniques. The procedure aims to eliminate pain and infection by stabilizing the knee joint through bone fusion. Knee arthrodesis remains essential for cases where total knee arthroplasty is not feasible, such as in patients with severe bone loss, chronic infections, or failed knee replacements. Many studies have demonstrated fusion by external fixators because infection is the most common indication of this procedure. We studied knee arthrodesis using Charnley's compression clamps which are easy to apply and economical. Methodology A prospective observational study was conducted on 15 patients for 18 months. Patients with an infection in the knee joint (septic or tuberculous), failed total joint arthroplasty, failed fracture fixation around the knee joint, and neuropathic joints were included in the study. Patients were evaluated using the pre and postoperative Knee Society Score and Knee Society Score (Functional). Results In the study, 80% of the patients were males. Septic arthritis and tuberculosis were common indications for the surgery. More than 70% of the patients were previously operated on the same knee joint. The duration of the fixator ranged from 32 weeks to 39 weeks (7.47 months to 9.1 months) with an average of 35.73 weeks (8.34 months). The final follow-up period ranged from 9.5 to 18 months with an average of 14.1 months. The knee score ranged preoperatively from 5 to 22 (average = 16.2) and improved postoperatively ranging from 50-56 (average = 54). The functional score ranged preoperatively from 40 to 50 (average = 43.60) and improved postoperatively ranging from 80 to 100 (average = 89.66). Conclusions The fusion by Charnley's external clamps is easy, cost-effective, and comfortable for the patients. The complications are relatively fewer and the success rate of the fusion is higher with this treatment method.
