Mid-term results of treatment of traumatic knee osteochondral fractures in pediatric and adolescent population with bioabsorbable implants.

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
introductionThe use of bioabsorbable implants for the fixation of osteochondral knee fractures remains controversy. The objective of this study is to analyze their clinical, radiological, patient-reported outcomes (PROMs), and return-to-sport (RTS) outcomes in children and adolescents.
methodsWe performed a retrospective study including 33 skeletally immature patients (33 knees) with osteochondral knee fractures. Demographic, magnetic resonance imaging (MRI), clinical and surgical data (number of implants and associated procedures) were collected. The detached fragment was using SmartNail® bioabsorbable implants. Radiological results were shown according to the MOCART 2.0 knee score. Patients completed the Knee Injury and Osteoarthritis Outcome Score (KOOS), Kujala Score, Lysholm Score, Tegner Activity Scale, and UCLA Activity Level questionnaires.
resultsThe mean age at surgery was 13.5 ± 2.2 years. The most frequent location was the patella (54.5%), followed by the lateral femoral condyle (33%). After a mean follow-up of 5.9 years (SD 3; range 2-14) and with a current mean age of 19.4 ± 3.9 years, most lesions healed with good cartilage appearance (mean MOCART score 91.67 ± 7.25, range 70-10) and no material failure detected on MRI, the RTS rate at the same level was 88%, and the mean PROMs results were: KOOS 89.1 ± 12.9, Kujala Score 91.3 ± 8.8, Lysholm Score 84.8 ± 16, Tegner Activity Scale 6.8 ± 1.5 and UCLA Activity Level 7.3 ± 1.3.
conclusionFixation of traumatic osteochondral knee fractures in children and adolescents with bioabsorbable implants obtains good radiological results, as well as favorable PROMs and RTS rates, after a mean follow-up of 5.9 years.
