“…Magnetic resonance arthrography increases the accuracy of the diagnosis of operated meniscus compared with the MRI without arthrography. 3,24 Statistics Statistical analysis was done using the SPSS 11.0 software package (SPSS Inc, Chicago, Illinois). The calculations between the differences of means were done by an analysis of variance, paired-sampled t test, and those of the frequencies by the x 2 test.…”

“…However, the diagnostic accuracy of conventional MRI is low, because both the initial fibrovascular and the later mature fibrocartilagenous scar produced persistent increased signal intensity on MR images after six months. Hantes et al [19] assessed the healing process of the meniscal repair by indirect MRI at three, six, and 12 months after the operation. A postoperative hypersignal was found in each of the 20 patients involved in this study at three months.…”

Purpose The purpose of this study was to assess the MRI features of the all-inside repaired meniscus in the long-term. Methods Among 27 consecutive all-inside arthroscopic meniscal repairs, 23 patients aged 25±5 years at the time of surgery were reviewed at a median follow-up of 10±1 years. Retrospective clinical examinations and imaging assessments using a 1.5-T MRI after all-inside arthroscopic meniscal repair were conducted. Results At follow-up, Lysholm and IKDC averaged 89±11 and 95±8, respectively. MRI examinations revealed no meniscal signal alteration in three patients (13 %), a vertical signal located in the previously torn area in seven (30 %), a horizontal grade 3 in nine (39 %), and a complex tear (grade 4) in four (17.5 %). There were no differences between medial and lateral menisci (p=0.15), stable and stabilised knees (p=0.56). Conclusions Several abnormal vertical and/or horizontal hypersignals are still present on MRI examination ten years after arthroscopic all-inside meniscal repair. The appearance of early signs of osteoarthritis is rare, suggesting a chondroprotective effect of the repaired meniscus.

“…Indirect MR arthrography has been used in the knee to assess the postoperative meniscus, [27][28][29] autologous chondrocyte implants, 30,31 and biodegradable scaffolds for the treatment of osteochondral lesions. 32 This technique is based on the concept that injected intravenous contrast within the plasma will rapidly form a steady state with the intraarticular fluid due to bulk flow and diffusion.…”

MR and CT arthrography are important imaging modalities for the assessment of the knee in certain situations. Indications for MR arthrography of the knee include assessment of the postoperative meniscus, the presence of chondral and osteochondral lesions, and the presence of intra-articular bodies. The major indication for CT arthrography is evaluating suspected internal derangement in patients who are unable to undergo MRI. In addition to reviewing the established clinical indications for MR and CT arthrography of the knee, the commonly used techniques, normal variants that can simulate disease, and the most commonly found pathologies that can be diagnosed with these modalities are discussed. Potential indications that are not currently well established in the literature including the evaluation of anterior cruciate ligament injury and autologous chondrocyte implants are examined. Where appropriate, the literature on controversial topics or diagnoses is reviewed. The use of conventional imaging versus CT and MR arthrography is also compared.
