Harvest Technique Does Affect the Quality of Osteochondral Grafts: Histologic Evaluation Comparing Commercial Standards versus Scalpel Blade Technique.
Article in Cartilage, 2023. 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
objectiveWhile the percentage of viable cells is a major determinant of graft performance during osteochondral allograft (OCA) transplantation, the baseline chondrocyte viability at the periphery of osteochondral plugs is defined at the time of harvest. In this laboratory study, we aimed to determine the optimal technique for OCA plug harvest by evaluating commercial standard techniques compared to sharp blade harvest technique.
designOsteochondral explants were harvested from bovine and human samples using 3 different techniques: (1) standard OATS manual punch device (Osteochondral Autograft Transplant System OATS; Arthrex, Naples, FL), (2) powered trephine device, and (3) fresh scalpel blade. Chondrocyte viability and the dead area at the periphery of the tissue were evaluated by LIVE/DEAD staining. Safranin-O and fast-green were performed for structural evaluation.
resultsFor both bovine and human samples, the dead area at the periphery of the explant was significantly smaller after scalpel blade preparation compared to harvest with OATS (
conclusionOur study demonstrated that OCA plugs harvested with OATS and powered device lead to a significant mechanical injury at the periphery of the explants compared to a scalpel. We propose that the optimal technique for OCA harvest utilizes a combined approach incorporating a scalpel blade/circular scalpel to prepare the chondral surface and a powered trephine to prepare the osseous surface.
