“…Several studies carried out in different parts of the worlds also showed similar situation. In a study Yousif et al, (2014) reported that most of the patients (83.0%) were male and only 17.0% were female patients. Similarly, Sharma and Grewal (2020) highlighted in their study that 65.0% patients were male and 35.0% were female.…”

“…The most known clinical application is the ability to obtain a clear anatomical overview of the superficial structures around the bones. Soft tissue pathology of the knee represented one of the common uses since the nineties of the last century (Yousif et al, 2014). Ultrasound is a possible alternative to MRI and can be performed rapidly, is less costly, and can be used to evaluate muscles and tendons.…”

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.

“…15 MRI is the gold standard modality for diagnosing knee joint injuries. 17,18 Greyscale and Doppler ultrasound can also be used to detect knee joint injuries 19 but MRI is more sensitive in the case of knee fractures and meniscal injuries by producing high-quality tomographic images. 20 It is the sensitive, safe, and, non-invasive procedure for diagnosing ACL and PCL injuries accurately.…”

Introduction: The knee is a complex joint with numerous components and is susceptible to a wide range of injuries such as sprains, ligament rips, fractures, and dislocations. Objective: To characterize the knee joint injuries in traumatic patients using magnetic resonance imaging (MRI). Materials & Methods: A descriptive study based on retrospective data was conducted within the Radiology Department of Private Hospital Lahore, Pakistan, from September 01, 2021, to January 30, 2022, on 85 patients with knee joint injuries resulting from road traffic accidents and falls from heights. The data were analyzed for descriptive statistics using SPSS version 20. Results: The highest frequency of trauma was in male patients of age group 21 to 30 years. The common knee injuries were Joint Effusion 32(26.2%), Anterior Cruciate Ligament Tear 26(21.3%), and Posterior Horn of Medial & Lateral Meniscal Tear 16(13.1%). The most common cause for trauma was road traffic accidents. Conclusion: Magnetic Resonance Imaging was able to provide high quality images to diagnose knee joint status in patients suffering from traumatic injuries.
