“…It doesn't expose the patient to harmful radiations and appears to be without any risk to the patient. Patients diagnosed with meniscus tears on MRI but are not present arthroscopically may be due to misdiagnosed meniscal cysts, mucoid degeneration or a simple misinterpretation of normal knee anatomy or may be due to inadequate arthroscopic techniques (Syal & Chudasama, 2015). Poor visualization of anterior or posterior cruciate ligament injuries may be due to partial volume effect and problems in imaging technique which use contiguous slides.…”

In the modern era of medicine, magnetic resonance imaging (MRI) has become an indispensable part in diagnosing knee injuries.Due to an increased dependence and reliance on MRI,clinical findings are often ignored and this leads to a neglect in diagnosing ligament injury. Considering a highly variable result in clinical findings & less studies being performed in Indian population we did an agreement study comparing the role of clinical examination,MRI findings and diagnostic arthroscopy in the diagnosis of traumatic chronic anterior cruciate ligament & meniscal injuries in our tertiary care hospital. In our prospective study we included 267 patients with anterior cruciate ligament, medial meniscus and lateral meniscus injuries.First these patients were examined clinically,then subjected to an MRI scan and arthroscopic surgery.Here we report a superior sensitivity and specificity of clinical examination in comparison to MRI scan for diagnosis of medial meniscal tears. For the diagnosis of anterior cruciate ligament (ACL) and lateral meniscus injury the results were found to be aequivocal.We recommend that when suspected clinically, a normal MRI should not be considered as a sufficient evidence to defer an arthroscopy in knee injury patient.

“…The examination under anesthesia and visual investigation at the knee arthroscopy are the gold standard by observing the internal structure of the joint, but most patients undergo magnetic resonance imaging (MRI) before arthroscopic treatment 6 . MRI is an effective method for the diagnosis of knee injury because it’s non-invasive and lacks of ionizing radiation to the patients 7 , 8 . It also minimized the opportunity for unnecessary arthroscopic surgery, which required high financial needs and possibly trauma 9 .…”

To evaluate the diagnostic accuracy of a new modified MR dual precision positioning of thin-slice oblique sagittal fat suppression proton density-weighted imaging (DPP-TSO-Sag-FS-PDWI) sequence in detecting ACL injuries and its grades compared to standard sequences using arthroscopy as the standard reference. 42 patients enrolled in this retrospective study received the 1.5-T MRI with standard sequences and the new modified DPP-TSO-Sag-FS-PDWI sequence, and their arthroscopy results was recorded. The Mc Nemer-Bowker and weighted Kappa was performed to compare the consistency of MRI diagnosis with arthroscopic results. Finally, the diagnostic accuracy was calculated based on the true positive, true negative, false negative and false positive values. The diagnostic consistency of the DPP-TSO-Sag-FS-PDWI were higher than standard sequences for both reader 1 (K = 0.876 vs. 0.620) and reader 2 (K = 0.833 vs. 0.683) with good diagnostic repeatability (K = 0.794 vs. 0.598). Furthermore, the DPP-TSO-Sag-FS-PDWI can classify and diagnose three grades of ACL injury [the sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value were more than 84%], especially for grade II injury as the PPV was superior for reader 1 (92.3% vs. 53.9%) and reader 2 (84.6% vs. 69.2%). The new modified DPP-TSO-Sag-FS-PDWI sequence can display the ACL injury on one or continuous levels by maximizing the acquisition of complete ligament shape and true anatomical images, and excluding the influence of anatomical differences between individuals. It can improve the diagnostic accuracy with good repeatability and classify three grades of the ACL injury.
