Fig. 3From: Using short knee radiographs to predict the coronal alignment after TKA: Is it an accurate proxy for HKA on full-length images?Cases with a neutral FTA while a varus or valgus HKA. A and B The FTA is neutral (within 4°–9°) but the HKA is varus (more than 3°). C and D The FTA is neutral but the HKA is valgus (less than −3°). FTA, femorotibial angle; HKA, hip-knee-ankle angleBack to article page
