NCT05133934

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.

Outcome Measures

Primary Outcomes (4)

  • Patient-assessed Pain (rest pain) Visual Analog Scale (VAS) score

    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.

  • The Knee Injury and Osteoarthritis Outcome Score (KOOS)

    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

    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

    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)

Interventions

A cohort study will be used to collect patient data, analyze the clinical characteristics, TCM syndromes, and treatment of knee osteoarthritis in China

Eligibility Criteria

Age50 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

5000 patients who meet the diagnostic criteria for knee osteoarthritis from the 23 affiliated hospitals/centers across China will be recruited

You may qualify if:

  • The patient has repeated knee joint pain in the past month;
  • X-ray film (standing position or weight-bearing position) shows narrowing of the joint space, subchondral bone sclerosis and/or cystic degeneration, and osteophyte formation on the joint edges;
  • Age ≥50 years old;
  • Morning stiffness time ≤30min;
  • There is bone friction sound (sensation) during activity.
  • Patients who meet the diagnostic criteria 1 + (any 2 of 2, 3, 4, 5) can be diagnosed as KOA.

You may not qualify if:

  • Patients who do not meet the diagnostic criteria for knee osteoarthritis
