Painful Knee

Background: Painful knee is considered as one of the most common causes of morbidity and disability affecting all age group. It happens due to varied reasons ranged from injury to various disease processes. The present study documented the magnetic resonance imaging (MRI) findings in painful knee.Methods: A hospital based cross-sectional study was conducted among 100 painful knee patients referred to the Radiodiagnosis department of the Midnapore Medical College of West Bengal for evaluation. MRI scans performed using GE 1.5 Tesla  MRI scanner. Results were expressed in terms of numbers and proportions.Results: The commonest soft tissue lesion found was meniscal tears which mainly involved posterior horn of the medial meniscus and of grade 2 nature. In case of any injury, vertical meniscal tear was found the commonest type. Tear was found the commonest lesion involved the anterior-cruciate ligament (ACL), mostly acute in nature while partial tear commonly found in posterior-cruciate ligament (PCL). Nearly one-third (30%) had features of bone contusions; mostly tibia followed by lateral femoral condyle. Popliteal cyst was the commonest cystic lesion and was associated with effusions and meniscal tears while patello-femoral compartment mostly involved by the osteo-arthritic process.Conclusions: MRI is an ideal, non-invasive and more precised imaging technique for the radiological evaluate of the painful knee condition for better clinical management.

SummaryTo document the use of and to estimate the accuracy of magnetic resonance (MR) imaging for detection of late meniscal tears in dogs with cranial cruciate ligament injury treated with tibial tuberosity advancement (TTA).Medical records of dogs that had TTA followed by stifle MR imaging for suspected meniscal tear and subsequent arthrotomy were reviewed retrospectively. Magnetic resonance images were reviewed independently by an observer blinded to clinical information who classified menisci as torn, abnormal but intact, or normal. Magnetic resonance and surgical findings were compared.Eight stifles from large breed dogs were included. Six stifles had a medial meniscal tear identified in MR images and later confirmed surgically. In the remaining two stifles, the menisci appeared intact in MR images and no tear was identified at subsequent arthrotomy. Lateral menisci in all stifles appeared intact in MR images and were considered normal at surgery. Susceptibility artefacts associated with TTA implants were present in all images but did not adversely affect interpretation of intra-articular structures.Magnetic resonance imaging appears to be accurate for diagnosis of late meniscal tears. Artefacts associated with TTA implants did not prevent evaluation of critical intra-articular structures. Further investigation with MR imaging should be considered when late meniscal tear is suspected following TTA.

Meniscus Tears

Magnetic resonance imaging (MRI) has been widely used for the diagnosis of meniscal tears, but its diagnostic accuracy, depending on the type and location, has not been well investigated. We aimed to evaluate the diagnostic accuracy of MRI by comparing MRI and arthroscopic findings. Preoperative 3.0-T MRI and arthroscopic findings from 2005 to 2018 were reviewed to determine the presence, type, and location of meniscus tears. In addition, subgroup analysis was performed according to anterior cruciate ligament (ACL) injury. The exclusion criteria were as follows: (1) Inflammatory arthritis, (2) other ligament injuries, (3) inability to classify meniscal tears due to degenerative arthritis, (4) over 90 days from MRI to surgery, and (5) incomplete data. Of the 2998 eligible patients, 544 were finally included. The sensitivity and specificity of MRI in determining medial and lateral meniscus tears were 91.8% and 79.9%, and 80.8% and 85.4%, respectively. The accuracy of MRI in the ACL-injured group was lower than that in the ACL-intact group (medial meniscus: 81.7% vs. 88.1%, p = 0.041; 72.9% vs. lateral meniscus: 88.0%, p < 0.001). MRI accuracy was low for the longitudinal tears of the posterior horn of the medial meniscus in the ACL-injured group. MRI could be a diagnostic tool for meniscus tears, but has limited accuracy in their classification of the type and location. Hence, care should be taken during arthroscopic assessment of ACL-injured patients due to low diagnostic accuracy of preoperative MRI.

Abstract Background: Magnetic resonance imaging (MRI) has been recognized as the imaging method for non-invasive evaluation of knee pathology, particular meniscus and ligaments. Objective: Compare the sensitivity, specificity, and accuracy of MRI in the detection of meniscal tears with arthroscopy. Material and methods: Twenty-seven patients who were diagnosed as meniscal tear on arthroscopy with preoperative MRI were included in this study between January 2003 and June 2008. MRI was performed with a 1.5 Tesla Signa Horizon Echospeed MRI for eight patients between January 2003 and June 2005 and a 1.5 Tesla Signa Excited HD MRI for nineteen patients between July 2005 and June 2008. The location of meniscal tear was evaluated by studying three areas: anterior horn, body and posterior horn. Sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) of the anterior horn, body, posterior horn and overall meniscus were calculated. Results: The sensitivity of MRI for detecting meniscal tears at the anterior horn, body, posterior horn, and overall medial meniscus was 42.9%, 87.5%, 94.1%, and 81.3%, respectively. The specificity was 95.0%, 84.2%, 81.8%, and 88.0%, respectively. The accuracy was 81.5%, 85.2%, 89.3%, and 85.4%, respectively. The PPV was 75.0%, 70.0%, 88.9%, and 81.2%, respectively. The NPV was 82.6%, 94.1%, 90.0%, and 88.0%, respectively. The sensitivity of MRI for detecting meniscal tears at the anterior horn, body, posterior horn and overall lateral meniscus was 0%, 100%, 85.7%, and 80.0%, respectively. The specificity was 100%, 100%, 90.5% and 97.2%, respectively. The accuracy was 96.0%, 100%, 90.5%, and 97.2%, respectively. The PPV was 100%, 75% and 80%, respectively. The NPV was 96.3%, 100%, 95.0%, and 97.2%, respectively. Conclusion: MRI is a helpful technique to detect meniscal tear with different sensitivity and accuracy on the meniscal location.

♦ ACL tear: abnormal fibres, tibial translation, PCL/patella tendon buckling, bone bruising♦ Meniscal tear: signal change to free edge♦ Bone bruising:• Reticular—not continuous subarticular bone• Geographic—extends to subarticular bone♦ Posterolateral corner:• Oblique slices through fibular head• Consists of lateral collateral ligament, popliteus, popliteofibular ligament, and arcuate complex.Magnetic resonance imaging (MRI) has revolutionized the investigation and treatment of the painful knee. It is non-invasive and avoids patient exposure to ionizing radiation. MRI has the advantage of establishing diagnoses in a painful knee without the morbidity of surgical intervention. It is now widely available and has moved from a simple diagnostic adjunct into a key planning tool. It offers improved management of theatre resources and it allows for more accurate planning of postoperative rehabilitation.The role of MRI in management of the injured knee is determined by its cost-effectiveness and its ability to augment the diagnostic accuracy of clinical examination. Accuracy of clinical examination by specialist orthopaedic surgeons is comparable to MRI when interpreted by specialist radiologists (Table 8.3.1). Increasingly, MRI has been shown to be cost neutral. Whilst costs are high, diagnostic information reduces the need for unnecessary surgery.

Mri Findings

The knee is a very important joint and injuries affecting it may cause significant disability and discomfort to the patient. Despite a variety of methods available to assess injuries of the knee joint, Magnetic Resonance Imaging (MRI) continues to play a major role. This study evaluated the spectrum of MRI findings in a relatively low resource environment, with limited access to MRI modality. The outcome should justify further investment in MRI services in this locality. The study involves retrospective analysis of MRI reports of 198 clinically symptomatic patients referred for imaging in a Port-Harcourt. All examinations were performed using GE BRIVO MR 235 machine with 0.35 Tesla field strength in a well-coupled standard knee coil. All images were analyzed for normality or otherwise and radiological reports generated by competent radiologists. The most common findings are traumatic in origin, notably cruciate ligament tears (37.37%) and meniscal tears (33.3%) as well as quadriceps tendon tears (3.03%). The medial meniscus and anterior cruciate ligaments were more frequently involved. Furthermore, patients in the 3rd and 4th decade of life were more commonly involved, with a male preponderance. The less common findings of Synovial chondromatosis, cyst-like lesions, tumors and loose bodies, all buttress the importance of routine MRI in atraumatic cases. The spectrum of MRI findings in this study is a reflection of growing interest and confidence in MRI of the diseased knee joint in our environment. The outcome would be a justification for future investments in MRI. Keywords: Magnetic Resonance Imaging, knee injuries, tibial meniscal tears, incidental findings
