Investigating the dynamic relationship between joint function outcomes and kinesiophobia following total knee arthroplasty.
Article in Frontiers in psychology, 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
Objective: To investigate the temporal trends and bidirectional predictive relationships between joint function outcomes and kinesiophobia in patients following total knee arthroplasty (TKA). Methods: Using a convenience sampling method, 242 patients who underwent TKA in the orthopedics departments of two Grade A Tertiary hospitals in Panzhihua City between October 2024 and March 2025 were selected as study participants. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Tampa Scale for Kinesiophobia-11 (TSK-11) were used to assess joint function and kinesiophobia at 1 month (T1), 3 months (T2), and 6 months (T3) postoperatively. A cross-lagged analysis was employed to analyze the causal relationships between the variables. Results: Joint function in TKA patients improved significantly over time, while kinesiophobia levels gradually decreased, with statistically significant differences in scores across all time points ( Conclusion: We found a bidirectional relationship between joint function and kinesiophobia during TKA recovery, with the dominant influence shifting from kinesiophobia early on to joint function later. This suggests that rehabilitation strategies should be phased, initially addressing fear and later focusing on functional training to optimize outcomes.
