Osteochondral Lesions of the Talus Treated With Particulated Juvenile Cartilage Allograft in the Active Duty Military Population.
Article in Foot & ankle orthopaedics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Osteochondral defects (OCDs) of the talus frequently affect young, active individuals and carry a risk of chronic pain and joint degeneration. Particulated juvenile cartilage allograft (PJCA), harnesses the proliferative capacity of juvenile chondrocytes to restore hyaline cartilage without donor-site morbidity. This study evaluates the structural, clinical, and functional outcomes of PJCA implantation in active-duty military patients. Methods: We retrospectively reviewed 10 service members (10 male, mean age 28.4 years) who underwent arthroscopic PJCA implantation for symptomatic talar OCDs. Outcomes included defect dimensions and volume on magnetic resonance imaging (MRI), Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) scores, visual analog scale (VAS) for pain, and Foot and Ankle Ability Measure (FAAM) subscales. Statistical analyses employed Wilcoxon signed-rank and Friedman tests (SPSS 28.0), with significance set at Results: Median follow-up was 15.0 months (range 13.5-18.2). Lesion volume decreased from 0.77 to 0.02 cm³ ( Conclusion: In this high-demand cohort, PJCA implantation was associated with radiographic evidence of defect fill, pain relief, functional restoration, and return to activity without donor-site morbidity. Despite the study's retrospective design and moderate follow-up, these findings support PJCA as a promising option for talar OCD repair. Prospective, randomized trials with extended follow-up are warranted to confirm durability and efficacy against established techniques. Level of Evidence: Level IV, retrospective case series.
