The purpose of this study is to correlate the findings of Magnetic Resonance Imaging with Arthroscopy in internal derangements of knee and to assess the sensitivity, specificity and accuracy of Magnetic Resonance Imaging in comparison to Arthroscopy. METHODS AND MATERIALSFifty six patients with history of suspected internal derangement of knee were evaluated prospectively with MRI and correlated with arthroscopy during a one and half a year period from March 2012 to September 2013.1.5 Tesla MRI machine using a closed extremity coil is used. Sequences used in MRI of the knee include Turbo-spin echo (TSE), FFE (Gradient echo) and Short Tau Inversion Recovery (STIR) sequences in Axial, Sagittal and Coronal planes using a slice thickness of 3 mm with a 0.3 mm slice gap. Arthroscopy of the knee with standard anteromedial and anterolateral portals with the patient in supine position done in all the cases. RESULTSThe diagnostic sensitivity, specificity SUMMARY AND CONCLUSION MRI is a useful non-invasive modality having high sensitivity, specificity and accuracy in diagnosing cruciate ligament and meniscal injuries.  MRI should be considered as the first line of investigation in all patients with suspected internal derangements of knee.  MRI being easily available and non-invasive is useful as a pre-operative screening modality, thus improves the quality of diagnostic and therapeutic arthroscopies and further reduces the morbidity.  Arthroscopy is the standard diagnosing tool in all patients with suspected internal derangements of knee.  Arthroscopy should be reserved for selected cases where intervention is required and as a problem solving tool.

Background: The knee joint is a common site of injury, mainly due to trauma, repetitive activities and sports activities. Multiple imaging modalities are currently used to evaluate pathologic conditions of the knee. Magnetic resonance imaging has a better soft tissue contrast and multi planar slice capability, which has revolutionized and has become the ideal modality for imaging complex anatomy of the knee joint. Another advanced modality in the management of IDK is arthroscopy, which can be used in its dual mode, either as diagnostic and/or as therapeutic tool.Methods: Cases were taken according to inclusion and exclusion criteria i.e., patients with knee problems more than 6weeks old, with symptoms of locking of knee, patients with undiagnosed knee pain and knee injury. Only patients between 15-50 years are included in the study. Patients with signs of infection, with osteoarthritis, ankylosis, and patients on ATT were excluded from the study.Results: In our study of 25 cases, there were 20 male and 5 female patients with age ranging from 15 years to 50 years with most patients in between 21-30 years. 11 cases admitted were sport injuries, 14 had motor vehicle accidents. Right side being more common side affected.Conclusions: In conclusion the present study supports that clinical diagnosis is of primary necessity and MRI is additional diagnosing tool for IDK.

Background: Apart from clinical examination multiple modalities (conventional radiography, MRI and arthroscopy) are currently used to evaluate knee injuries. This study is intended to compare the sensitivity and specificity of MRI in correlation of arthroscopy in diagnosing of knee injuries.Methods: This is a prospective study involving 51 patients with history of knee injuries who were admitted in the Department of Orthopaedics, Command Hospital, Kolkata, India from April 2013 to June 2014. MRI of the knee joint was done for all these patients either before or after admission. The patients were then subjected to diagnostic and therapeutic arthroscopy. Statistical analysis was used to calculate the sensitivity, specificity, positive predictive value and the negative predictive value, in order to assess the reliability of the MRI results.Results: The sensitivity and specificity of MRI with respect to arthroscopy in anterior cruciate ligament tear is 87.5% and 66.6%. Positive predictive value is 87.5%. Negative predictive value is 66.6%. Accuracy is 81.82%. The sensitivity and specificity of MRI with respect to arthroscopy in medial meniscal tears is 85.7% and 70.8% respectively. Positive predictive value is 63%, negative predictive value is 89.4%, accuracy is 76.3%.Conclusions: The present study supports that MRI is helpful in diagnosing medial meniscal and anterior cruciate ligament injuries. The negative predictive value of a MRI was found to be high for all structures of the knee joint and hence a MRI can be used to exclude pathology, thus sparing patients from expensive and unnecessary surgery.
