Rotational deformities of the lower extremity is a frequent reason to see the care of a pediatric orthopaedist. Though most children self-correct this finding by age 10, many do not and a subset of these patients develop knee pain or instability. We routinely measure rotational profiles in clinic, but if a patient is considering surgery we will obtain cross-sectional imaging to define their rotation. In the pediatric population this is frequently MRI and we have seen disparaging data clinically and radiographically. Our study has two arms: first we will retrospectively determine the inter-/intra-observer reliability of MRI to measure rotation of the femur and tibia.; second we will prospectively enroll patients presenting with rotational deformity warranting possible surgery to obtain MRI and compare to their clinical exam.
