“…Reports from radiology literature have highlighted the importance of quality reporting by experienced musculoskeletal radiologists [ 14 - 16 ]. To be of value, MRI of the knees should follow a specific protocol and should be performed and reported by experienced musculoskeletal radiologists [ 5 ].…”

Clinical examination, MRI and arthroscopy in meniscal and ligamentous knee Injuries – a prospective study

et al. 2008

Data from 565 knee arthroscopies performed by two experienced knee surgeons between 2002 and 2005 for degenerative joint disorders, ligament injuries, loose body removals, lateral release of the patellar retinaculum, plica division, and adhesiolysis was prospectively collected. A subset of 109 patients from the above group who sequentially had clinical examination, MRI and arthroscopy for suspected meniscal and ligament injuries were considered for the present study and the data was reviewed. Patients with previous menisectomies, knee ligament repairs or reconstructions and knee arthroscopies were excluded from the study. Patients were categorised into three groups on objective clinical assessment: Those who were positive for either meniscal or cruciate ligament injury [group 1]; both meniscal and cruciate ligament injury [group 2] and those with highly suggestive symptoms and with negative clinical signs [group 3]. MRI was requested for confirmation of diagnosis and for additional information in all these patients. Two experienced radiologists reported MRI films. Clinical and MRI findings were compared with Arthroscopy as the gold standard. A thorough clinical examination performed by a skilled examiner more accurately correlated at Arthroscopy. MRI added no information in group 1 patients, valuable information in group 2 and was equivocal in group 3 patients. A negative MRI did not prevent an arthroscopy. In this study, specificity, positive and negative predictive values were more favourable for clinical examination though MRI was more sensitive for meniscal injuries. The use of MRI as a supplemental tool in the management of meniscal and ligament injuries should be highly individualised by an experienced surgeon.

“…Imaging modalities used to evaluate the meniscus include MRI and computed tomography (CT) . MRI is the clinical standard for examining meniscus morphology, including detection of lesions and evaluation of treatment post‐operatively using native and contrast‐enhanced MRI . However, no studies have reported the correlations between meniscal GAG content and MRI signal.…”

We determined whether contrast-enhanced computed tomography (CECT) attenuation obtained using a μCT scanner correlated with the glycosaminoglycan (GAG) content and distribution in ex vivo bovine menisci. Bovine samples were immersed in different concentrations of the contrast agents CA4+ and Ioxaglate, and the μCT images were compared to Safranin-O staining. CA4+ and Ioxaglate diffusion-in kinetics and the correlation between their CECT attenuations and GAG content were investigated. CA4+ and Ioxaglate both reached steady state in the meniscal regions within 95 h, with tau values of 20.6 ± 3.98 and 25.9 ± 3.71 h (mean ± SD), respectively. Both agents diffused preferentially through the proximal and secondarily through the distal surface. The CA4+ CECT attenuation was strongly and positively correlated with the GAG content of the meniscus regions (R2 = 0.89, p < 0.001) at low concentrations (12 mgI/ml), while the Ioxaglate CECT attenuation was moderately and negatively correlated with the GAG content (R2 = 0.51, p = 0.03) at 60 mgI/ml. CECT can image ex vivo menisci, and the CA4+, compared to Ioxaglate, enhanced attenuation strongly correlates with the GAG content and distribution in bovine meniscus.

“…Die Methode ist nach Meyer et al (16) ebenfalls gut geeignet, begleitende Meniskusganglien und Nekrosezysten zu differenzieren. Lediglich im Bereich des Außenund Innenmeniskushinterhornes ergeben sich in verschiedenen Untersuchungen gehäuft Interpretationsfehler (2, 13,21,22). Ebenfalls scheint sich die Methode nicht zur postoperativen Verlaufskontrolle nach Meniskusnaht zu eignen (4).…”

We conclude, that by an experienced examiner a meniscal lesion can be diagnosed adequately by clinical examination alone. The different radiologists who did the MRI examination in our study belong to different outward departments and used different apparatus with sometimes insufficient quality of the pictures. Therefore the sensitivity and specificity of the MRI for meniscal lesions is markedly lower than in other studies of departments where a close cooperation between the radiologist and the orthopedic surgeon is performed.
