Severe preoperative pain, functional decline, and high anxiety levels hinder the efficacy of multidisciplinary interventions in patients who underwent primary 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
backgroundPatients experience clinically significant anxiety from the time they are recommended to undergo total knee arthroplasty (TKA). This study aimed to evaluate the efficacy of a preoperative intervention regarding anxiety levels in patients undergoing TKA for knee osteoarthritis (OA) and to evaluate whether patient characteristics affect the effectiveness of the intervention according to anxiety level.
methodsThis retrospective observational study recruited 89 patients who underwent TKA under general anesthesia for knee OA. The preoperative multidisciplinary intervention comprised rehabilitation education and an interview with an orthopedic surgeon regarding surgical preparation status. The State-Trait Anxiety Inventory (STAI)-X was administered before and after the preoperative intervention. Patients with baseline clinically meaningful state anxiety (CMSA) status were divided into a group that improved to a non-CMSA status (improved group) and a group that showed no change in CMSA status after the preoperative multidisciplinary intervention (non-improved group).
resultsThe mean STAI-X score significantly decreased from 46.5 points before the preoperative multidisciplinary intervention to 37.4 points after the intervention (P < 0.001). The proportion of patients with CMSA also significantly decreased from 36.0% before the intervention to 14.6% after the intervention (P < 0.001). The preoperative pain scale score was significantly higher in the non-improved group than in the improved group. The Tegner activity level was significantly lower in the non-improved group than in the improved group. The preoperative knee function scores, KSS and WOMAC scores, in the non-improved group were significantly worse than in the improved group. Additionally, the preoperative STAI-X score was significantly higher in the non-improved group than in the improved group.
conclusionsFor patients undergoing TKA, the implementation of a patient-specific preoperative multidisciplinary intervention, which consists of preoperative rehabilitation education and a surgeon interview, helps reduce preoperative anxiety. However, these preoperative multidisciplinary interventions may not be effective in patients who present with severe pain, poor functional status, or high anxiety levels before surgery.
