Functional quadriceps endurance, dynamic balance, and patient-reported recovery after total knee arthroplasty: a cross-sectional analysis of functional capacity and perceived disability.

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
Background: Functional quadriceps endurance is a key determinant of physical function after total knee arthroplasty (TKA), yet its relationship with patient-reported outcomes and the potential mediating role of mobility and balance performance remain underexplored. Objectives: To (1) examine the associations between functional quadriceps endurance and patient-reported outcomes (PROMs) after TKA, and (2) test whether dynamic balance and mobility mediate the relationship between endurance and disability. Methods: A cross-sectional study was conducted in 136 individuals (mean age 67.45 ± 6.83 years; 58 males) between 6 and 18 months post-TKA. Participants completed physical performance tests-including the 30-Second Chair Stand, Straight-Leg Raise (SLR), Timed Up and Go (TUG), Four-Square Step Test (FSST), Single-Leg Stance (SLS), and Y-Balance Test-along with PROMs (WOMAC, KOOS, PROMIS Pain Interference, LEFS). Participants were stratified into tertiles based on quadriceps endurance. Analyses included ANOVA, ANCOVA, multiple linear regression, and mediation models using Sobel tests. Results: Higher quadriceps endurance was significantly associated with better PROMs across all domains ( Conclusion: Quadriceps endurance is an independent predictor of pain, function, and daily activity outcomes in TKA patients, with dynamic mobility and balance mediating its effects on disability. These findings support targeting endurance and mobility in postoperative rehabilitation.
