Single-Stage Treatment of a Patellar Osteochondral Defect in an Adolescent Using Autologous Minced Cartilage - Platelet-Rich Plasma Scaffold Technique: A Case Report and Technical Considerations.
Article in Journal of orthopaedic case reports, 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
Introduction: Osteochondral defects of the patella in pediatric patients are rare but clinically significant due to pain, mechanical symptoms, and potential long-term sequelae. Traditional two-stage approaches, such as autologous chondrocyte implantation, are often avoided in younger patients due to surgical burden and cost. This case report presents a single-stage biologic cartilage repair using autologous minced cartilage and a biologic scaffold (AutoCart, Arthrex) in a 14-year-old male with a symptomatic osteochondral defect in the patella. Case Report: The technique involves arthroscopic harvest of autologous minced cartilage, intra-operative preparation of platelet-rich plasma (PRP), and application of a cartilage-PRP-BioCartilage matrix. Cancellous bone graft was also added in this case due to the large size of the defect. Conclusion: At 6 months post-operative, the patient was asymptomatic, had returned to full activity, and magnetic resonance imaging confirmed excellent defect filling with no complications.
