Midterm Outcomes of Primary Osteochondral Autograft Transfer for Symptomatic Chondral Defects of the Knee.

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: While the deleterious long-term effects of microfracture are well documented, studies examining the long-term clinical outcomes in patients treated with osteochondral autograft transfer (OAT) are scarce. Purpose: To assess the mid- and long-term clinical outcomes of primary OAT performed for the treatment of symptomatic articular cartilage lesions of the knee. Study Design: Case series; Level of evidence, 4. Methods: The medical records of 63 patients who underwent primary OAT were retrospectively queried from an institutional cartilage registry. Patient-reported outcome measures (PROMs) for patients treated with OAT from the practice of 6 fellowship-trained knee specialists were recorded. Patients with symptomatic articular cartilage lesions of the medial or lateral femoral condyle or trochlea who were treated with OAT were included. All patients had preoperative baseline PROMs; the minimum follow-up was 2 years. Exclusion criteria were previous ipsilateral knee surgical procedures, generalized osteoarthritis, revision cartilage procedures, previous total meniscectomy, and history of inflammatory arthropathy. Clinical outcomes, reoperation rates, and conversion to arthroplasty were analyzed. Results: The mean patient age was 27.4 ± 12.4 years (range, 11-56 years), and 23/63 (31.7%) were female. The mean follow-up was 5.7 ± 3.2 years (range, 2-16 years). The mean lesion size was 2.3 ± 1.6 cm Conclusion: Primary OAT is an effective and durable cartilage restoration procedure for some patients with symptomatic knee cartilage lesions at mid- to long-term follow-up, with a majority of patients demonstrating sustained improvements in clinical outcomes and achieving the MCID. However, a clinically important surgical failure rate exists, with up to one-third of patients needing a revision cartilage restoration procedure and only one-third of patients achieving the SCB for the IKDC score at the 10-year follow-up.
