The influence of joint line restoration on functional outcome after primary total knee arthroplasty: A prospective study.
Article in Journal of clinical orthopaedics and trauma, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 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
Objective: Restoration of proper joint line position after primary total knee arthroplasty (TKA) is important for improved knee function and kinematics. We reviewed the magnitude of joint line alteration and the resulting effect on post-operative knee outcomes scores at one year follow-up. Materials and methods: 120 patients who underwent TKA for primary osteoarthritis knee were included. Assessment of joint line position before and after surgery was performed with the help of bony landmarks (excluding osteophytes): Medial Epicondyle Joint Line distance (MEJL), Lateral Epicondyle Joint Line distance (LEJL) and Fibula Head Joint Line distance (FHJL) were calculated. Post-operative knee function was assessed using 'The Western Ontario and McMaster Universities Arthritis Index' (WOMAC) and 'Knee Society Score' (KSS) at one year follow-up. Results: Joint line elevation was observed in 104/120 (86.7%) patients and 16/120 (13.3%) patients had no joint line elevation. The mean joint line elevation was 3.00 (±2.13) mm. The patients were sub-classified into two study groups: Group A- Joint line elevation <5 mm and Group B- Joint line elevation ≥ 5 mm. The mean post-op one-year KSS score was significantly higher in patients in Group A compared to Group B (52.82 ± 7.564 vs. 40.73 ± 7.146; p < 0.001). The mean post-op one-year WOMAC score was lower in patients in Group A compared to Group B (65.51 ± 14.762 vs.75.64 ± 8.203) and the difference was statistically significant (p = 0.002). Conclusion: Elevation of joint line ≥5 mm from the pre-operative value has a negative impact on post-operative functional outcome in primary TKA.
