Correlation between gait analysis parameters and joint function prognosis during rehabilitation after anterior cruciate ligament reconstruction: a retrospective study.

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 evaluate changes in gait parameters following autograft hamstring anterior cruciate ligament (ACL) reconstruction and their association with knee function recovery and to explore the predictive value of gait parameters in clinical assessment.
methodsA total of 186 patients who underwent ACL reconstruction between January 2020 and September 2023 were enrolled. Gait analysis and knee function assessments (Lysholm, International Knee Documentation Committee [IKDC], and Tegner scores) were performed pre- and postoperatively. Gait data were collected using the Sennotech Insole X 1.0 system. Multivariate linear regression and logistic regression models identified significant gait predictors, and function prediction models were constructed and evaluated using Receiver Operating Characteristic (ROC) curves and decision curve analysis (DCA).
resultsPostoperative gait parameters significantly improved, particularly stride length, step height, and landing impact force (all P < 0.05). Knee function scores, including Lysholm and IKDC, significantly improved, while the Tegner score declined (all P < 0.001). Stride length was positively correlated with Lysholm and IKDC scores, while impact force was negatively correlated with IKDC. Multivariate regression analysis identified stride length and lift angle as significant predictors of Lysholm and IKDC scores, while flat phase and impact force were negatively associated with Tegner score. The predictive model demonstrated AUC values of 0.73 and 0.66 for the training and testing sets, respectively. DCA confirmed the clinical utility of the model.
conclusionGait improvements following ACL reconstruction are closely linked to knee function recovery. Key gait parameters serve as objective predictors and can guide personalized rehabilitation planning.
