Outcomes and motives for not proceeding with the second stage bilateral knee replacement: a comparison of cancelled and completed bilateral 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
backgroundStaged bilateral total knee arthroplasty (TKA) is a common treatment option for patients with bilateral symptomatic knee osteoarthritis, yet some patients do not proceed with their second procedure. Our study aimed to identify the rate and reasons why patients did not proceed with their second procedure and compare their functional outcomes, satisfaction and complication rates with those of patients who had completed a staged bilateral TKA.
methodsWe determined the proportion of patients who underwent TKA but did not proceed with planned surgery for the second knee within 2 years, and compared their satisfaction with surgery, improvement in the Oxford Knee Score (OKS) and complications between groups.
resultsOur study included 268 patients: 220 patients who underwent staged bilateral TKA and 48 patients who cancelled their second procedure. The most common reason for not proceeding with the second procedure was a slow recovery after the first TKA (43.2%), followed by functional improvement in symptoms in the unoperated knee negating the need for surgery (27.3%), poor experience with the first surgery (22.7%), treatment of other comorbidities necessitating cancellation of their second procedure (4.6%) and employment reasons (2.3%). Patients who cancelled their second procedure were noted to have a worse postoperative OKS improvement (
conclusionAbout one-fifth of patients scheduled for staged bilateral TKA declined to proceed with the second knee surgery within 2 years showing a substantially decreased functional outcome and satisfaction rate. However, more than one-quarter (27.3%) of patients noted improvements in their contralateral (unoperated) knee, such that a second surgery was no longer felt to be necessary.
