Midterm results of intra-articular stromal vascular fraction injection for the treatment of knee osteoarthritis.
Article in Knee surgery, sports traumatology, arthroscopy : official journal of the ESSKA, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposeThis study aimed to evaluate the safety and efficacy of intra-knee stromal vascular fraction (SVF) injection in patients with symptomatic knee osteoarthritis at the midterm (3-year) follow-up.
methodsSVF injection was applied to 25 knees of 20 patients. Eighteen patients (90%) were female, and the means ± standard deviations of age was 61.9 ± 7.8 (range, 50-76) years. Patients who received conservative treatment for at least 6 months and had radiographic Kellgren-Lawrence (K-L) grades 2 and 3 varus gonarthrosis were included in the study. SVF was obtained from the umbilical region by liposuction using local anaesthesia. Patients were followed-up for 36 months. Their visual analogue scale (VAS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and Lysholm scores were evaluated before and at 6, 12, 24 and 36 months post-SVF injection.
resultsA statistically significant improvement (p < 0.05) was observed in VAS, WOMAC and Lysholm scores at the first 2-year follow-up compared to baseline. However, no statistically significant difference (n.s.) was observed in VAS, WOMAC and Lysholm scores at the 3-year follow-up compared with baseline.
conclusionIntra-articular SVF injection decreased pain and significantly improved the functional outcomes in the first 2 years in knees with grade 2-3 osteoarthritis; however, these positive effects of the injection disappeared in the 3rd year. Although short-term successful results of SVF have been reported in the literature, prospective studies are needed for medium- and long-term results.
