1 · What the graph read from it

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.

2 · The registry

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: Focal chondral and osteochondral defects in the knee are often difficult to treat. One solution is the use of osteochondral allograft (OCA) transplantation. The literature deliberates lesions located in the medial femoral condyle (MFC), but little is discussed regarding the lateral femoral condyle (LFC). Purpose: To compare graft survivorship and patient-reported outcomes (PROs) among patients who underwent OCA transplantation of the LFC to the MFC. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 319 patients who underwent primary OCA transplantation of the LFC (n = 111) and MFC (n = 208) were identified. Reoperations were recorded, and OCA failure was defined as allograft removal. PROs included the Knee injury and Osteoarthritis Outcomes Score (KOOS), the International Knee Documentation Committee (IKDC) score, the modified Merle d'Aubigné-Postel score, and satisfaction. Results: Patients with MFC grafts were older than those with LFC grafts (33 and 26 years, respectively; Conclusion: OCA transplantation of the LFC demonstrates high graft survivorship and significant improvement in PROs at mid-term follow-up. Clinical outcomes, reoperation rates, and survivorship were comparable to OCA transplantation of the MFC. These findings suggest that OCA transplantation of the LFC represents a reliable treatment option in appropriately selected patients.
