Determinants of patient satisfaction 5 years after dual-mobility trapeziometacarpal joint implant 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
introductionThe primary aim of this registry-based case series was to identify determinants of patient satisfaction 5 years after dual-mobility trapeziometacarpal joint (TMJ) implant arthroplasty. Secondary aims included the assessment of 5 year outcomes and implant survival.
methodsPatients who underwent primary implantation of a dual-mobility TMJ prosthesis were included. Satisfaction at 5 years was assessed using a five-point Likert scale and analysed using a top-box approach. Determinants of being 'very satisfied' were evaluated using univariate logistic regression. Pain (numeric rating scale), hand function (brief Michigan Hand Outcomes Questionnaire, MHQ) and key pinch strength were assessed. Changes in outcomes between baseline and 5 years were analysed using a linear mixed-effects model. Implant survival was estimated using the Kaplan-Meier method.
resultsOf the 125 patients who underwent surgery, 108 were available for the 5 year analysis and 94 completed the satisfaction questionnaire. Of the latter, 87 (93%) were 'satisfied' or 'very satisfied' with the treatment outcome. Lower pain levels and higher brief MHQ scores at 5 years were significantly associated with being 'very satisfied'. Baseline characteristics, complications and revision surgery were not associated with satisfaction. Baseline pain, brief MHQ and key pinch strength improved significantly by 5 years. Five revision surgeries occurred, resulting in an estimated 5 year implant survival of 96% (95% CI 92 to100).
conclusionOur results support existing evidence that dual-mobility TMJ arthroplasty yields high patient satisfaction, significant clinical improvement and excellent implant survival at 5 years. Pain relief and improved hand function appear to be key determinants of patient satisfaction. LEVEL OF EVIDENCE: IV.
