简要总结
Knee osteoarthritis is a chronic disease common in middle-aged and older adults, characterized by functional impairment and reduced quality of life due to pain. While physical examination and radiographic Kellgren-Lawrence grading are frequently used in clinical evaluation, the severity of pain does not always correlate with the degree of structural degeneration. Ultrasonography is gaining prominence in osteoarthritis research due to its advantage of simultaneously evaluating both inflammatory and structural components, such as synovial hypertrophy, effusion, power Doppler signal, and osteophytes. The Outcome Measures in Rheumatology (OMERACT) working group has developed a standardized, multidimensional ultrasound scoring system for knee osteoarthritis, and this method is frequently used in the literature. This method consists of a diagnostic ultrasound examination lasting approximately 8-10 minutes. The examination evaluates the anatomical structures of the knee and also includes soft tissue examinations such as synovial hypertrophy. With this method, a diagnostic ultrasound examination lasting approximately 8-10 minutes is performed. The examination evaluates the anatomical structures of the knee and also includes soft tissue examinations such as synovial hypertrophy. Considering the differences between societies in cultural, genetic, biomechanical, body mass index distribution, and healthcare system practices, direct validity, clinical interpretability, and inter-study comparability are of significant importance. The validity, reliability, and applicability of the OMERACT osteoarthritis ultrasound scoring system have been reported in a study conducted on the Egyptian population. However, there is no data on the validity and reliability of OMERACT ultrasound scoring in the Turkish population. This study is the first prospective validation study aimed at establishing standardization for use in clinical practice in Turkey.

结局指标
主要结局
Western Ontario and McMaster Universities (WOMAC) score
时间窗: Day 1
The WOMAC Osteoarthritis Index questionnaire, consisting of 5 questions using a Likert scale, is provided in the attached case report form to assess pain, stiffness, and daily living functions. The WOMAC Osteoarthritis Index consists of 24 questions covering three subscales: pain (5 questions), stiffness (2 questions), and function (17 questions). The scoring system consists of the WOMAC pain score, WOMAC stiffness score, WOMAC function score, and WOMAC total score. A Turkish validity and reliability study has been conducted.
Outcome Measures in Rheumatology knee osteoarthritis scale
时间窗: Day 1
Participants' Outcome Measures in Rheumatology knee ultrasound parameters will be evaluated (The necessary permission to use the OMERACT ultrasound protocol in the study has been obtained from Dr. George Bruyn). Ultrasound evaluations will be performed on patients' bilateral knees by two blinded evaluators (the first investigator with 8 years of experience in musculoskeletal ultrasonography and the second investigator with 1 year of experience) using a Philips HD11XE device and a 4-8 MHz linear probe. Synovitis, synovial hypertrophy, effusion, power Doppler signal, cartilage damage, meniscal pathology, and osteophyte scores in the Outcome Measures in Rheumatology knee osteoarthritis scoring system will be evaluated according to Outcome Measures in Rheumatology definitions. A higher Outcome Measures in Rheumatology knee ultrasound score indicates a worse outcome.
