Introduction:

Tumors around the knee are frequent, except for the patella, where its location is occasional. In this anatomical structure there are very specific clinical and epidemiological characteristics depending on the type of condition.

Objective:

To update and provide information on patella tumors.

Methods:

The search and analysis of the information was carried out in a period of 62 days (November 1st to December 31st, 2022) and the following words were used: patellar bone tumors, bone tumor AND patella, knee bone tumors. From the information obtained a bibliographic review was carried out, a total of 153 articles published in the PubMed, Hinari, SciELO and Medline databases through the EndNote search manager and reference manager were found, of which 30 selected citations were used to carry out the review, 28 of the last five years.

Results:

The incidence of the most frequent benign tumors that affect this anatomical structure, such as the Giant Cell Tumor, is mentioned. Reference is made to the most reported malignant bone tumors and their clinical and imaging behavior, especially Osteosarcoma. Metastases of the patella were addressed, particularly those of the lung.

Conclusions:

Bone tumors of the patella are infrequent lesions, when comparing their incidence with tumors from the rest of the knee joint. Presentation depends on the histological type and degree of bone involvement.
