Patellofemoral Instability

by Sachin Ramchandra Tapasvi

This book on “Patellofemoral Instability” provides an overview of pathogenesis and treatment of patellofemoral instability. It details the elements that are necessary to appropriately understand, diagnose and treat patellofemoral instability ranging from dislocations in children to dislocations combined with total joint arthroplasty. The patellofemoral joint is composed of two osseous components, the patella and the femoral trochlear, which share an articulating surface. It is a sesamoid bone of a bi-articular muscle of the lower limb. Its function is intimately associated with the dynamic muscle activity of the lower extremity, including the global control of the limb underneath the torso as well as partnering with the tibiofemoral joint at the knee. Cartilage damage can result from patellofemoral dislocations, with potential consequences on future quality of life. More precise imaging, increased correlative injury anatomy, more focused physical exam features, and more anatomic surgical solutions, have led to enhanced clinician awareness and improved patient outcomes for patellofemoral dislocation injuries. This book will surely be a great help for all clinicians treating patellofemoral instability, and be used as a resource for years to come.
