Historically, the patellofemoral articulation has been a topic of less interest among orthopaedists and has been subject to fewer studies when compared with other major joints in the body. Patellofemoral arthritis is a common and debilitating condition, and greater awareness of this has led to a new interest and recent increase in the number of clinical investigations pertaining to this condition. It is hoped that an overview of patellofemoral kinematics, forces, and contact patterns will help in understanding the progression of patellofemoral arthritis. Furthermore, this understanding will ultimately allow the surgeon to apply these basic principles to more effective nonsurgical and surgical treatment options. Treatment methods for patellofemoral arthritis include both conservative as well as surgical interventions. Specifically, these treatments range from stretching and water exercises to patellar realignment procedures and the recently developed procedure of custom patellofemoral arthroplasty. In addition, many new and innovative treatments are on the horizon. This renewed interest in the patellofemoral articulation bodes well for patients who suffer from this condition.
