Clinical and ultrasonographic findings related to knee pain in osteoarthritis
Osteoarthritis and Cartilage, 2006
Objectives: To determine clinical and sonographic factors associated with painful episodes in patients with knee osteoarthritis (OA). Methods: In this cross-sectional controlled study, patients with primary knee OA (ACR criteria) were prospectively placed into two groups. Group A: 81 patients with knee pain during physical activity !30 mm in visual analogue scale (VAS) for pain for at least 48 h prior to inclusion; Group B: 20 patients without knee pain from at least 1 month prior to inclusion. Clinical parameters, knee radiographic and ultrasonographic findings were collected. The sonographic study assessed joint effusion in the suprapatellar pouch, infrapatellar superficial and deep bursitis, meniscal lesions, anserine tendinobursitis, and Baker's cyst. Results: Group A patients tended to be older and heavier women than group B (P < 0.05). The most frequent radiographic stage was III (57%) in group A, and I (35%) and II (35%) in group B, showing differences in the distribution of each radiographic stage (P < 0.005). The most frequent ultrasonographic finding in group A was suprapatellar effusion (79%), and in group B it was meniscal lesions (40%). Ultrasonographic findings showed in group A a significant increase of suprapatellar effusion (P < 0.001) and a tendency towards an increase of Baker's cyst (P ¼ 0.06). Suprapatellar effusion, Baker's cyst, and body mass index (BMI) were the factors associated with the appearance of pain after the logistic regression analysis. Conclusions: Suprapatellar effusion, Baker's cyst, and higher BMI are more frequent and seem to be risk factors of painful flare in OA of the knee.
Ultrasonographic features in symptomatic osteoarthritis of the knee and relation with pain
Rheumatology, 2014
Objective. Radiographic knee OA is moderately associated with pain. As OA is a disease of the entire joint, ultrasonography visualizing cartilage and soft tissue structures might provide more insight into the complex process of pain in knee OA. The objective of this study was to investigate the cross-sectional association between US findings and pain in knee OA.
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%...

Objective To examine the relation of radiographic features of osteoarthritis to knee pain in people with knees discordant for knee pain in two cohorts. Design Within person, knee matched, case-control study. Setting and participants Participants in the Multicenter Osteoarthritis (MOST) and Framingham Osteoarthritis studies who had knee radiographs and assessments of knee pain. Main outcome measures Association of each pain measure (frequency, consistency, and severity) with radiographic osteoarthritis, as assessed by Kellgren and Lawrence grade (0-4) and osteophyte and joint space narrowing grades (0-3) among matched sets of two knees within individual participants whose knees were discordant for pain status. Results 696 people from MOST and 336 people from Framingham were included. Kellgren and Lawrence grades were strongly associated with frequent knee pain-for example, for Kellgren and Lawrence grade 4 v grade 0 the odds ratio for pain was 151 (95% confidence interval 43 to 526) in MOST and 73 (16 to 331) in Framingham (both P<0.001 for trend). Similar results were also seen for the relation of Kellgren and Lawrence scores to consistency and severity of knee pain. Joint space narrowing was more strongly associated with each pain measure than were osteophytes. Conclusions Using a method that minimises between person confounding, this study found that radiographic osteoarthritis and individual radiographic features of osteoarthritis were strongly associated with knee pain.

Aims: The aim of the study was to evaluate the correlations between clinical symptoms (pain), physical examination, ultrasound (US), and radiological findings in patients with bilateral knee osteoarthritis (OA). Material and methods: Knee pain was appreciated during medial and lateral palpation of each knee joint and using visual analogue scale (VAS) and The Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC). US evaluation (osteophytes, meniscal protrusion, synovial fluid, femoral hyaline cartilage thickness) and radiological assessment (osteophytes, femoral-tibial space, Kellgren–Lawrence [K-L] score, enthesopathies) were performed by two examiners blinded to the clinical results and to each other. All these findings were scored with a five-point scale. Results: A total of 52 consecutive patients aged 63.44±9.49 were examined, 33 (80.5%) being females. In patients with bilateral knee OA the pain, evaluated by WOMAC score and VAS, was correlated with the presence ...
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...
Prevalence of Baker's cyst in patients with knee pain: An ultrasonographic study
2013
The objectives of this study are to investigate the prevalence of Baker's cyst (BC) in patients with knee pain, and to assess the correlation between BC and severity of osteophytes and joint effusion. A retrospective study was conducted on a group of patients with knee pain referred to our outpatient clinic for ultrasonography of the knee between January 2010 and February 2011. Patients underwent an ultrasonographic exam of the knees to assess the presence of marginal femorotibial osteophytosis, joint effusion and BC. A dichotomous score was assigned to each item (1 present, 0 absent) and severity of US signs of osteoarthritis and joint effusion were also graded semiquantitatively. Collected data were processed using logistic regression analysis to evaluate the correlation between degree of osteophytosis and joint effusion and BC. Patients affected by inflammatory joint conditions or with history of joint surgery or recent trauma were excluded. A total of 399 patients with knee pain were studied (299 women), in the age range 18-89 years (mean 56.2, SD 16.3 years). 293 patients (73.4%) showed sonographic features of osteoarthritis and 251 (62.9%) joint effusion. BC was found in 102 patients (25.8%) together with a positive association with sonographic features of osteoarthritis and joint effusion. Our data show a prevalence of BC of 25.8% in a population of patients with knee pain, and suggest that BC is positively related to osteoarthritis and joint effusion. Ultrasonographic examination of knee is worthwhile in patients with painful osteoarthritis or evidence of effusion.

Background: Knee osteoarthritis (KOA) is the most common cause of a painful joint, and it is associated with significant health economic consequences. About literature, KOA is usually diagnosed according to changes seen on conventional radiography, but the radiographic features of OA do not correlate with its symptoms. Nowadays, ultrasonography is becoming a non-invasive imaging tool for OA in the clinical setting. Thus, the purpose of this study was to evaluate the correlation between musculoskeletal ultrasound (MSK US) and the Western Ontario and McMaster University (WOMAC) osteoarthritis index findings in patients with primary knee osteoarthritis (KOA). Methods: Between August 2015 and October 2017, 50 patients with a mean age of 46.72 ± 9.12 years who fulfilled the American College of Rheumatology (ACR) criteria for KOA were included. All the patients underwent a clinical assessment with the calculation of the WOMAC index, and they underwent knee US examination and conventional radiography (CR). Spearman's rho was used to assess the association between MSK US findings and the WOMAC index. Results: The mean pain score was 10.08 ± 2.89, stiffness was 3.34 ± 1.72, physical function was 26.26 ± 9.6, and the total WOMAC score was 39.68 ± 12.83. Forty-seven knees showed radiographic femorotibial degenerative signs. The mean thicknesses of the ultrasound-measured articular cartilage of the medial condyle (MC), intercondylar notch area (IA), and lateral condyle (LC) were 0.23 ± 0.60 cm, 0.33 ± 0.69 cm, and 0.30 ± 0.81 cm, respectively. The US findings also included suprapatellar joint effusion (50%), medial meniscal extrusion (40%), and osteophytes (70%). A positive correlation was found between the mean articular cartilage thickness of the IA, mean pain score, and stiffness subclasses of the WOMAC score (r = 0.342, p = 0.015; r = 0.414, p = 0.003), respectively. Conclusions: The severity of KOA, based on articular cartilage thickness, showed good correlation with the pain and stiffness subclasses of the WOMAC score.
