Patellofemoral arthroplasty has been utilized as a treatment for isolated patellofemoral arthritis for more than 30 years. However, the use of this procedure remains controversial, as many surgeons prefer to use total knee arthroplasty, even for isolated patellofemoral arthritis. While historically, the results with this procedure have been inconsistent, recent developments in prosthesis design and surgical indications have improved the outcomes of patellofemoral arthroplasty. Potential advantages of patellofemoral arthroplasty include a less invasive approach, less bone resection, less tissue destruction, shorter operative time, less blood loss, shorter rehabilitation, and more normal knee kinematics. However, proper indications and surgical technique are crucial in order to obtain optimal results. Some future modifications have the potential to further improve the outcomes of the procedure, although additional investigations are needed to further explore some of these aspects. This report will describe current knowledge regarding the indications and contraindications for patellofemoral arthroplasty, present the results and complications of this procedure, discuss alternative treatments for patellofemoral disease, and explore future directions for arthroplasty of the patellofemoral compartment.
