| Core Tip |
We investigated 845 lower limbs with primary knee osteoarthritis (OA) and detected an association between knee deformity and ankle joint alignment in the coronal plane. Varus knee alignment was the most commonly occurring and was strongly associated with varus ankle alignment, whereas valgus knees showed heterogeneous ankle adaptation. The hip to knee to ankle angle (HKAA) and the tibiotalar angle were moderately correlated, with knee alignment as the significant determinant of ankle alignment, independent of age and sex. OA severity (Kellgren-Lawrence grades) was associated with progressively greater varus alignment at the knee and ankle. The ankle joint will align beyond the accepted neutral range at specific HKAA thresholds of approximately 175.7° and 189.2° for varus and valgus knee deformity, respectively. These thresholds were consistent across sex and OA severity, underscoring the primacy of coronal knee alignment in driving ankle compensation. |
