[Tuberculosis of the patella. An unusual localization apropos of 2 cases].

Tuberculosis in an isolated localization in the patella is rarely reported. Five cases were found in the literature. Two new cases together with the radiographic work-up to be performed in case of a "painful" knee are presented. Histology of the curetage specimen is required to reach certain diagnosis and develop an adapted management strategy to protect the functional future of the knee.
