Recommendations of an international Delphi study group for total knee arthroplasty in obese patients.

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) in obese patients poses multiple challenges and there is a lack of consensus on various aspects of TKA in this patient population. This study is a modified Delphi consensus study of international experts to provide recommendations on TKA in obese patients. MATERIALS AND
methodsThe consensus statements were generated using an anonymized two-round modified Delphi questionnaire, sent to an international panel of 53 knee surgeons, with an 80% agreement being set as the limit for consensus. The responses were analysed using descriptive statistics, with median as the measure of central tendency. Anonymized feedback was provided to all panellists based on responses from previous rounds to help generate the consensus.
results9 statements reached a consensus: WHO classification (87%), BMI cut-off for single-stage bilateral TKA (92%), use of tibial stem (84%), medial parapatellar approach (92%), same surgical approach as non-obese TKA (92%), inherent malnutrition (82%), higher risk of aseptic loosening in BMI class 3 (81%), need for time interval between bilateral TKA (88%), and consensus against leaving the knee in slight flexion (82%). The panel was unable to reach a consensus on 17 statements.
conclusionThis indicates lack of consensus on a majority of issues among experts and further research is required in this field to address evidence gaps, so we can improve our management of this increasing cohort of patients undergoing TKA. The statements reaching consensus form an important set of recommendation to improve patient selection and outcomes. Level of evidence Level V.
