Titanium nitride (TiN) ceramic surface coatings have been developed to improve wear resistance and address concerns related to metal hypersensitivity; however, comprehensive wear data remain limited. This knee simulator study evaluated the performance of TiN\u2010coated titanium alloy (6 wt% aluminum, 4 wt% vanadium, balance titanium, Ti\u20106Al\u20104V) substrate femoral components compared with cobalt chromium (CoCr) femoral components. Mode I wear testing was conducted for 5.0 million cycles (mc) using highly crosslinked polyethylene tibial inserts, with wear rates and polyethylene debris morphology quantified. Mode III third\u2010body abrasive wear testing was performed on TiN\u2010coated femoral components using embedded 500\u2009\u00b5m TiN\u2010coated particles for 3.0 mc. Surface roughness was measured using White Light Interferometry (arithmetic mean height, Sa), and surface integrity was assessed using scanning electron microscopy. Following 5.0 mc of Mode I wear, volumetric wear rates were equivalent between TiN\u2010coated and CoCr femoral components (1.03 vs 1.04\u2009mm\n                    <jats:sup>3<\/jats:sup>\n                    \/million cycles;\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.001), with no notable differences in polyethylene particle size (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.114) or morphology. During third\u2010body testing, surface scratching of the TiN coating was observed without evidence of gross surface failure. As anticipated, the mean Sa of TiN\u2010coated femoral components increased through 3.0 mc of Mode III third\u2010body testing, while remaining lower than literature\u2010reported retrieved CoCr values (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.001). In conclusion, TiN\u2010coated femoral components demonstrated comparable in vitro adhesive wear performance to CoCr and provided improved resistance to abrasive conditions, where long\u2010term resistance to abrasion is expected to govern reduced wear.\n
