English to Portuguese Medical Medical (general)

It is talking about radiographic views.
"If any clinical or radiographic concerns exist regaring varus or valgus alignment of the lower extremity, three-foot standing views are obtained to determine if a concurrent or staged tibial osteotomy may be required"

but I have no idea how I could translate this.
