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

purposeAlthough unilateral total knee arthroplasty (TKA) is successful in restoring function, there are concerns in relation to asymmetric gait patterns. Bi-cruciate retaining (BCR) TKA design preserves both anterior and posterior cruciate ligaments with the potential to restore normal joint kinematics. The purpose of this study was to investigate the in vivo three-dimensional (3D) kinematics of the knee in unilateral BCR TKA patients during gait.

methodsTwenty-nine unilateral BCR TKA patients were evaluated for both knees during treadmill gait using a combined computer tomography and dual fluoroscopic imaging system approach.

resultsSignificantly higher flexion (4 ± 6.7°) and internal rotation (4.3 ± 4.7°) and significantly lower adduction (2.5 ± 4.4°) during the stance phase of gait cycle were observed in the implanted side of unilateral BCR TKA patients. Significant asymmetric lateral/medial (3.2 ± 4.8 mm) and anterior/posterior (3.4 ± 4.1 mm) tibial translations were also measured during treadmill gait in this cohort of patients.

conclusionDespite maintaining anteroposterior stability, asymmetric knee motion persisted in in vivo unilateral BCR TKA patients during gait. The results of the current study suggested that the knee motion symmetry during gait was not restored in patients with unilateral BCR TKA.
