Never encountered the problem of varus. Generally, there is no varus unless the lower tibiofibular ligament is broken.
The ligament of the medial and lateral ankle is harder than the bone, otherwise the ligament is broken, not broken.
The inferior tibiofibular ligament can only grow by itself, especially after surgery. The length of ligaments and bones is basically a matter of personal physique.
Mulberry can survive by cutting a branch into the ground, but cypress can't.
