Evaluating Patient Satisfaction Outcome After Total Knee Arthroplasty Done at Our Hospital's Joint Replacement Registry, Egypt.

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
introductionTotal knee arthroplasty (TKA) is a highly effective intervention for enhancing function and quality of life in cases with advanced knee osteoarthritis. Although multiple factors have been identified as influencing TKA outcomes, it remains challenging to accurately predict which patients will experience dissatisfaction postoperatively, thereby complicating efforts to optimize their management. This study aimed to evaluate the patient satisfaction outcome after TKA done at our hospital's joint replacement registry using the updated Knee Society Scoring System.
methodThis retrospective observational study was conducted on 900 cases who underwent a TKA. The same surgeon consultant, head of the department, performed all the surgeries.
resultsSF-12 scores and total new knee society scoring (satisfaction subscale, expectation subscale, function activity subscale, and total score) were markedly higher at the end of follow-up than at the baseline (P < 0.05). A negative correlation was found between new knee society scoring, and age and body mass index(P < 0.05). A positive correlation was found between new knee society scoring, and duration of follow and SF-12 as P < 0.05. New knee society scoring was markedly higher in men than women (P = 0.011). New knee society scoring was markedly different among causes of arthroplasty (P = 0.005). DISCUSSION: An overall satisfaction rate was there among the studied cases regarding SF-12 score, which measures the activity and mentality of the cases postoperatively; in addition, most of the studied group show a notable improvement in new knee society score.
