This patient came to DALRI with knock knees (genu valgum) from surgery at another hospital. She received re-operation at DALRI twice and her legs have been perfectly corrected. She said "Dr. Lee and DALRI gave me a NEW LIFE and I am no longer afraid of walking or going out". We feel most rewarded at times like this:)
