Les techniques macroscopiques et microscopiques incluantla microtomographie et le stéréomicroscope à zoom sont utilisées pour décrire la lésion.Extérieurement, l’ostéophyte a une texture douce et poreuse. La limite entre l’ostéophyteplus radiotransparent et l’os normal peut être identifiée sur les images de rayons X. NousWe present the palaeopathological study of a left patella (ATD6-56) belonging to theEarly Pleistocene species Homo antecessor (Atapuerca-Gran Dolina, Spain). The abnormalmorphology observed in the inferior margin of the patella is an osseous overgrowth (osteo-phyte). Macroscopic and microscopic techniques, including microtomography and zoomstereomicroscope, were used to describe the lesion. Externally, the osteophyte has a smoothand porous texture; the boundary between the more radiolucent osteophyte and the nor-mal bone can be identified in X-ray images. We suggest that the observed signs could besecondary to a local trauma. The lesion would have involved either the bone or related softtissues of the left limb, possibly affecting the stability of the joint. Consequently, the indi-vidual’s knee would have suffered an abnormal mechanical load that could have eventuallytriggered osteoarthritic changes. This is also supported by the lack of changes observed inthe associated right patella (ATD6-22).engjournal articlehttps://doi.org/10.1016/j.crpv.2016.04.014https://www.sciencedirect.com/science/article/pii/S1631068316300641?via%3Dihubopen access569.89599.892.3OsteophyteTraumaPaleopathologyPatellaHomo antecessorOstéophytePaléopathologieRotulePaleontología2416.05 Paleontología de Los Vertebrados
