Key Points

The study aims to determine the prevalence of varus thrust in adults with and without knee osteoarthritis, including variations across subgroups.
Systematic review conducted according to PRISMA guidelines
Search of five electronic databases and Google Scholar from inception to January 21, 2025
Inclusion of studies reporting varus thrust during gait assessed through clinical observation methods.
Varus thrust was found in 20.6% of knees and 26.9% of individuals with knee osteoarthritis (95% CI: 15.4%-27.0%, 21.6%-32.9%)
In individuals with varus alignment, prevalence reached 34.9% (95% CI: 27.6%-43.0%)
Prevalence increased to 54.3% in those with K/L grade 4 radiographic OA.
