“…The morphological characteristics of the IFP, in terms of exact size, shape and volume, appear highly variable. Previous anatomical studies have been performed on a small number of cadavers 1 , 3 , 5 , 11 , using magnetic resonance imaging 12 – 17 , ultrasonography 18 , and arthroscopy 19 . Focusing on gross anatomical research, Gallagher et al 5 reported that the IFP attaches to the infrapatellar pole, patellar tendon, meniscus, and anterior tibia.…”
