Ultrasound findings in knee of patients of osteoarthritis and their correlation with pain
International Journal of Research in Orthopaedics, 2019
Background: Osteoarthritis (OA) is a common joint disorder, with the knee being one of the most frequently involved sites. Conventional radiography (CR), hitherto the primary imaging tool in OA, shows late and indirect findings. Ultrasound (US), on the other hand, offers the possibility to depict different structures within the knee. The main objectives of this study is to asses correlation of Ultrasonography (USG) findings of OA knees and pain assessed in each knee using a numerical rating scale (NRS) from 0 to 10.Methods: This study was a single center cross sectional observational study. Patients presenting to rheumatology clinic between February 2017 to March 2017 and satisfying ACR clinical criteria for osteoarthritis of knees were taken. Pain assessed in each knee using NRS. USG evaluation of painful knee was done using standard protocols.Results: In this study, 9 patients and 17 knees were examined. The mean age was 65.7 yrs with more females (66%) as compared to males (33.3%...

Osteoarthritis (OA) is a common degenerative musculoskeletal disease highly prevalent in aging societies worldwide. Traditionally, knee OA is diagnosed using conventional radiography. However, structural changes of articular cartilage or menisci cannot be directly evaluated using this method. On the other hand, ultrasound is a promising tool able to provide direct information on soft tissue degeneration. The aim of our study was to systematically determine the site-specific diagnostic performance of semi-quantitative ultrasound grading of knee femoral articular cartilage, osteophytes and meniscal extrusion, and of radiographic assessment of joint space narrowing and osteophytes, using MRI as a reference standard. Eighty asymptomatic and 79 symptomatic subjects with mean age of 57.7 years were included in the study. Ultrasound performed best in the assessment of femoral medial and lateral osteophytes, and medial meniscal extrusion. In comparison to radiography, ultrasound performed b...

Ultrasound is emerging as a viable imaging modality in the diagnosis and assessment of the musculoskeletal system. Advantages of ultrasound include its easy availability and multiplanar capability, as well as economic advantages. Unlike magnetic resonance imaging, ultrasound demonstrates the fibrillar microanatomy of tendons, ligaments and muscles, enhancing its diagnostic capability. The ability to compress, dynamically assess structures and compare easily with the contralateral side is advantageous. The patient's exact point of clinical tenderness can be correlated with underlying anatomical structures and associ-ated pathology. The main strength of knee ultrasound is the assessment of para-articular disease. The specific structures best suited for ultrasound assessment include tendons, muscles and ligaments, as well as periarticular soft tissue masses. Joint effusions, synovial thickening, bursal fluid collections, intra-articular loose bodies, ganglion cysts, ligament and tendons tears, tendonitis and occult fractures can be diagnosed. With experience, ultrasound is a time-efficient, economical imaging tool for assessment of the knee.
Dynamic Ultrasound in Morphological Assessment of Medial Compartment of Knee Joint Osteoarthritis
Zagazig University Medical Journal, 2019
Background: Osteoarthritis is a major joint disease between the elderly with the knee is the most common joint involved. Ultrasound is used for non-invasive assessment of knee joint status with evaluation of the meniscal position, joint space narrowing and presence of osteophytic lipping under load-bearing position for early detection of osteoarthritis. The aim of the study is to assess the role of high-resolution ultrasonography with dynamic assessment in evaluation of the medial compartment knee joint osteoarthritis.To investigate the correlation between the O.A grade determined by radiography and that by ultrasound evaluation and to investigate the diagnostic accuracy of O.A determined using US. Methods: This study was carried out at Radio diagnosis Department, Zagazig University Hospitals. The present study was carried on 35 patients of knee osteoarthritis. Diagnostic work up was done including plain radiography & MSUS. Results: Total of 38 of the 40 knees were correctly diagnosed by ultrasonography with sensitivity of 95 % and specificity of 80 %. The predictive value positive was 86.36 % and the predictive value negative was 92.3 % with 88.5% accuracy. Conclusions: Our results indicate that knee ultrasonography provides valuable information for the assessment of knee joint osteoarthritis. However, MSUS has an advantage of dynamic evaluation with qualitative and semi-quantitative assessment for early detection of knee O.A with good diagnostic accuracy.
An ultrasound score for knee osteoarthritis: a cross-sectional validation study
Osteoarthritis and cartilage / OARS, Osteoarthritis Research Society, 2014
To develop standardized musculoskeletal ultrasound (MUS) procedures and scoring for detecting knee osteoarthritis (OA) and test the MUS score's ability to discern various degrees of knee OA, in comparison with plain radiography and the 'Knee injury and Osteoarthritis Outcome Score' (KOOS) domains as comparators. A cross-sectional study of MUS examinations in 45 patients with knee OA. Validity, reliability, and reproducibility were evaluated. MUS examination for knee OA consists of five separate domains assessing (1) predominantly morphological changes in the medial compartment, (2) predominantly inflammation in the medial compartment, (3) predominantly morphological changes in the lateral compartment, (4) predominantly inflammation in the lateral compartment, and (5) effusion. MUS scores displayed substantial reliability and reproducibility, with interclass correlations coefficients ranging from 0.75 to 0.97 for the five domains. Construct validity was confirmed with sta...
Diagnostic accuracy of ultrasonography in the assessment of anterior knee pain
Insights into Imaging
Background Anterior knee pain (AKP) is a problematic complaint, considered to be the most frequent cause of orthopedic consultancy for knee problems. This study aimed to highlight diagnostic accuracy of ultrasonography as a fast imaging technique in assessment of patients with AKP. Methods and results A prospective study was conducted on 143 patients with clinically confirmed AKP. All patients underwent ultrasonography and MRI examinations of the knee. The diagnostic accuracy of ultrasonography compared to MRI for evaluating different findings of possible causes of AKP were analyzed using receiver operating characteristic (ROC) curve and judged by area under curve (AUC). A total of 155 knees were included in the study; 26 knees showed no abnormalities, 19 knees showed positive MRI only, and 110 knees showed positive ultrasonography and MRI. Ultrasonography and MRI reported 11 different findings of possible causes of AKP or related to it. Joint effusion was the most common finding (3...
Experience with Ultrasound of the Knee Joint at Mulago Hospital, Uganda
Background : The knee is prone to various pathology. Mulago Hospital records of 2001/2002 show that an average of 432 patients with knee joint disorders are seen in orthopaedic and rheumatology outpatient clinics out of a total of 5400 patients annually. For a long time the only mode of radiological investigation for these patients has been x-rays of the knee joints and this meant that limited information was got about the soft tissue component of the knee.Advances in technology with high frequency transducers, power Doppler ultrasound and extended field of view function have facilitated the progressive development of musculoskeletal sonography (MS). In developing countries like Uganda, where advanced imaging modalities like MRI are unaffordable and not readily available, ultrasound U/S serves as an efficient substitute in trained hands. This study was aimed at describing the sonographic pattern of knee joint pathology at Mulago Hospital in patients with knee joint symptoms. Methods...

To investigate the performance of ultrasonography (US) for the detection of knee osteoarthritis (OA) in patients suffering from knee pain, compared to conventional radiographs. Methods: Cross-sectional study performed at a university teaching hospital. Consecutive patients complaining of unilateral or bilateral mechanical knee pain who signed an informed consent were included. All patients underwent simultaneously an ultrasonographic and a radiographic evaluation of the knee. Exclusion criteria were age under 18 years, prior diagnosis of knee OA, diagnosis of inflammatory arthritis, history of knee surgery or trauma, severe knee deformities, and corticosteroid injection within the last 2 months. The diagnostic properties of US for the detection of knee OA were evaluated using radiological data as the reference method. Evaluated test properties were sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and the positive and negative likelihood ratio (LR+ and LR-). Results: Three-hundred twenty-two knees (281 patients) were included. Radiographic degenerative changes were present in 56.8% (183) of the evaluated knees. Regarding the diagnostic properties of the US, the presence of either osteophytes or the compromise of the femoral hyaline cartilage had the best sensitivity to detect OA (95%), with a NPV of 92% and a LR-of 0,07, while the combined identification of osteophytes and compromise of the femoral hyaline cartilage had the best specificity (94%), with 94% PPV and a LR+ of 13. Conclusion: US demonstrated an excellent sensitivity with an adequate specificity for the detection of radiographic knee OA.
The importance of using ultrasonography in knee osteoarthritis
The Egyptian Journal of Internal Medicine, 2012
Background Radiographic features of osteoarthritis (OA) do not correlate with its symptoms at the individual patient level; thus, conventional radiography has limitations. Ultrasonography plays an important role in the diagnosis of musculoskeletal disorders. It reveals soft-tissue abnormalities such as pes anserine bursitis, Baker’s cyst, effusion, synovial hypertrophy, meniscal tear, and collateral ligament injury. Aim of work The aim of this study was to detect changes in the knee that cannot be visualized using conventional radiography and to better understand and manage unexplained pain in OA. Results There was a discrepancy between the results obtained by clinical examination and those by ultrasonography. Knee effusion was found in 21 knees (70%); synovial hypertrophy was found in three knees (10%), of them two showed Baker’s cyst and marked effusion; Baker’s cyst was found in eight knees (27%); and pes anserine bursitis was found in one knee. Results that could not be found by...
