Midterm results of a new personalized knee implant for total knee arthroplasty: implant survivorship and patient-reported outcome after five years' follow-up.
Article in European journal of orthopaedic surgery & traumatology : orthopedie traumatologie, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeThe Persona® system is a newly launched implant designed for total knee arthroplasty (TKA) with technical innovations intended for a better functional outcome and higher flexion range. The aim of this study is to evaluate midterm outcomes and survivorship of a cohort of patients with a minimum of 5-year follow-up and to confirm previous results described in the literature.
methodsA cohort of 91 knees (85 patients) that underwent a patella-preserving TKA with the Persona® implant and who were followed for a mean of 5.9 years' period was included in the study. Functional values were measured: Oxford Knee Score (OKS), Knee Society Knee score (KSKS) and Knee Society Function score (KSFS). Range of movement (ROM), lower limb axis correction, mobilization and complications were also registered at the last follow-up and underwent statistical analysis.
resultsWe found a low rate of complications or radiological changes with an implant-related revision rate of 2.19%. Mean results for PROMS were 44.21 ± 4 in OKS, 90.94 ± 2.4 in KSS and 97.88 ± 9.6 in KSFS. Mean postoperative ROM was 120.8º ± 12.37º. There was no change in implant positions at the final follow-up. We found radiolucent lines in 3 knees (3.29%).
conclusionAt a mean follow-up of 5.9 years, the implant-related cumulative percentage revision rate was 3.3% (2 of 91) at a mean follow-up of 5.9 years, with good clinical and functional results.
