Mid- to long-term outcomes of all-arthroscopic allograft meniscus transplantation combined with cartilage repair.
Article in Journal of orthopaedic surgery and research, 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
objectiveTo evaluate the mid- to long-term clinical outcomes of all inside arthroscopic suture lateral meniscal allograft transplantation (MAT) combined with different cartilage repair techniques, microfracture (MF) or osteochondral autograft transplantation systems (OATS), in the treatment of lateral meniscal deficiency with concomitant lateral compartmental chondral lesions of the knee.
methodsA retrospective study was conducted on 22 patients who underwent arthroscopic lateral MAT combined with cartilage repair between June 2013 and December 2020 in the First Affiliated Hospital of Chongqing Medical University. All patients were diagnosed preoperatively by MRI and confirmed via arthroscopy to have lateral meniscal deficiency with local cartilage lesions of the lateral femoral condyle. The cartilage defects were less than 2 cm
resultsAll patients completed the follow-up. Lysholm, Tegner, and VAS scores improved significantly at 6 months, 1 year, 2 years, and 5 years postoperatively compared to preoperative values (P < 0.05), with sustained improvement observed through the final follow-up. MRI showed intact meniscal grafts in 20 cases (90.9%), while graft failure due to tear was identified in 2 cases. The overall rate of excellent or good cartilage repair (ICRS grading) was 59.1% (13/22). No major complications such as infection or common peroneal nerve injury were observed.
conclusionLateral meniscal allograft transplantation combined with microfracture or osteochondral autograft transplantation with all inside arthroscopic suture is a safe and effective treatment for patients with lateral meniscal deficiency and small-to-moderate local cartilage lesions, yielding sustained improvement in knee function, pain relief, and cartilage repair outcomes in the mid- to long-term.
