Both children with early and late type genu recurvatum show an improvement of minimum knee flexion after surgical correction of equinus.
In contrast to late type recurvatum, limbs with an early type showed a significant increased minimum knee flexion after equinus correction.
Equinus seems to be one of the most important underlying factors in early type recurvatum gait.
Further research should focus movement of the trunk, pevis and hip to identify further influencing factors contributing to genu recurvatum.
