A novel biomechanical measure to determine knee instability after ACLR: variability at knee rotational axis.
Article in Archives of orthopaedic and trauma surgery, 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
introductionHop distance tests are commonly used to determine when it is safe to return to sports (RTS), but symmetrical test results do not necessarily indicate the absence of biomechanical deficiencies. Three-dimensional motion analysis may quantify ongoing lower extremity instability following anterior cruciate ligament reconstruction (ACLR). MATERIALS AND
methodsWe estimated the instantaneous knee rotation axis during the landing phase of the triple hop test. The angular deviation in the orientation of the knee rotation axis between two successive instants was computed and used as a variability measure at the knee joint rotation in three dimensions.
resultsKnee flexion was less, the duration of the landing interval was shorter, and the variation at the knee rotation axis orientation over landing duration was higher on the operated side. We then classified the participants into two groups due to the threshold (above versus below 90%) defined at the Range of Motion-Limb Symmetry Index. Significantly shorter landing intervals and higher variation at the knee rotation axis orientation over the landing period at the operated side persisted in the below-threshold group only.
conclusionWe suggest an assessment of the variation in the orientation of the knee rotation axis over the hop test landing duration, which has the potential to be utilized for decisions in RTS at ACLR.
