Effect of femoral prosthesis flexion angle on unicompartmental knee arthroplasty with mobile platform.
Article in Journal of orthopaedic surgery and research, 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
objectiveTo investigate the effect of the flexion angle of a femoral prosthesis on the postoperative clinical outcome of patients with knee osteoarthritis who are undergoing unicompartmental knee arthroplasty.
methodsPatients were divided into three groups according to the flexion angle of the femoral prosthesis following unicompartmental knee arthroplasty. Group A comprised patients with a flexion angle of the femur prosthesis of less than 5°, Group B included those with a flexion angle of 5° to 10°, and Group C consisted of patients with a flexion angle of the femur prosthesis greater than 10°. The basic clinical data, visual analog scale (VAS) score, Hospital for Special Surgery (HSS) score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score and knee range of motion (ROM) were subjected to statistical analysis and comparison between the groups.
resultsNo significant differences were observed in the basic data of the patients in each group. The ROM and VAS scores for the knee in the first month following unicompartmental knee arthroplasty in groups B and C were significantly greater than those in group A. The HSS scores for the knee joint in Group B indicated superior outcomes in the initial postoperative month and the third postoperative month, as evidenced by the WOMAC scores, which demonstrated a statistically significant difference between Group B and the other two groups within the six-month postoperative period.
conclusionThe short-term recovery of patients in Group B was the fastest. These results provide a new reference for the installation of femoral prostheses in unicompartmental knee arthroplasty.
