“…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.…”

The relationship between the morphological characteristics of the infrapatellar fat pad (IFP) and joint deformity has yet to be fully elucidated. Therefore, the purpose of this study was to clarify the morphological characteristics of the IFP and to identify the relationships between morphological characteristics of the IFP and degenerative grade of the articular surface of the patella. This investigation examined 41 legs from 25 Japanese cadavers. The IFP length, width, and volume were measured. It was categorized into three types: Type I, IFP proximal located on medial and lateral sides of the patella; Type II, the IFP proximal only located medially; and Type III, absence of the IFP proximal. Articular surfaces were graded as macroscopically intact or mildly altered (Grade I), moderately (Grade II), or severely (Grade III). Grade III was significantly more frequent than Grades I or II in Type III. IFP volume was significantly larger in Type I than in Types II or III. A negative correlation was found between the degenerative grade of the articular surface of the patella and IFP volume. It was suggested that a relationship between the degenerative grade of the articular surface of the patella and the IFP volume.
