The Chinese versions of the Lysholm and Tegner scores are reliable and valid for assessing knee function in patients after total knee replacement.
Scores remained consistent when repeated 3–7 days later and aligned closely with the IKDC, supporting their use in clinical practice.
Key findings
01Test-retest reliability was high for both scales, with Intraclass Correlation Coefficients (ICC) of 0.99 for the Lysholm score and 0.97 for the Tegner scale.
02Both scales showed moderate correlations with the IKDC, a recognized gold standard for knee function, with coefficients ranging from 0.68 to 0.76.
03The Lysholm score demonstrated acceptable internal consistency with a Cronbach’s alpha of 0.71, and the smallest detectable change was 5.41 points.

What it does not show
The study used a cross-sectional design with different participants in each time-point group (pre-op, 3-month, 1-year) rather than following the same individuals longitudinally. The sample size was small (92 total participants). Some participants reported difficulty understanding ambiguous options in the scales due to cultural or language differences. The study did not include patients more than 1 year post-operation.

The easy way to misread this
Do not assume these scales are equally valid for non-Chinese populations or for patients with different knee pathologies (e.g., ACL injuries) without further validation, as the study specifically targeted Chinese TKA patients.
