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

introductionPatients with haemophilia typically achieve only approximately a 90° range of motion (ROM) following total knee arthroplasty (TKA), which still significantly affects their daily life.

aimStudies have indicated that the posterior tibial slope (PTS) and posterior condylar offset (PCO) are associated with ROM following TKA. However, it remains unclear whether these findings are applicable to patients with haemophilia, given their distinct skeletal anatomy compared to the general population.

methodsA retrospective review was conducted on 56 patients (71 knees) who underwent TKA at our centre from January 2018 to December 2022. Demographic information, viral infections, postoperative PTS, PCO, posterior condylar offset ratio (PCOR) and ROM at 1-year post-surgery were documented for each patient. We investigated the impact of PTS, PCO and PCOR on postoperative ROM using t-tests and regression analysis.

resultsOne year after TKA, patients with haemophilia demonstrated ROM of 89.61°. Larger PTS group exhibited a greater ROM compared to smaller PTS group. This phenomenon was also observed with PCOR. Multiple regression analysis uncovered a positive correlation between postoperative PTS (B = 0.933, p < 0.001) and PCOR (B = 22.417, p = 0.047) and postoperative ROM. Furthermore, postoperative pain showed a negative correlation with ROM (B = -5.377, p < 0.001), whereas preoperative ROM exhibited a positive correlation with it (B = 0.285, p < 0.001).

conclusionProperly increasing PTS and PCOR during surgery may lead to increased postoperative ROM for patients with haemophilia. Furthermore, effective postoperative pain management also aids patients in their recovery of ROM.
