Chinese translation and validation of the Oxford Knee Scale for patients with knee osteoarthritis.

PMID 30931046WHAT IT FOUND
The Chinese Oxford Knee Scale measured knee pain and function in 100 Hong Kong patients with osteoarthritis.
Answers were stable over 7 days and matched WOMAC pain and function. It may be used with Chinese-reading patients.
Key findings
01In 100 patients with knee osteoarthritis, Chinese Oxford Knee Scale scores correlated with WOMAC Osteoarthritis Index total scores (ρ = 0.832).
02In 30 patients, Chinese Oxford Knee Scale scores were stable over 7 days (intraclass correlation coefficient = 0.88).
03The Chinese Oxford Knee Scale correlated most with WOMAC pain (ρ = 0.846) and least with stiffness (ρ = 0.553).

What it does not show
The authors said 100 patients for 12 items may not be enough. Only 30 patients were tested for stability over 7 days. Patients had to be able to read and comprehend Chinese, so results do not cover illiterate patients. Only tibiofemoral knee osteoarthritis was included, and other osteoarthritis sites were excluded. The study was done in Hong Kong and not tested in total knee arthroplasty patients.
Declared interests
This study received no funding support.
The easy way to misread this
Do not read this as proof that the Chinese Oxford Knee Scale improves care or works for total knee arthroplasty patients. The study tested how the questionnaire performed in 100 Chinese-reading outpatients, and the authors said it needs testing in other cohorts.
