Overview
Brief Summary
A cohort study will be used to collect patient data, analyze the clinical characteristics, traditional Chinese medicine (TCM) syndromes, and treatment of knee osteoarthritis (KOA) in China to accumulate clinical data and clarify the status of KOA in the real world background. It will lay a clinical foundation for further study of KOA in the future, and bring certain clinical value for Chinese patients with KOA.
Detailed Description
This is a multicenter cohort study. It is planned to carry out multicenter investigation and research on the current situation of knee osteoarthritis in the real world, conduct large-scale investigation on the clinical population of patients with knee osteoarthritis, and establish a research, quality control, data management and statistical analysis platform for the clinical practical application of knee osteoarthritis and hospital registration. This study aims to discover the current clinical characteristics, TCM syndromes, and treatment status of patients with knee osteoarthritis in China, and provide reliable data support for the clinical treatment of KOA. It is estimated that 5000 patients from 23 centers across China will be recruited. Various demographic and disease-related information will be documented, including name, gender, age, job category, disease course, medical consultation experience, treatment satisfaction and so on. Patients will also complete a series of scales, containing Visual Analog Scale (VAS) Score, Knee Injury and Osteoarthritis Outcome Score (KOOS), Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index, 9-item patient health questionnaire (PHQ-9), SF-12 quality of life, TCM syndrome score sheet, etc. The primary outcome will be the pain (rest pain) VAS, KOOS, WOMAC knee osteoarthritis index score and TCM syndrome score. Secondary outcomes include patient's knee joint function examination, X-ray examination results, blood routine, biochemical indicators and pharmacoeconomic data.

Outcomes
Primary Outcomes
The Knee Injury and Osteoarthritis Outcome Score (KOOS)
Time Frame: 1 month
KOOS is a self-administered, knee-specific instrument to assess the patients' opinion about their knee and associated problems. The KOOS evaluates both short-term and long-term consequences of knee injury. It holds 42 items in 5 separately scored subscales: * Symptoms \& Stiffness (7 items) * Pain (9 items) * Function in daily living (ADL Function) (17 items) * Sport and Recreation Function (5 items) * Quality of Life (4 items) A Likert scale is used and all items have 5 possible answer options scored from 0 (No Problems) to 4 (Extreme Problems) and each of the 5 scores is calculated as the sum of the items included. Scores are transformed to a 0-100 scale, with zero representing extreme knee problems and 100 representing no knee problems as common in orthopedic assessment scales and generic measures. Scores between 0 and 100 represent the percentage of total possible score achieved.
WOMAC Knee Osteoarthritis Index Score
Time Frame: 1 month
WOMAC knee osteoarthritis index is a self-administered questionnaire consisting of 24 items divided into 3 subscales: * Pain (5 items): * Stiffness (2 items): * Physical Function (17 items) A Likert scale is used and all items have 5 possible answer options: none (0), mild (1), moderate (2), severe (3), and extreme (4). A total WOMAC score is created by summing the items for all three subscales (0-96), and higher scores indicate worse pain, stiffness, and functional limitations.
TCM Syndrome Differentiation and Symptom Score
Time Frame: 1 month
Patients' health as characterized by CM diagnostic pattern \& clinical characteristics is recorded using the standard of TCM syndrome differentiation that adopts the 2019 Chinese Society of Chinese Medicine Clinical Diagnosis and Treatment Guidelines for TCM Orthopedics and Traumatology - Knee Arthritis (Knee Osteoarthritis) Syndrome Differentiation Standard (cold-damp arthralgia syndrome, damp-heat arthralgia syndrome, stagnation of Qi and blood stasis syndrome, liver and kidney deficiency syndrome, and qi and blood weakness syndrome)
Patient-assessed Pain (rest pain) Visual Analog Scale (VAS) score
Time Frame: 1 month
The pain VAS is a continuous scale comprised of a horizontal (HVAS) or vertical (VVAS) line, 10 centimeters (100 mm) in length, each end of this scale is an extreme label of the symptom, "no pain" (corresponding to the scale of 0) and "pain too intense to be tolerated" (corresponding to the scale of 100). Respondents indicate their degree of acceptance to a statement by specifying a point on the continuous scale in between two endpoints. Using a ruler, the score is determined by measuring the distance (mm) on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity.
