Analysis of the Functional Outcome of Surgically Operated Floating Knee Injury.
Article in Cureus, 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
Background and objective A simultaneous ipsilateral femur and tibia fracture that separates the knee from the rest of the limb is known as a "floating knee." Both extra-articular and intra-articular fractures are included. The aim of this study is to analyze the functional outcome in surgically operated floating knee injuries. Methods The prospective study was conducted with 20 patients with floating knee injuries who were operated on at the Adichunchanagiri Institute of Medical Sciences. These fractures are classified by using the modified Fraser's classification. Patients were followed up for a minimum of six months. The clinical and functional outcome of these patients was assessed by using the Karlström and Olerud criteria. Results The mean age of the patients was 34.50±13.48 years. The mechanism of injury was road traffic accidents (RTA) in 19 patients and a fall from height in one patient. Based on Fraser's classification, 11 had Type I fracture, two had Type IIA fracture, one had Type IIB fracture, and six had Type IIC fracture (p=0.34). Based on treatment, three patients with femur fractures were treated with cannulated cancellous (CC) screws. According to the Karlström and Olerud criteria, the outcome was acceptable in four patients (20%), excellent in seven patients (35%), good in six patients (30%), and poor in three patients (15%). According to Fraser's classification, seven patients with Type I fractures (63.6%) had excellent outcomes. Conclusion Long-term rehabilitation and careful surgical planning are advised for the fixation of the fractures. The final result for these individuals is determined by a combination of these factors.
