Abstract: Clinical performance and microscopic analysis of a porous tantalum patella, retrieved from a 34-year-old male eight months after implantation is reported. The metallic tantalum represented 20 vol.% of the analysed patellar component. Tissue ingrowth was only in the large pores (up to 92%). Total tissue ingrowth was to the extent of 80%. The entire volume (including tantalum, small and large pores) had 64% tissue ingrowth. From the perspective of tissue ingrowth, the study supports the porous tantalum for clinical applications. This is the first report that evaluates the soft tissue ingrowth in a human retrieved trabecular metal patella.
