Does Total Knee Arthroplasty Affect Ankle and Hindfoot Alignment? A Prospective Study on Functional and Radiological Outcome.
Article in Indian journal of orthopaedics, 2025. 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
Purpose: To maintain a plantigrade foot, knee deformity prompts compensatory hindfoot deformity. TKA realigns the knee correcting hip-knee angle (HKA) However, the consequential impact of severe varus on ankle and foot has been inadequately investigated in contemporary literature. Materials and Methods: The study consisted of 66 patients (87 knees) who underwent TKA. The radiological parameters assessed were hip-knee angle (HKA), tibial plafond inclination angle (TPIA), tibio-talar tilt angle (TTTA) and talar inclination angle (TIA). Functional assessment was done with AOFAS score pre-operatively and at 2-year follow-up. The paired Results: HFA, TPI, TTT, and TIA post-TKA showed statistically significant correction ( Conclusion: TKA improves ankle and hindfoot alignment both radiologically and functionally. However, any persistent malalignment in the ankle and hindfoot can lead to patient dissatisfaction.
