A comparative prospective study between stemmed versus an unstemmed tibial component in total knee arthroplasty in obese patients.
Article in European journal of orthopaedic surgery & traumatology : orthopedie traumatologie, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
backgroundThere is no consensus in the literature regarding the patients with obesity who do well with TKA, or this group is at risk of a variety of complications. Implant choices between the two types of implants which either long or standard stem can improve the likelihood that a patient with obesity will achieve high scores for function and quality of life after TKA.
methodsThis prospective clinical study included 200 patients who were categorized into two groups: group (1) traditional (standard) unstemmed cemented tibial tray (n = 100 patients) and group (2) stemmed cemented tibial tray with the cementless press-fit stem (n = 100 patients).
resultsThe average follow-up was (7.6 ± 1 years) (range from 6.5 up to 10 years). The average age of the stemmed group was 55.69 ± 8.45 and for the unstemmed group was 57.3 ± 7.8. The average BMI for the stemmed patients was 38.84 ± 3.89, while for the standard (unstemmed) group was 40.0 ± 3.95. Functional results showed significant improvement in both groups but more in the stemmed group (LS) as the difference and change between pre and post were more significant at long stem (P > 0.001).
conclusionBased on our results, there were significant improvements in both groups either stemmed or unstemmed TKA but more in the stemmed group which had higher functional outcomes compared to the unstemmed group. LEVEL OF EVIDENCE: IV.
