BACKGROUND Pain is the predominant symptom of knee osteoarthritis (OA) and the main reason of disability. Ultrasound is now one of the new imaging modality in Musculoskeletal medicine and its role in assessing the pain severity in the knee osteoarthritis is evaluated in this study. OBJECTIVES (1) To study the correlation between ultrasonographic (US) findings and pain score and (2) whether ul...

PURPOSE Osteoarthritic (OA) pain is largely considered to be inflammatory pain. However, during the last stage of knee OA, sensory nerve fibers in the knee are shown to be significantly damaged when the subchondral bone junction is destroyed, and this can induce neuropathic pain. Several authors have reported that tumor necrosis factor-α (TNFα) in a knee joint plays a crucial role in pain modul...

BACKGROUND Many people with radiographic knee osteoarthritis (RKOA) do not present with pain. It is suspected that such persons tend toward lower body mass index (BMI). The purpose of the study was to explore the relationship between BMI and knee pain among persons with RKOA. METHODS Subjects in the Clearwater Osteoarthritis Study with RKOA (N = 576) were classified as reporting knee pain (Pa...

UNLABELLED Discrepancies exist between radiographic osteoarthritis of the knee (OAK) and report of knee joint pain. Little is known about how these two definitions of osteoarthritis (OA) and their correlates differ between African American (AA) and Caucasian (CA) women. OBJECTIVE We compared the prevalence of radiographic OAK and knee joint pain in AA and CA women, and the congruency of these...

OBJECTIVES We explored a postulated association between daily driving time and knee pain. METHODS We used data from the Taxi Drivers' Health Study to estimate 1-year prevalence of knee pain as assessed by the Nordic musculoskeletal questionnaire. RESULTS Among 1242 drivers, the prevalence of knee pain, stratified by duration of daily driving (< or = 6, > 6 through 8, > 8 through 10, and > 1...

Knee pain is a common reason for a patient to seek medical evaluation. Of the many causes of knee pain, malignancy is one of the least common. When malignancy is the etiology of the pain, it is usually due to a primary tumor of the osseous structures or soft tissues of the knee joint. Metastatic disease involving the knee joint is uncommon, with few cases reported in the literature. Of these re...

STUDY DESIGN Cross-sectional study. OBJECTIVE To examine associations between frequent bilateral knee pain (BKP) and unilateral knee pain (UKP) and health-related quality of life (QoL). We hypothesized that frequent BKP would be associated with poorer health-related QoL than would frequent UKP and no knee pain. BACKGROUND Knee pain is one of the most frequently reported types of joint pain ...

 Abstract  Background: In the recent decade, many primary total knee arthroplasties have  been carried out in Iran and the number of revision cases is expected to rise with the  aging population. The aim of this study was to report the outcome of revision surgery  in the country and make a comparison between the outcome of revision and that of  the primary arthroplasty.  Methods: Retrospectivel...
