“…Those between the ages of 24 and 34 made up the largest demographic, while men made up 75% of the total. Moreover, Marwa et al (10) examined Thirty individuals who had been diagnosed with a possible knee ligament or meniscal tear. Those between the ages of 18 and 57 made up the bulk of the patients, with men being 70percent of the total and women making up 30%.…”

“…Furthermore, Cook et al (12) showed that US and MRI of meniscus pathology had similar levels of sensitivity (91.2 % vs. 91.7 %), specificity (84.2% vs. 66.7%), positive predictive value (PPV) (94.5% vs. 84.6%), negative predictive value (NPV) (76.2% vs. 80%), and overall accuracy (89.5% vs. 81.1%). Moreover, Marwa et al (10) found that 15 instances (50%) were identified with U/S as having a posterior horn of medial meniscus damage, whereas 18 cases (60%) were diagnosed with MRI. In spite of this, posterior horn of lateral meniscus damage was identified in both Ultrasound and MRI in 5 patients (16.7%).…”

Background: Among the most frequent causes of medical attention in the outpatient environment is knee pain or another knee condition. The capacity to guide percutaneous procedures and the fact that ultrasound may be performed anywhere, at any time, for a low price, and with excellent spatial resolution and image quality are all significant advantages of ultrasound. The patient may interact with the US machine in real time, allowing for quick clinical correlation and the opportunity and contrast the affected knee to the unaffected one. Structured assessment of the tendons, ligaments, joint space, osseous structures, peripheral nerves and vasculature, and the knee joint itself is possible by dividing the knee into anterior, medial, lateral, and posterior compartments. Aim of the Work: to assess US's capacity to characterise normal Knee anatomy, to explain US methodologies for thorough examination of the Knee, and to detect US manifestation of frequent pathologic diseases, as well as typical pitfalls/mimics of illness. Patients and Methods: Thirty people experiencing severe knee pain participated in this trial (less than three months duration). The orthopaedic outpatient clinic at Ain Shams University Hospitals and the ultrasonographic Imaging division of the Department of Radiology at Ain Shams University Hospitals collaborated on this work.Results: Regarding the demographic characteristics in the studied patients, it was found that Patients' ages varied widely, from eighteen to 70. with mean ±SD was 42.75± 13.1 years and median was 43.5 years. 18 (60%) patients were males and 12 (40%) of them were females with male to female ratio was 1.5:1. Regarding meniscal degeneration among the studied group, we found that the posterior horn is one of the most common areas for degenerative meniscus. Posterior horn medial meniscus degeneration was found in more than half (53.3%) cases while bone tenderness was found in 43 (95.6%) cases while the. Posterior horn lateral meniscus degeneration was found in eight (26.7%) cases. Conclusion:Ultrasound can help rule out potential causes of knee pain during the first stages of diagnosis. Joint effusion, tears to the posterior horn medial meniscus and the posterior horn lateral meniscus, bursitis of the anserinus, osteoarthritic alterations, cysts of the popliteal artery and duct, and tendinitis of the patellar tendon were the most common abnormalities detected by ultrasound. To verify our findings and assess US's diagnostic accuracy in knee pathology, more investigations are required with bigger sample sizes and longer followup.

Diagnostic accuracy of point-of-care knee ultrasound for evaluation of meniscus and collateral ligaments pathology in comparison with MRI

et al. 2021

Background Although magnetic resonance imaging (MRI) is often the “gold standard” for diagnosing knee problems, it has many limitations. Therefore, ultrasonography has been suggested as an effective rapid alternative in many knee abnormalities, especially after injuries of the meniscus and collateral ligaments. Purpose To determine the diagnostic accuracy of point-of-care ultrasound (POCUS) in detecting injuries of the meniscus and collateral ligament compared to MRI. Material and Methods An observational cross-sectional blinded study was conducted of 60 patients with clinically suspicious meniscus and collateral ligament injuries who were planned for an arthroscopy and or operative procedure. These patients underwent both blinded POCUS and MRI of the knees before the intervention procedure and results of both imaging modalities were compared according to the operative and arthroscopic findings. Results The preoperative reliability of POCUS compared to MRI for the assessment of meniscus injuries was sensitivity (92.9% vs. 90.5%), specificity (88.9% vs. 83.3%), positive predictive value (PPV; 95.1% vs. 92.7%), negative predictive value (NPV; 84.2% vs. 79%), and overall accuracy (91.7% vs. 88.3%). However, for diagnosing collateral ligament injures, POCUS versus MRI assessed sensitivity (92.3% vs. 88.5%), specificity (100% vs. 97.1%), PPV (100% vs. 95.8%), NPV (94.4% vs. 91.7%), and overall accuracy (96.7% vs. 93.3%). Conclusion Ultrasonography is a useful screening tool for the initial diagnosis of meniscal and collateral ligament pathology compared to or even with potential advantages over MRI, especially when MRI is unavailable or contraindicated. As newly advanced portable ultrasonography becomes available, it could be considered as a point-of-injury diagnostic modality.

Meniscal tears are mostly seen worldwide. Multiple imaging modalities are currently used to evaluate pathologic conditions of the knee. MRI can be referred as the non-invasive gold standard investigation to help establishing diagnosis of meniscal tears, but it economically unaffordable to most of patients and needs long examination times. Ultrasound is a possible alternative to MRI. It is simple, convenient and an inexpensive and non-invasive method. The use of ultrasound in identifying meniscal tears has been proposed, but its diagnostic accuracy remains controversial. The objective of the research is to define the diagnostic accurateness of ultrasound scan in detecting meniscal tears taking magnetic resonance imaging as gold standard. It was a diagnostic cross-sectional study in which 78 patients visiting Department of Diagnostic Radiology, Doctors Hospital, Lahore were included. Convenient sampling technique was used. Written informed consent was taken from all the patients. Patients were investigated with the help of ultrasound and results were noted on the designed proforma, subsequently the results were compared to the MRI scan of the knee joint. Data was entered and statistically analyzed using SPSS 21.0. Frequency tables were generated for all variables. For quantitative data like age mean and standard deviation were calculated and for qualitative data like sex and meniscal tears percentages were calculated. Sensitivity, Specificity, Positive Predictive Value, Negative Predictive Value was given. Bar and pie charts were used to present categorical data. Kappa analysis was utilized. The mean age of the patients was 38.18+12.818 years, 82.1% were males and 47.4% had sports trauma. Out of 48 medial meniscus tear on USG, 38(48.7%) were true positive and 10(12.8%) were false positive on MRI. Out of 10 lateral meniscus tear on USG, 9(11.5%) were true positive and 1(1.3%) was false positive on MRI. The sensitivity, specificity, PPV, NPV and diagnostic accuracy of ultrasound for medial meniscus tears were 95.00%, 73.68%, 79.16%, 93.33% and 84.61% while for lateral meniscus tears were 75.00%, 98.48%, 90.00%, 95.58% and 94.87%, respectively. Study concluded that ultrasound has good diagnostic accuracy when compared with magnetic resonance imaging in detecting meniscal tears.
