Eight-Year Clinical, Radiological, and Survival Outcomes of Knee Chondral Lesions Treated With High-Density Autologous Chondrocyte Implantation.
Article in Cartilage, 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
BackgroundArticular cartilage lesions of the knee are difficult to manage due to their limited healing capacity. High-Density Autologous Chondrocyte Implantation (HD-ACI) has emerged as a promising treatment for symptom relief and functional recovery.MethodsThis retrospective study included 124 patients (88 men, 36 women; median age 35.5 years) with symptomatic chondral lesions of the knee treated with HD-ACI between 2010 and 2016. Patients were followed for up to 8 years. Visual Analogue Scale (VAS) for pain, International Knee Documentation Committee (IKDC) scores for knee function, and MOCART scores based on MRI evaluations of cartilage repair tissue were used for clinical assessment.ResultsPain significantly decreased from a mean VAS of 6.7 to 1.1 at 8 years (p<0.001). IKDC scores improved from 39.4 to 81.6 (p<0.001), being higher than the minimal clinically important difference (MCID). MOCART scores progressively increased over time. Knee mobility in both extension and flexion showed statistically significant improvement. Adverse events were mild and infrequent. Kaplan-Meier analysis showed an implant survival of 97.5% and an overall treatment survival of 92.6% at 8 years.ConclusionsHD-ACI is a safe and effective treatment for knee cartilage lesions, with long-term improvements in pain, joint function, confirmed clinically and radiologically.
