Introduction: arthritis of the patellofemoral compartment is frequent in patients with gonarthrosis. Its signs and symptoms include pain and a feeling of instability. Objective: update and broaden knowledge on essential aspects such as epidemiology, predisposing factors, imaging, differential diagnosis and treatment of patients with patellofemoral osteoarthritis. Methods: a review was conducted of 200 papers published by Pubmed, Hinari and Medline using the information locator EndNote with the key term "patellofemoral osteoarthritis". Fifty-three citations were used, 46 of them from the last five years. Results: a discussion is provided of topics of great epidemiological interest, such as the frequency with which the patellofemoral compartment is involved, and the differences between patellar chondromalacia and patellofemoral osteoarthritis. A description is included of predisposing factors, among them patellofemoral dysplasia. Imaging studies, especially those based on axial patellar views, are described in detail. Reference is made to the importance of bone scintigraphy. A description is presented of the most common treatment modes and their main indications. Conclusions: the present review provides updated information about the treatment of patients with patellofemoral osteoarthritis, and sheds light on the differences between two conditions which are often confused in medical practice.

Palabras clave : patellofemoral osteoarthritis.
