1 · What the graph read from it

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.

2 · The registry

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

Inverse kinematic alignment (iKA) is an emerging technique in total knee arthroplasty (TKA) that aims to restore the patients' native tibial joint line obliquity with femoral resections adjusted to balance the knee. By emphasizing joint line restoration and patient-specific balancing, iKA has gained interest as a potentially favorable alternative to traditional alignment techniques. This step-by-step surgical technique aims to outline the essential principles of iKA in robotic-assisted TKA. The method prioritizes an anatomic tibia resection and then a tensioner-based gap balancing technique to recreate natural kinematics. Since the technique is applicable to a wide range of patients and can be integrated to a variety of robotic platforms, iKA offers a promising pathway to standardize personalized alignment in TKA.
