Update on Patellofemoral Anatomy and Biomechanics
Operative Techniques in Sports Medicine
© 2019 Elsevier Inc. The anatomy of the patellofemoral (PF) joint is reflective of its primary function of knee extension and eccentric quadriceps contraction, as it operates as a functional unit to optimize weight-bearing during knee range of motion. Our understanding of PF anatomy continues to evolve with the use of new dissection methods, as well as improving imaging modalities. A proper understanding of PF anatomy allows us to describe the morphological abnormalities that may predispose to PF pain and instability, such as trochlear dysplasia, excessive lateral tilt, bony malalignment, and patella alta. With an understanding of PF biomechanics, clinicians can improve treatment of these disorders through targeted operative and nonoperative treatment options. The goal of this review is to provide a functional anatomical overview pertinent to the operative treatment of PF disorders.
