Does the preoperative presence of central sensitization affect sleep quality and pain after total knee arthroplasty?

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
Objectives: This study aims to investigate the presence of central sensitization before total knee arthroplasty (TKA) in patients with knee osteoarthritis, to explore its relationship with sleep quality after this surgery, and to evaluate postoperative pain intensity, neuropathic pain, anxiety, depression, and functional status. Patients and methods: Between May 2022 and May 2023, a total of 31 patients (8 males, 23 females; mean age: 68.1±2.8 years; range, 62 to 73 years) who underwent a radiographic examination, had Stage 3-4 osteoarthritis based on the Kellgren-Lawrence classification, and had TKA indications at the discretion of the orthopedic surgeon were included in this single-center, one-group, quasi-experimental, prospective study. The Central Sensitization Inventory (CSI) and International Physical Activity Questionnaire-Short Form (IPAQ) were used to evaluate patients scheduled for TKA due to osteoarthritis of the related joint. The Visual Analog Scale (VAS), painDETECT, the Pittsburgh Sleep Quality Index (PSQI), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the Hospital Anxiety and Depression Scale were applied to all patients preoperatively and at one and three months postoperatively. Results: The postoperative PSQI, VAS, and painDETECT scores were significantly higher in those with central sensitization compared to non-central sensitization group after surgery (p<0.001). The CSI score had a positive correlation with the PSQI, VAS, and painDETECT scores, and a negative correlation with the preoperative IPAQ score (p<0.05). Conclusion: Our study results suggest that, in patients with knee osteoarthritis waiting for TKA, central sensitization status has an adverse impact on postoperative pain and sleep quality.
