Recurrence in Adolescents With First-Time Acute Patellar Dislocation: Comparing Outcomes With and Without Osteochondral Fracture.

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
Background: Patellar dislocation is a common condition in adolescents, characterized by high rates of recurrent instability and an associated risk of osteochondral fracture (OCF). The risk of recurrent instability in this patient population, both with and without OCF, after a first-time dislocation remains unclear. Purpose: To determine and compare the incidence of recurrent patellar instability and the need for subsequent stabilization procedures between adolescents with and without OCF after first-time dislocation. A secondary objective was to report clinical outcomes of those patients. Study Design: Cohort study, Level of evidence, 3. Methods: This study was a retrospective analysis of adolescents who underwent their first-time patellar dislocation between 2016 and 2021 at a single orthopaedic hospital, with a minimum follow-up of 3 years. Patients were divided into 2 groups based on whether OCF was present: the OCF group and the non-OCF group. Baseline characteristics, radiographic measurements, and follow-up time were compared. Primary outcome measures included the incidence of recurrent patellar instability and the need for subsequent stabilization procedures. Secondary outcome variables included clinical outcome scores (such as Kujala score, Lysholm score, Tegner score, and International Knee Documentation Committee score), knee range of motion (ROM), as well as the ability to return to sport. Results: A total of 33 adolescents were included, with 15 in the OCF group and 18 in the non-OCF group. The only difference noted in baseline characteristics, radiographic measurements, and follow-up time was a higher tibial tuberosity-trochlear groove (TT-TG) in the OCF group (17.1 mm vs 14.5 mm; Conclusion: Adolescents with first-time patellar dislocation combined with OCF face a significantly higher recurrence rate (66.7%) compared with those without OCF, leading to increased subsequent stabilization procedures (53.3%). High-risk anatomic factors, such as elevated TT-TG values, further exacerbate instability. Targeted interventions are recommended for this high-risk population to reduce the recurrence of this condition.
